    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! 🥰

      Thank you best you! ❤️❤️ For a relatively new beginner on this with different products and their contents 🙈 Are there peptides in the serum from Cosrx?

  • Contraindication

    I recently learned from the skin therapist Elvira on Youtube about peptides, among other things, that they can become ineffective when combined with retinol, acids, and vitamin C. So I almost think you should add to the description of this product that one should use peptides in a routine separate from these mentioned, alternatively one needs to let this serum sink in thoroughly into the skin before applying the rest. To get the most out of this product, I think it's a good thing to tell people? Or what do you think? Best regards, Johanna 🧐

    Where in the routine?

    Should this be used before or after retinol(evening)/c-vitamin(day)?☺️

    • Hey! I saw your question and I think Lyko might be misinformed, because the thing is that the peptides this contains can become ineffective together with both retinol and vitamin C. Source: skin therapist Elvira (on Youtube, she has an episode specifically about peptides) So what I would recommend you do is either use these in different routines or remember to let this serum sink in properly into the skin before applying the rest. So for a few minutes. Just wanted to give you this tip so you get the most out of your product. Writing to Lyko as well. Best, Johanna (not a skin therapist, but a skincare enthusiast 😊)

    Can't really see a difference

    I have been using this for months now. I honestly can't really tell a difference in my skin, so l don't know how to rate this. I'm sure it's a quality product, but also if someone sold me this same bottle full of tap water l'd never know. #lykoreview

  • Peptides in my routine

    Hi! I'm eager to try a peptide serum and have some questions about how it fits into my routine. My morning routine: Toner with HA, vitamin C serum, Kiehl's ultraface cream, SPF Evening routine: Cleansing with balm, toner with HA, Jorgobé niacinamide serum, retinol or AHA mask, cicaplast My skin is dry, but handles active products well. I hope you can help find the right place for this product, as I'm so eager to try it :) Best, Maria

      Hey Maria! 👋🏻☺️ How fun that you want to try a peptide serum! You can easily incorporate the COSRX Peptide Serum into your routine: 🌞 Morning: After your toner with HA, before vitamin C. 🌙 Evening: On non-retinol/AHA evenings – after toner, before niacinamide. On retinol/AHA evenings – after the active steps, before Cicaplast. It fits well with your products, but if you notice irritation, you can use peptides on the evenings you skip active ingredients. Hope that helps and good luck! ✨💙

    Pregnancy and breastfeeding

    I wonder if the product is safe to use during pregnancy/breastfeeding?

      Heihei 👋 The product can definitely be used during pregnancy and breastfeeding 🤰 During pregnancy, the general advice is to avoid products that contain retinol (Vitamin A). You should also avoid active ingredients like acids. Since the skin is extra sensitive during pregnancy and breastfeeding, you should make sure to use UV protection every day, as pigmentation can more easily occur during this period. Wishing you a nice day ahead 🥰 Wishing you a nice day ahead 👋

    Niacinamide

    How many percent of niacinamide does this contain? Can it be combined with vitamin C or azelaic acid?

      Hey Monika✨ When I look, it seems this contains 2% Niacinamide. Regarding the combination of products, I would always say it's best to test on a small area first to see how the individual skin reacts. Otherwise, I recommend using these products in different routines and on different days of the week instead to be on the safe side🤲🏼 Wishing you a super nice day😊
