    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! 🥰

    Not for sensitive skin

    Sadly this product lets me break out.

    So satisfied!

    I love the COSRX 6 Peptide Serum. Noticeable difference in skin firmness. Plus, it’s often on sale, which makes it a budget steal for what it does! So I buy it over and over again ❤️ As someone with dry skin, it doesn’t quite meet my moisture needs, but I mostly use it for extra firmness in my skin 😊 I’m 31 years old, by the way.

    A little question

    Can this be used together with Medicube? 😃

      Hey Cim!😊 Yes, you can most likely use this together with products from Medicube without major issues. Peptides often work well in combination with other skincare ingredients and do not negatively affect each other's effectiveness in most cases. Take care!🤎

    Good serum

    - Light consistency, absorbs easily into the skin. - Smells mild. - I feel like my skin has gotten a bit more glow after 2 weeks of use. - I usually get breakouts from products after 3-4 days, but no breakouts so far.

    Before or after toner and essence?

    Hi, I’m wondering if this should be used before or after toner and essence? I have just switched my essence to this and am using it after toner and before serum, but I just read that it should be the first step. It feels strange to put something on before the toner, but is that the idea behind this since it’s a booster?

      Hey Sara! I understand that it can get confusing sometimes with all the steps in a skincare routine ❤ The idea is that you should be able to use it after your cleansing as the first step in your skincare routine before moving on to the next product! 😍👍

    Awesome!

    Awesome serum! I bought this serum a while ago and then it sat in the bathroom cabinet, but I have now tested it for the last 4 weeks along with the eye mask with Collagen from the same brand. I find that it is a very moisturizing serum and my skin looks/feels both smoother and firmer. I love the pump packaging. If I had to mention something negative, the product feels a bit watery. I also find it to be fragrance-free, which is a big plus! In short! A really good Skinbooster that gives a nice glow! My skin loves it! #tävling

    Toner with many functions

    I have previously used different serums for moisture/tightness/acid. I find that this contributes to all 3. It is also beautiful and easy to apply with a few pumps directly into the hand (skip the cotton for the environment <3), also light in consistency so that one bottle lasts a long time.

    Serum

    I had high expectations for this serum since I love this brand. Unfortunately, I felt that this serum didn't do anything special for my skin. I've used up the bottle and actually see no results at all.

    During pregnancy

    Can the product be used by pregnant women? If not, what do you recommend instead?

      Hi Louise Mikaela! There’s a bit of repetition in this answer. Based on the ingredients/INCI, it looks okay, i.e., no retinoids, salicylic acid, or other strong acids. Also, no perfume that could cause irritation since the skin can become more sensitive during pregnancy and breastfeeding. But it’s also important what suits your skin right now? 🙏 If you have more questions, you can email 💌 hudterapeuten@lyko.com Take care and good luck 🌸

    Plumping

    Gives an instantly plumped and hydrated look, absorbs nicely into the skin and provides a lovely glow. Reduces fine lines and pore size, on my 3rd one now, will buy again :)
