A New Total Favorite
My skin has been holding up pretty well without pimples lately, so much better than usual. And I’m pretty convinced that it’s since I started using this lovely product! I actually like everything I’ve tried from COSRX, but nothing has been as effective as this for me. I usually say that there are no miracle products, but this is actually almost one! 🙌 The product comes in a nice bottle with a pump. I usually take 4 pumps for my face. It’s thicker than water, but much lighter than gel. It sinks in very easily into the skin, but I often experience a little sting when I apply it, like niacinamide can do. A little with capital letters, because it’s really not a problem, but I’m also not particularly sensitive. It has a very interesting ingredient list! Hyaluronic acid, amino acids, and NAG are included, allantoin and niacinamide as well. And I can imagine that this product can suit many, with different types of needs for their skin. What I wish for, however, is regulation of oil production and a generally clearer and stronger skin. Take it with a grain of salt, but I feel that’s exactly what I’ve gotten! I’ve used it more intensively than I usually do with products, both morning and night. And I’ve had it as the first step after cleansing my face, because I imagine it’s most effective on completely clean and bare skin. Then I obviously have a whole bunch of products in my skincare routine, who knows if it’s the combination that works or a specific product... But it feels GOOD in any case, and I can absolutely recommend this! I will definitely buy it again when mine runs out, and that’s the best rating 💘 #lykoreview #COSRX #serum Adding this information that I learned the other day, because it doesn’t come up in the presentation of the product: peptides can become ineffective together with retinol, acids, and vitamin C. So use these in different routines OR let this sink in properly for a few minutes before you apply the rest of your routine, to get the most out of the content! 🥰18796 views - Most helpful negativeThe post was made 1 yearsRating: 1 out of 5verified customer
Not for sensitive skin

💧✨ A really nice booster for hydrated and smooth skin!
I have really fallen for COSRX The 6 Peptide Skin Booster Serum! This is one of those products that feels perfect when I want to give my skin extra moisture, radiance, and a smoother feel without applying a heavy serum. 🥹🤍 The first thing I like is the texture. It’s very light and thin, almost like an essence, and absorbs quickly. So I avoid that sticky feeling that some serums can leave behind. COSRX also describes it as a light serum that quickly penetrates the skin. What makes it extra interesting is the combination of six different peptides, niacinamide, hyaluronic acid, and allantoin. The idea is to help the skin feel firmer and smoother while moisturizing it and giving it a more even skin texture and tone. I especially think it works really well as a first serum step. After cleansing, I apply it directly to the skin and can then follow up with other serums or ampoules. COSRX actually recommends using it as the first serum step and that you can layer several thin layers if you want. 🤍 And 150 ml is hugely generous for a serum! 😂 That means I can use it quite liberally without feeling like the bottle will run out quickly. I also like that it seems pretty easy to combine with the rest of the skincare. It focuses more on moisture, skin texture, and general skin feel than on any super aggressive active ingredient, which makes it a flexible product to have in a routine. Lyko currently has a 4.6/5 rating based on 77 reviews, which is a really strong rating. The only small downside is that I wouldn’t expect any dramatic overnight change. This is more of a long-term booster that makes the skin softer, hydrated, and more comfortable. One Lyko review actually sums up the feeling quite well: the product is good, but not necessarily revolutionary. But as a light, moisturizing, and versatile first serum step, I think it’s really hard to complain about. 🥹✨ #lykocreator #lyko #beauty #beautytips #beautylover588 views - The post was made 2 weeks
Help with order
I was thinking of buying this and have the following other products – what order and what should I use morning/evening? 😊 - cleanser from La Roche Posay - glycolic acid - hydrating serum - vinoperfect brightening serum - retinol serum - vitamin c serum - peptide booster (this product) - 10% azelaic acid - dr althea 345 cream - eye cream with retinal - barrier serum - spf Please let me know if I should also spread some products out over the week ☺️💞510 views- The user's roll: Customer service at Lyko. The comment was made 2 weeksHi Hanna! Absolutely! 😊 You have many great products, but since you have glycolic acid + retinol + retinal in the eye cream, I would spread out the active products to reduce the risk of irritation. COSRX 6 Peptide Skin Booster can, however, be used daily and is applied directly after cleansing, before other serums. 🌞 Morning La Roche-Posay cleanser COSRX 6 Peptide Skin Booster Vitamin C serum Vinoperfect Brightening Serum Hydrating serum or barrier serum Dr. Althea 345 Cream SPF Retinol evening – 2-3 times/week Cleanser COSRX 6 Peptide Skin Booster Hydrating/barrier serum Retinol serum Dr. Althea 345 Cream Eye cream with retinal Azelaic acid evening – 2-3 times/week Cleanser COSRX 6 Peptide Skin Booster 10% azelaic acid Hydrating/barrier serum Dr. Althea 345 Cream Eye cream with retinal Glycolic acid – about once a week Cleanser Glycolic acid COSRX 6 Peptide Skin Booster Hydrating/barrier serum Dr. Althea 345 Cream All the best! ✨1 likes

Staple product
This is a must-have in the routine. Thin consistency, doesn't stick, but makes other products better.734 views - The post was made 3 weeksRating: 5 out of 5verified customer
Nice
I love how this serum feels on my skin. I’ve noticed that my skin is much calmer now. I use the serum once a day, every day.675 views - The post was made 1 month
Combine with other products
Hi, can this be combined with Excuviance Radiance serum? If so, how?959 views- The user's roll: Customer service at Lyko. The comment was made 1 monthHi Linn! 👋 What a great question! Yes, it is perfectly fine to combine COSRX The 6 Peptide Skin Booster Serum with Exuviance Radiance Serum. I recommend applying the COSRX serum first on cleansed skin, as it has a light texture and works as a moisturizing booster. Let it absorb for a little while, then apply the Exuviance Radiance Serum. Finish with a moisturizer, and always use sun protection during the day. If you have sensitive skin or are not used to active ingredients, it might be wise to start using the Exuviance serum a few nights a week and then gradually increase usage if your skin feels good. Hope this helps, have a great day 💖1 likes

Combine with antioxidants
Does this work together with Niche Beauty Lab Theramid Lino 8 Antioxidant treatment? I originally started using The Ordinary's Multi-Peptide + HA serum and their Multi-Antioxidant Radiance serum (was actually a bit put off by the comments on Lino 8 with my combination skin but still willing to try), but realized that the antioxidant serum doesn't work with some peptide serums, and I'm thinking that if I therefore replace the antioxidant serum and don't have vitamin C in my morning routine, I should just as well be able to include some copper peptides that this also contains? Also thinking that there is less risk of "pilling" with this?921 views- The user's roll: Customer service at Lyko. The comment was made 1 monthHello Anna! 👋 Thank you for your question! Yes, COSRX The 6 Peptide Skin Booster Serum and Theramid Lino-8 Antioxidant Treatment work well together and are a combination many appreciate. The COSRX serum has a light, essence-like texture with several peptides, including copper peptides, while Lino-8 contains a broad mix of antioxidants. Since Lino-8 does not rely on pure vitamin C (L-ascorbic acid), there is no known conflict between the products, so they can be used in the same routine. Compared to the combination from The Ordinary, this can also be a smoother alternative. The COSRX serum is very thin and absorbs quickly, which often reduces the risk of the products "pilling" when used together with Lino-8. If you have combination skin, it might be good to know that some find Lino-8 feels a bit richer in texture. However, that doesn’t necessarily mean it’s unsuitable; many with combination skin do well with it, especially if you adjust the amount or use a lighter moisturizer. I would recommend applying the products in the following order: COSRX The 6 Peptide Skin Booster Serum Theramid Lino-8 Antioxidant Treatment Moisturizer (if needed) SPF in the morning This creates a nice routine where you get both peptides and broad antioxidant protection at the same time. Hope this helps! Take care 💖2 likes

TIPS!
Love this 6-in-1 serum from COSRX! If you want an extra tip, I bought an empty mist bottle that I put the product in. Super nice to have as a spray instead of on the hands! 🌷🌷🌷 - The post was made 1 monthRating: 5 out of 5verified customer
Love love love (sensitive skin)
Love this. I like the watery texture that dries quickly before moisturizer. My sensitive skin loves this, and I feel it has calmed and evened out my natural red, irritated skin. Gives a beautiful glow. Nice under makeup. Would recommend.965 views - The user's roll: Lyko Creator. The post was made 2 monthsRating: 5 out of 5verified customer
A PRODUCT I ALWAYS WANT TO HAVE AT HOME
Bought after several recommendations from an influencer, and got hooked! Thin like water, which makes me use it more as an essence rather than a serum, but WOW how good my skin feels? Hard to really put into words what it does, but my skin feels well-cared for, clearer, and hydrated. Finished one bottle, planned to use up some other stuff at home before buying a new one – but missed it too much! So a new one is ordered and opened 🫶 An amazing product at a really good price! #kbeautysummer1995 views
