    Unbelievably effective🤩

    This is definitely one of the most effective home products I have used so far🤩. I have dry skin and a combination skin where I am starting to see signs of aging. Additionally, I have acne scars that I have learned to live with, but I am excited if I can get rid of them😅. Here are a few pluses first; 👍 evens out skin tone and surface 👍 Is economical, a few drops are enough 👍 The scent is not very strong in my opinion (although it usually doesn't bother me😆) 👍 A slight tingling on the skin (when I started using it, it felt like that for a while) I think it's nice to notice concretely that the product works.... Of course, sometimes it can mean something completely different🙈, but in this case, it meant effectiveness😁 I added even more effectiveness after some time of use by spraying rose water before the product and on damp skin I added the serum. And something I might have noticed if you want to try the product😇 ~KEEP THE PRODUCT IN THE CABINET! I confirmed this with customer service when I couldn't find it mentioned after the purchase. I saw that the effects remained in the product. ~Since the product is effective, it can also dry out, so it's good to have a moisturizing serum etc. in use every other day, or that's what I did to avoid dry skin ~The shelf life is stated to be 2 months 😐, and I think that's really little... But I understand that this ensures the product's 'effect' and I understand that they are indicative. (The Candy Day blog has a good article on shelf life if you're interested). All in all, I noticed after a couple of weeks that my skin was better in tone. I also received compliments and questions at work about what I have done since my skin is glowing 🤭😁. So I can warmly recommend🤗 Do you have experiences with similar products? What would you recommend? As someone who wants to try, it would be nice to try something different again🤭 P.s. sorry that there is no before picture 🥹 #cosrx #lykoreview #vitaminc

    Fermented?

    It’s possible I got a faulty product, but every time I opened it, air came out, as if the liquid was fermenting inside the bottle. Smelled weird and did little for my skin. #lykoreview

      Hey Astrid 💌 Thank you so much for your feedback 💛 It sounds like your product is actually behaving as it should 😊 When it comes to purified vitamin C serums: 🍊 The vitamin C ingredients activate when the product gets a certain color – orange/yellow is normal. 💨 The “puff” sound upon opening is intentional and shows that the bottle is sealed according to safety instructions. 👃 The smell may be perceived as a bit strong or “natural”, sometimes like fish oil – this is completely normal. ❄️ Tip: Store vitamin C in the refrigerator for best shelf life and effect. If the color, however, turns dark brown or the product feels fermented, it may indicate that something has happened to the product. Then you can contact us, and we will look into options for exchange or return 💌 Have a lovely day ahead!

    Lighten scars

    Hey ☺️ I have a scar from a belly button piercing that has gotten darker than my skin, can I use this serum to lighten it? I see several say it helps with scars

      Hey Marie 👋🏼 Thanks for your question. COSRX The Vitamin C 23 Serum is known for its brightening properties, and many have used it to even out skin tone and reduce the visibility of scars. The serum contains 23% stabilized vitamin C, which can help lighten darker areas on the skin. Important to note: Concentration: The high concentration of vitamin C can be strong for sensitive skin. It is recommended to start with a lower concentration, such as 13%, to see how your skin reacts. Usage: Apply the serum to clean skin after toner, and use it in the evening. Avoid direct sunlight after application, and use sunscreen in the morning to protect your skin. Storage: To prevent oxidation and maintain the product's effectiveness, store the serum in a cool place and use it within 2 months after opening. If you have sensitive skin or are unsure how the product will affect you, it may be wise to consult a dermatologist before use. Have a lovely day ahead💞

    Seems like a solid product, but

    the product doesn't smell good and the product is also so runny that it tends to run right through the dropper, causing the serum to drip everywhere. Other than that, I haven't experienced any side effects or negative results.

    The Product's Scent

    Hi! I bought this serum almost a month ago, and I opened it the very next day. When I opened it, it hissed, like there was pressure or gas in the bottle. Additionally, the product smells very strong, the scent reminds me of kombucha, so it smells a bit old and bad. The color is yellow as it should be. Is this normal, or has the product already gone bad in storage? I have used it, though, and my skin hasn't reacted in any way.

      Hey Eve! ✨ Both the bottle's spray and the strong smell are characteristics of this product 😊

    Love love love!

    Works so well on my skin! I've struggled for a long time to get rid of spots from pimples, and after I tried vitamin C, there are no spots left! Absolutely amazing, I regret not trying this earlier!😍😍😍

      Hi Lene! This works well for most skin types🤗 Since you feel dry and tight in your face after showering, this is a sign that you lack moisture, so it’s great if you add a moisturizing serum or other hydrating products! Have a nice day😎

      Hey, so great that you’re asking 😍 When using Epiduo, it’s important to avoid combining it with other active ingredients like retinol, vitamin C, and other acids. This can lead to skin irritation and can delay the healing of scars after acne ⬇️ Feel free to use a mild moisturizing serum to counteract the drying effect Epiduo has 👇 lyko.com/no/cosrx/cosrx-the-hyaluronic-acid-3-serum-20-ml lyko.com/no/the-ordinary/the-ordinary-hyaluronic-acid-2-b5 Also, always remember to use sunscreen during the day to prevent pigmentation after acne ☀️ Wishing you a wonderful day ahead 🌱
