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! 🥰Translated from swedish

Love it!
This was probably the first product from Cosrx I tried, and I was completely converted😍 it actually gave visible improvement to my skin. Provides lots of moisture and glow, I think my skin quickly became more even and less textured. Super light and comfortable in consistency, absorbs quickly into the skin. I can't say enough positive things about this, because it is really actually fantastic good❤️ #lykoreviewTranslated from norwegian

Perfect for my sensitive skin
I recommend using it morning and night before the actual serum, and in the morning my skin feels wonderfully soft and balanced.191 viewsto leave a comment - 1 week
Niacinamide
How much niacinamide is in this?Translated from swedish
2020 views- Customer service at Lyko2 daysHi Monika 😊👋 I have been in contact with the brand, and they cannot disclose the exact content of niacinamide due to confidentiality reasons. All the best!

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 🧐Translated from swedish

I’ve written to the skin therapist Elvira and raised the question with her too 😊 Let’s see if I get any response. But great, then my skincare routine will be much easier if it works to combine. Thanks 🙏💕1 likes

Where in the routine?
Should this be used before or after retinol(evening)/c-vitamin(day)?☺️Translated from norwegian
2180 views- 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 😊)2 likes

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, MariaTranslated from swedish
1 likes1466 views- Employees at Lyko1 monthHey 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! ✨💙2 likes

Pregnancy and breastfeeding
I wonder if the product is safe to use during pregnancy/breastfeeding?Translated from norwegian
1581 views- Skin therapist at Lyko1 monthHeihei 👋 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 👋2 likes
