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

When?
Should this be used before or after beplain chamomile ph-balanced toner?Translated from norwegian
57 views- Customer service at Lyko3 daysHey 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!1 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 likes130 views- 4 daysThanks 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.1 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
1496 views- Customer service at Lyko1 monthHi! 😊 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.

Like it a lot
I really like this product. After using it for 5 months, I can actually see a difference in my face. The booster gives a feeling of moisture and a nice tightening of the skin. The peptides in the serum really work – I notice it both on my face and my hands (I always rub the leftovers on my hands). The product also gives a glow that lasts a long time. With regular use, it helps with wrinkles, brightens the skin a bit, moisturizes, and provides nourishment. It works excellently with other serums, toners, and creams.Translated from norwegian

Can you use these two at the same time?
Hi! I wonder if you can use these two products at the same time? 🔺COSRX The Alpha-Arbutin 2 Discoloration Care Serum 🔺COSRX The 6 Peptide Skin Booster If you can't use them at the same time, can you use one in the morning and one in the evening? If so, which one should I use in the morning and which one should I use in the evening? Have a nice weekend! Best, HelenaTranslated from swedish
1500 views- Customer service at Lyko1 monthHey Helena! 👋🤍 Yes, you can use both products, but it's best to split them up in your routine to maximize the effect and reduce the risk of irritation 💃 My best tip 👇 In the morning, use the Peptide Skin Booster, which helps with hydration, elasticity, and strengthening the skin barrier, making it perfect for the day. Follow up with a moisturizing cream and sunscreen (SPF is a must!) 😉☀️ In the evening, use Alpha-Arbutin, which works to even out skin tone and reduce pigmentation, making it perfect for the night when the skin recovers. Apply after cleansing and follow up with a moisturizer 💧🌛 Take care and good luck with your new products 🥰2 likes
