    The best serum I ever tried

    [This review was collected as part of a promotion.] I tried the L'Oréal Paris Age Defying Serum Le Duo for the first time, and I was impressed.

    The packaging is aesthetic with an easy-to-use pump.
    The serum has a gentle, amazing scent and comes in two different types of textures: a collagen peptide booster and vitamins B3 and C.

    After just one use, my skin felt calm without redness, was very soft, well-nourished, and radiant. I also noticed that my oily T-zone looked beautiful without any excess oiliness.

    After a week of use, my skin appeared younger and naturally glowed.

    This highly effective product reminds me the high-end skincare but comes at a low price.

    Recommending.

    Le-perfect-dont-walk-run-purchas❣️

    [This review was collected as part of a promotion.] Wow 👌 i absolutely LOVE this duo-serum, the packaging is great and most definitely eye catching 😀, the bottle is beautiful i just love how there separate untill you push down and both serum/cream come out together ❤️ when i say this leaves your face feeling so soft i mean it. I received this about 5days ago and use morning & night 🌙 this can be used under make-up aswell as does NOT leave any residue unlike some. Loreal le-due-serum really is a beautiful product and i honestly love it and would HIGHLY RECOMMEND to others. Although ive only used for around 5days i already see and feel the difference ( not massive yet) this is a 10/10 for me .

    My experience with L'oreal Paris Age Perfect serum

    [This review was collected as part of a promotion.] I've been using the L'Oreal Paris Age Perfect Defining L'Eau De Serum for two weeks, and it has made a significant difference in my skin. At 43, I noticed my skin starting to age, but this serum has been a game-changer.

    The lightweight, non-greasy formula absorbs quickly and leaves my skin feeling smooth and hydrated. Over the past two weeks, my skin feels firmer and has a noticeable glow, almost as if I’m 5 years younger. Fine lines and wrinkles appear diminished, and my overall complexion looks much healthier.

    The fragrance is pleasant, and the packaging is convenient. I highly recommend this serum to anyone looking to rejuvenate their skin.

    Nice texture and goes on easily.

    [This review was collected as part of a promotion.] From the outset, I thought that the packaging looked and felt top quality. I like the idea of having a dual serum, having used a similar more expensive previously, I guess this is L'Oreal's take on that serum. Nice texture and goes on easily. Doesn't leave a residue and has a light, pleasant fragrance. Worked well under my day cream. My skin felt soft and time will tell if my wrinkles reduce. The only negative for me, is that I'm not sure the dispenser is quite right at the moment. I did struggle to get equal amounts of each side and the dispenser for the darker side tended to clog up and had to be cleaned regularly. Overall, I like it!

    Amazing value for money with proven results

    [This review was collected as part of a promotion.] For start I love the design of this packaging it looks very premium and very classy. It is very practical having two serums in one and is amazing value for money. From using this product I have found that my skin is a lot more smoother and is radiating like it has never before with other serums. My skin overtime has become a lot more firmer and my skin tone is noticeably even now.

    I am so impressed with this product and have had so many compliments on the appearance of my skin, so much so that I have been wearing less makeup and feel so confident in my skin now. I have recommended this to my friends and family and will repurchase this product definitely

    Plastic container!

    [This review was collected as part of a promotion.] I got to try Le Duo Serum as part of L’Oreal’s tester panel. I found the serum easy to apply, quickly absorbing into my skin without it feeling sticky or greasy and leaving it feeling a bit smoother, more nourished. It does have quite a strong fragrance which I didn’t like but it does fade. It’s a bit too early to say if the serum will overall improve my skin but I’ll keep using it.
    The only thing I didn’t like is the container as it is all plastic (the Midnight serum is in a really nice glass bottle) and the inner tube containers aren’t clear or opaque so you won’t be able to see the amount of serum left, hence I gave 4*

    Leaves skin feeling lovely!

    [This review was collected as part of a promotion.] This serum is really brilliant. I didn't know what to expect from the duo. I put 1-2 pumps in the palm of my hands and rubbed my hands to mix serums together before applying all over my face and neck. I noticed immediately that the skin on my face looked softer and more hydrated. I was left with a pearlescent sheen on my face which is so beautiful. The scent is almost honey-like with a hint of amber. It is not overpowering, though. After a few days, I have noticed that my skin is looking smoother and feels really soft. Plus the modern yet chic bottle looks great on my dressing table. I will definitely continue to use this.

    Dream serum

    [This review was collected as part of a promotion.] The fragrance is so lovely such an addictive scent. The two serums mixed together are applied so effortlessly unbelievably light, saving time with the two in one and space on the shelf great idea. Not keen on the plastic style bottle looks great just feels cheap for L’Oreal I would have expected a little more class especially with the amazing product it was holding.
    The creams disappear quickly my face feels smooth not greasy nor clammy as I thought.
    I feel great so the lines near my eyes don’t seem as noticeable a little less deep, firmer skin and brighter something to smile about. Can’t wait to see what more will improve as the more days I use the more I notice.

    Scam of a product

    I purchased this product. The lid mechanism broke off and I couldn't put it back on. No dramas I thought then I looked and realised the total lack of product. The package is fancy but it is misleading. The product itself was blah.

    Excited to use the serum

    I used the serum on two mornings and everything was good.
    I didn’t use it today as I was going to get my face waxed.
    After some waxing on upper cheek area, the beautician asked if I’d been using anything different on my skin as I’d come out with a red shiny patch.
    I mentioned the serum.
    She wasn’t sure I should be using it after asking which vitamins it contained.
    Has this happened to anyone else? I have like a 2” strawberry mark on my face still.
    Hopefully it’ll go.
    Really wanted to use this product too after such good reviews.
    3 stars is due to being unsure if serum is responsible.

    Performs like a much pricier product

    [This review was collected as part of a promotion.] I'm enjoying using this serum, I have sensitive skin which can be reactive but I haven't had any issues with this. I find it moisturising but think drier skins might need a bit more. It's perfect for daytime use for me under a light moisturiser. I don't think I've been using it long enough to really notice any improvement however it feels a lot like a much more pricey serum I usually use so I'm confident it will perform similarly. My only issues are with the strong scent which although dries down quickly, seems unnecessary and the amount of plastic in the packaging, it seems excessive to me.

    Two in One Serum

    [This review was collected as part of a promotion.] I have enjoyed using this new and exciting product from L'Oreal for the last week. Le Duo Serum is very different from my usual serums, in the fact that the bottle contains two effective serums which pump out together and mix on the skin. One side contains a collagen Peptide booster which firms the skin and reduces the look of wrinkles, and the other has added Vitamins B3 & C which makes the skin more radiant. This has nourished and brightened my skin, and I love the immediate cooling and refreshing sensation when applied. A great addition to the Age Perfect Range.

    Le Duo Serum

    [This review was collected as part of a promotion.] I was really excited to try the Duo Serum.
    My skin has been a little dry recently do couldn’t wait.
    The fragrance was a pleasant albeit a little strong but as you only need a little, once on your skin, the smell dissipates.
    Straight away my skin looked brighter and the serum soaked into my skin really quickly. Can’r wait to keep using it.

    Sadly the pump on the bottle I got did not work so I had to decant it into another pump so that I could get the full benefits of the product, this is the only reason I have given it 4 stars but overall a brilliant product.

    Wow- it’s like the magic potion for my skin!

    [This review was collected as part of a promotion.] Wow! I didn’t know quite what to expect with this product but I love it!
    The packaging and presentation of the dual pump dispenser looks fab on my dressing table and makes it feel like a luxurious beauty experience when I use it. Love the combination of textures which somehow work perfectly together - it’s like magic!
    After literally two days use my skin is already instantly feeling soft, supple and more glowy on application & trust me it takes a lot for me to compliment my own skin!
    Love this and can’t wait to see the effects when I’ve used it for longer

    WOW!

    [This review was collected as part of a promotion.] Oh my goodness! This Age Perfect Duo Serum is incredible. The dispenser looks great and the difference in colours allows me to see both creams dispensed. The serums feels amazing on my skin and melts beautifully. This works on the first day of using and my skin felt hydrated instantly. The Collegan Peptide serum (white) and the Vitamins B3 & C (gold)combine when they are dispensed. I adore using this every morning. Due to the serums being good for the skin, it gives a perfect base to apply makeup! My skin looks amazing. I highly recommend this serum.

    Great results

    [This review was collected as part of a promotion.] I recently tested the Duo Serum, and it’s a standout product. The dual-chamber design delivers two serums that work together to address different skin concerns. It feels silky and absorbs quickly, leaving skin hydrated and smooth without any sticky residue. After a few uses, I noticed improved firmness and a more radiant complexion. It’s a great option for mature skin, combining effective ingredients that visibly enhance skin’s texture and glow. Overall, I love the two in one design and great results therefore I would recommend it to my friends.

    Baby soft skin

    [This review was collected as part of a promotion.] I love a 2-in-1 product that saves me time and has brilliant results! First of all the packaging is really pretty and the pump is easy to use, squirting both sides out at the same time. It smells divine, and is easy to rub in, absorbing quickly with no residue. I usually wait 5 minutes before applying moisturiser, and there has been no pilling of the product which is another bonus. I have only been using for 1 week so can’t comment on it reducing the appearance of fine lines, however it leaves my face baby soft and looking and feeling healthy.

    L’Oreal Duo Serum.

    [This review was collected as part of a promotion.] The first thing that I noticed about the L’Oreal Age Perfect Le Duo Serum was the tactile nature of the packaging. I love the idea of combining two beneficial treatments in one dispenser. When I combined the serum I saw that it became a gold colour, which gave a golden hue to my skin when applied to my face. I have only been using the Serum for a short period of time and I’m fortunate not to have many wrinkles, so I cannot comment on the aspect that the serum reduces wrinkles. My skin felt moisturised and brightened after applying the serum.

    Impressed With This Product

    [This review was collected as part of a promotion.] I love the packaging on this bottle of "Age Perfect Le Duo", it's very classy and catches the eye immediately. I actually like the fact that it is basically two products in one bottle. Collagen Peptide Booster Vitamins B3 on one side and Vitamin C on the other.
    The is a very slight scent which seems to dissipate when the combination cream is applied to the skin. It's a lovely soft scent.
    I honestly believe I could tell the difference after using this, within 24 hours. I know for sure that my skin felt so soft and smooth, it was amazing. My facial skin stays soft all day, and looks refreshed, IMHO. I also apply it to the neck area.
    Try it, what have you got to lose besides tired looking skin ! I love it personally, and would recommend it highly.

    Highly recommended

    [This review was collected as part of a promotion.] After I tried the L'Oréal Paris Age Perfect Le Duo Serum I fell in love with the product and the results. This serum has become an essential part of my daily skincare routine. The dual design is not only looks beautiful , but allowing the ingredients to remain separate until application ensuring freshness and effectiveness. I noticed an immediate improvement in the texture and hydration of my skin. The serum feels lightweight and absorbs quickly without leaving any greasy or sticky residue. It feels so smooth and velvety on the skin. Overall, the L'Oréal Paris Age Perfect Le Duo Serum has exceeded my expectations. It's an excellent product for anyone looking to enhance their skincare routine with a high-quality, effective serum. Highly recommended!

    Potential to be a fantastic serum

    [This review was collected as part of a promotion.] I was sent a sample of this for review. Unfortunately the pump section was broken during shipment so I haven't been able to fully test the duo aspect of this serum. But I have been very impressed by the brown coloured section of the serum (thankfully it hadn't all leaked unlike the white section had). My pores look blurred and my complexion is evened out. I will definitely be buying this to try out the full duo effect as the solo one has impressed me significantly. It's not cheapest serum on the market, but worth a try when on offer.

    Interesting delivery system

    [This review was collected as part of a promotion.] First of all, I do like the dual delivery system of this but not sure if it's necessary to separate the two serums within or if it's a stylistic/design thing. You do have to press the top fairly evenly in the centre to ensure you dispense equal amount of product from both sides which may be an issue for some with disabilities, etc. The serum itself was a nice texture that settled in to the skin well, highly fragranced though which may not suit all. Too soon to say its had an effect on wrinkles and firmness but looks promising so far

    Decent but not amazing

    [This review was collected as part of a promotion.] I’ve been using this serum for a little while now, but not long enough to see the effects promised after 4 weeks - but honestly I’m not noticing any potential difference in fine lines etc, and I would have expected some progress by now! However, it’s still a nice enough serum. It was a little difficult to get the hang of dispensing both liquids equally and it’s much more perfumed than I usually like in a facial product. It’s not bad though & I’ll keep using it for now see if it can produce the promised results on my fine lines!

    The Best Serum I've tried!

    [This review was collected as part of a promotion.] This really is the best serum I've ever tried and I've tried a lot! It is so luxurious I just feel that it's working magic! Two serums contained in a unique dispenser it looks high end! And I can vouch it feels it too, but this is one serum I intend to continue using, it is so lovely. Containing an oil and cream that, after priming the pump, mix alongside each other to blend onto face. I started with 2 pumps that covered my face and neck but even after a couple weeks I'm just using 1 pump and following with my usual Age Perfect day cream. My skin has never felt so soft and nourished and I am delighted with the results so far. There isn't a discernible fragrance that I have noticed. Absolutely recommend this gorgeous product and hope it never gets discontinued!!

    A powerful serum to give a boost

    [This review was collected as part of a promotion.] I'm at that age where the fine lines and wrinkles are starting to kick in so it was really good to be able to see what this new product could do.
    I've tried quite a few serums in the past but this has two, that once you’ve pressed for a pump comes out together. Once I'd cleansed my skin I applied this to my face and I didnt need much at all to cover it. It has a nice texture to it and didnt leave my skin feeling tacky. It did look a lot brighter though and I'm keen to see how it fares over time at improving my fine lines.

    Good hydrating serum

    [This review was collected as part of a promotion.] This serum looks extremely high quality with luxury packaging and different looking bottle. The serum comes out separately when you press the pump, and then merges together as you apply it to your skin. It is very easy to apply and absorbs quickly and easily into your skin. It left my skin looking more radiant and with a better texture, and also my skin felt soft and supple to the touch. I have used the serum now for 2-3 weeks and can definitely see an improvement in my skin. I would recommend this product completely.

    Wow!

    [This review was collected as part of a promotion.] This serum is amazing! I read that you should see some visibly signs I think within a week and I'm not joking when I say I can see a change in my skin! My fine lines around my eyes are barely visible now (I'm 48 and have fine lines, texture and dry skin)! My smile lines have also lessened too. I love the silky feel it gives to my skin without feeling greasy. I want to say my skin almost feels like I've putt powder or talc on it. It's so smooth. I like the fragrance which is light and how it wears under my makeup (I only use this in the day time and a different serum at night). Over all, I really love this Duo serum and would definitely repurchase. I'm hoping they bring out an eye serum similar or even in same range (I have been applying this all over my face though).

    Unususual and rather lovely Serum.

    [This review was collected as part of a promotion.] This is a lovely serum the fragrance is lovely and it goes smoothly and easily onto my skin. I thought it might be a bind to get it out of the bottles and mixed but it is easier than most serums that I have used as the pump action delivers exactly the right amount. A lot of serums leave my face slightly dry but this this one does not, and it is not cloying or greasy either. I haven't yet seen any tangible benefits but my skin feels better after using this once a day for 5 days, it feels less tight and much smoother.

    Fabulous skin

    [This review was collected as part of a promotion.] I really love this product it’s so good for my skin I can’t really use anything too harsh on my skin at the moment so this is perfect it gives you that double hit of moisture half is cream & the other half is a serum so it’s time saving too as you get them both in one pump of the applicator & it really soaks in so your skin is hydrated but not left feeling greasy at all it just gives you a Heathy looking glow I will definitely continue to use this daily & look forward to the continued improvement of my skin.

    Highly recommend

    [This review was collected as part of a promotion.] I absolutely love this new Duo serum. It’s definitely the best I have tried for a long time.
    From the first use it immediately made my skin smoother and lovely and soft
    I’ve only been using for about 10 days now but my ageing skin looks better than it has done for ages and has definitely started to reduce the lines around my eyes.
    The duo bottle is great and disperses even amounts of both cream and oil.
    An added bonus for me is that I don’t get spots like I do with a lot of oil serums.
    Highly recommend.

    Great results

    [This review was collected as part of a promotion.] I have been using this serum twice a day for two weeks and found my skin looked smoother, firmer and lines less noticable, already. The formula is super light and absorbed quickly leaving no sticky residue. The only criticism I would have is that the fragrance did have quite a scent of alcohol on it which I found a little off putting and if applied to skin that was not quite dry enough (after cleansing) I experienced seperation and balling of the serum..but otherwise I was impressed with the results!

    Match made in heaven

    [This review was collected as part of a promotion.] A match made in heaven - I love love this serum. Such a clever bottle – the outer casing is transparent so you can see the contents of each of the two chambers of goodness.
    When you depress the top this “cleverness” dispenses the same amount from each chamber into the palm of my hand and it’s ready to apply.
    It’s a dream to apply and it goes on like silk with no stickiness whatsoever and is instantly absorbed. So impressed as the effect is immediate radiance – this is the best serum I have ever used

    Super smooth skin

    [This review was collected as part of a promotion.] This is a lovely feeling product, and the mixture of the two things really does seem to improve the texture, appearance and smoothness of my skin. It looks expensive, and even smells pleasant, so I’m enjoying using it morning and night after cleansing. Only downside was that the brown part of this duo gave up working for a couple of days and being a sealed unit, I couldn’t see how to rectify this fault. I used a tiny pin in the end, and it’s now working again. Otherwise, a lovely skin booster.

    Love this!

    [This review was collected as part of a promotion.] I’ve been meaning to try this for a while and finally got round to it. Nice packaging and good dispenser. Just the right amount is dispensed with one pump. Nice light scent, not overpowering. Feels lovely on my skin. I like to leave it to sink in for a few minutes before applying my daily moisturiser and find that I need a lot less moisturiser. Not been using it long enough to notice any visible difference to my skin but will keep using. Lovely product and feels like a treat for your skin.

    [This review was collected as part of a promotion.] What a lovely product. When you first use it you instantly notice that it has a gorgeous fragrance and a good texture. It's amazing how the dispensing bottle works to get just the right amount of each serum so that there is enough to mix together and spread evenly. It's quickly absorbed too. Within hours of using it you can feel how soft your skin is. I've used it for a few weeks now and I have started to notice that my wrinkles are not as obvious which boosts my confidence greatly.

    Nice product, horrid packaging

    [This review was collected as part of a promotion.] The texture of the serum is lovely, absorbs really nicely onto my skin. Didn't make it greasy or oily.
    My issue is with the packaging. First for 30mls it's a massive "bottle" - it seems a lot of style over substance - I realise it's trying to show the two formulas but I'd rather have something a bit smaller. Pumping out the serum it doesn't come out that nicely, it leave residue on the nozzle which then smears all over the lid. Honestly there should be a better way of dispensing this

    This has made a noticeable difference to my skin

    [This review was collected as part of a promotion.] Very impressed by this. I have used a few duo serums in the past and this one is definitely as good as those. It feels lovely on your skin and I actually noticed very quickly that my skin is firmer along my jawline and the fine lines by my eyes are less noticeable. My skin also feels very nourished and soft and it looks more radiant.
    The pump container is easy to use with no mess and the two serums come out evenly each time. You only need to use a couple of pumps for every application of the serum as it spreads very evenly and easily on your skin. It is not oily or sticky and just feels comforting and caring and I like the light fragrance and silky texture of Le Duo. I have been using this every night and I promise you I have noticed a difference and quickly too, I am very pleased with this fab serum.

    Unfortunately caused irritation

    [This review was collected as part of a promotion.] ### Product Review: L’Oréal Duo Serum

    The L’Oréal Duo Serum boasts an impressive blend of ingredients, making it a standout product.

    However, despite its promising formulation, the inclusion of fragrance is a significant downside. Fragrance can be a common irritant, especially for those with sensitive skin. Unfortunately, I found that this serum did cause some irritation upon application, which I suspect is due to the added fragrance. While the product performs well in terms of texture and absorption, the irritation was a dealbreaker for me.

    For those who are not sensitive to fragrance, the L’Oréal Duo Serum might be a great addition to their skincare routine. However, for individuals with sensitive skin or those who prefer fragrance-free products, it may be wise to approach this serum with caution.
