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

Good under night oil
I use this every night under a facial oil (jojoba). I really like it, but I can't see any big difference. I generally have combination skin, but I think it does the job since I haven't gotten any "worse" skin. Good price for the amount of ml.Translated from norwegian

Use
How many times a week can I use this, and how do I use it in relation to the BHA acid from cosrx?Translated from norwegian
416 views- Customer service at Lyko1 weekHi Vilde 💛 Thank you for your question! COSRX The 6 Peptide Skin Booster Serum is a lightweight and hydrating serum that strengthens the skin barrier and gives glow, and it can be used nicely in the morning and/or evening – every day. It does not contain acids, so it is also suitable for sensitive skin. When it comes to using it together with COSRX BHA (salicylic acid), you can follow this order in your skincare: Cleanse COSRX BHA – feel free to wait 10–20 minutes to let it work 6 Peptide Serum Moisturizer and/or sunscreen (during the day) BHA penetrates the pores and works with sebum and impurities, while the peptide serum provides moisture and supports skin repair – they complement each other very well! 🌿

Combine this with Purito's serum?
Can you combine this with the PURITO Wonder Releaf Centella Serum? It contains some type of peptide as I understand it. Is it too much to combine? :)Translated from swedish
388 views- Customer service at Lyko1 weekHey!🤍 Yes, you can absolutely combine the COSRX The 6 Peptide Skin Booster Serum with the PURITO Wonder Releaf Centella Serum. They complement each other nicely; COSRX hydrates and prepares the skin with peptides, while PURITO soothes and strengthens with centella and a milder peptide complex. Use COSRX first, then PURITO. It won't be too much, on the contrary, a nice duo for both strength and calm in the skin! 💧🌿 Take care!🌞1 likes

When?
Should this be used before or after beplain chamomile ph-balanced toner?Translated from norwegian
402 views- Customer service at Lyko2 weeksHey Anette 💌 Cosrx The 6 Peptide Skin Booster Serum works as a booster step and is made to be used before other products – including toner – to prep the skin and improve absorption. 👉 Order: -Cleanser -Cosrx Peptide Booster -Beplain Chamomile Toner -Serum(s) -Moisturizer But: If you feel that the toner calms the skin best first, you can definitely switch the order – skincare is also about what your skin likes💛 Wishing you a nice day ahead!2 likes

I have never been good at using anything other than a moisturizer morning and night in my skincare routine, but this has become a new staple both morning and night! It has helped my dehydrated skin and given me a more even skin tone ✨ The pump bottle is also very convenient!Translated from norwegian

Illegal Marketing
You have raised the price from 172 to 238 this week, which corresponds to more than a 30% price increase, and you have run a campaign that there is a 30% discount if you buy 2 products. I actually don't think that's legal according to the marketing law.Translated from norwegian
2 likes390 views- 2 weeksThanks for the reply! It is still misleading even though you have found a loophole in the law. Luring with discounts if you buy 2 products is something many fall for, precisely because they think they are saving money. In this case, Lyko has raised the price by more than 30%, just to make the consumer believe they are saving 30% by buying 2 products, which they absolutely are not. I see that you have started running such campaigns on several products and do exactly the same, raising the price before the campaign starts.2 likes

I googled this product and researched a lot about which products can be combined and which cannot. A skincare specialist said that peptides can be combined with both vitamin C and retinol, and that peptides helped and enhanced the vitamin C and retinol. She recommended using the same routine. Of course, I don't remember her name.. What does the community say/think? 😁Translated from norwegian

Question about composition
Hi. I use Elixir Niactil 4% serum as a day cream and then sunscreen. Can this be combined with it? And possibly serum vitamin C 23?Translated from norwegian
1662 views- Customer service at Lyko2 monthsHi! 😊 Cosrx The 6 Peptide Skin Booster Serum is a serum with multiple peptides that provides extra moisture and strengthens the skin's barrier. This can absolutely be combined with Elixir Niactil 4% serum, as they both have different functions – Niactil 4% is known for its skin-renewing properties, and the peptide serum gives a good boost to skin health. When it comes to vitamin C serum (23%), it can be a bit more intense, so if you want to use both serums, it is recommended to apply them in layers – start with the vitamin C serum in the morning to get the best out of the antioxidant protection and then the peptide serum for extra moisture. 💧 Always remember to use sunscreen afterwards, as both vitamin C and AHA-like products can make the skin more sensitive to the sun.
