The best I've ever tried!
This vitamin C serum has been a game changer for me! (I have 34-year-old combination skin that is sensitive.) This gives me so much glow, a more even skin tone, and not to mention it's very economical to use. Tiny minus for the smell, but it disappears very quickly thankfully. I'm now on my second bottle and will never stop buying it🤩 (NB! Remember that this serum should be stored in the fridge!) #lykoreview8132 views- The comment was made 1 yearsThe serum might stay a little better in the fridge, but it will definitely oxidize. So there's no point in keeping it in the fridge. The product is therefore only good for 2 months.1 likes

Oxidizes quickly
After a few weeks, it has oxidized and turned completely brown and unusable.6997 views - The post was made 3 weeksRating: 5 out of 5verified customer
Great serum
Great vitamin C serum with real stuff. 23% ascorbic acid is a high concentration, and I use it with a bit of caution.1 product in post Great serum364 views - The post was made 3 weeks
No smell
My bottle did not have the smell that everyone mentions.1 product in post No smell337 views- The user's roll: Customer service at Lyko. The comment was made 3 weeksHi! This serum is fragrance-free, so it may have a very mild or barely noticeable scent due to its higher concentration of vitamin C, which can give a unique smell 🍊 The scent experience can also vary slightly between people and production batches, so if your bottle doesn’t have the smell others describe, it doesn’t necessarily mean something is wrong 😃 If you also notice other irregularities, you can file a complaint via My Pages and attach the batch number and clear pictures so the case can be reviewed more closely! All the best!

Vitamin C serum on the body?
Can this serum be used on other parts of the body besides just the face? Areas where you have pigmentation spots, etc. If so, what could be a better alternative?1 product in post Vitamin C serum on the body?1684 views- The user's roll: Customer service at Lyko. The comment was made 3 monthsHello! COSRX Advanced Snail 23 Serum 20 ml (Vitamin C 23%) can absolutely be used on other parts of the body where you have pigmentation spots, for example: hands, décolleté, shoulders, and smaller areas with sun spots. But if you want a product for larger areas, I recommend a product that is designed for the body. Here are some tips 👇 lyko.com/sv/the-inkey-list/the-inkey-list-pha-exfoliating-and-hydrating-body-water-cream-150-ml lyko.com/sv/niche-beauty-lab/niche-beauty-lab-transparent-lab-aha-smoothing-body-lotion-400-ml Good luck and all the best!1 likes

Hi, I'm going to try this for the first time. What do I do? Should I use it every day? And do you use it morning and night or?1 product in post New user2479 views- The user's roll: Customer service at Lyko. The comment was made 6 monthsHejsan!☺️ Oh, so fun that you’re going to try this! Start gently by using it 2-3 times a week in the evening on cleansed skin. Once your skin gets used to it, you can increase to every day and use it either morning or evening 🤍 Since it’s quite strong, it’s good to take it easy at first to avoid irritation🫧 All the best!

This highly concentrated serum with 23% pure vitamin C gives the skin a powerful glow boost and works effectively to lighten hyperpigmentation and even out skin tone. The formula is enriched with super vitamin E and hyaluronic acid, which together protect against oxidative stress and deeply hydrate for firmer and clearer skin.1 product in post Good2187 views- The post was made 7 monthsRating: 5 out of 5verified customer
🍋 love it
This is my favorite vitamin C. First of all, it’s pure ascorbic acid with the right pH – I’ve actually checked it on several bottles 😍 I started to see noticeable results after the second bottle, using it every morning. It evens out the skin tone very nicely and works as a strong antioxidant – it oxidizes in a way along with the free radicals. I can clearly tell that it has had a positive effect on the skin on my face. Especially, I see a more even skin tone and less visible wrinkles. It’s worth getting through the first period where the skin just has to get used to it.1 product in post 🍋 love it2616 views

Description
Ingredients
Use everyday like a daily vitamin for your skin!
A gentle vitamin C serum that is suitable on sensitive skin to use daily! Regular use will fade blemishes, dark spots and freckles and improve overall tone.
Keeping products with high contents of pure vitamin C refrigerated is the best way to keep the vitamin C fresh.
This serum does not contain any added perfume. As COSRX uses natural vitamin C, the product may have a slight, characteristic odor. This is completely normal and a sign that the vitamin is active. The odor will dissipate quickly after application. A slight fizzing sound may occur when the bottle is opened – this is due to natural gas formation from the active ingredients.
Use:
Cleanse your skin and put a toner. Then apply few drops of serum to the skin. User fingertips to gently massage and absorb the serum, starting from the inside of the face working towards the edges
