    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!) #lykoreview

      The 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.

    Oxidizes quickly

    After a few weeks, it has oxidized and turned completely brown and unusable.

    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?

    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?

      Hejsan!☺️ 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!

    Good

    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.

    🍋 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.

    Really good but poor packaging

    Really good and effective in itself. I have bought it several times but it goes bad every time before I get to use it. I use the serum every morning but still it gets too old before I have used it up. A new airtight packaging would be nice. I would rather pay extra for packaging than throw away 1/4.

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

20 ml
