    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.

    Lovely product, gets a deduction for bad smell

    I've been using this for about a year now, very satisfied. The skin becomes soft and only needs light moisture on top.

    Question

    I am undergoing laser treatment for hair removal on my face, and I have recently started using the serum. Is this something that can be used even though I am having laser treatment?

    Pretty okay

    This vitamin C serum is pretty okay. It smells bad, leaves marks if you spill it, and separates often. It does the job it says it will.

    How long does it take to see results against hyperpigmentation?

      Hey Alva! It's not possible to say any specific timeframe as pigmentation is one of the hardest things to treat with home care - it depends on how deep they are and what the cause of them is. For some, vitamin C helps a lot (along with UV protection every day and not being in the sun with your face at all), but you have to be patient 🙏 Sometimes if it's hormonal, like contraception being the cause, they can disappear if you stop introducing the hormones. Hope it gets better for you 😎

    Oxidizes quickly

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

    Not the best!

    Leaves a smell. Had a breakout from the product. Recommend dermalogica's C-vitamin. It's milder.

    Smells bad

    I handle the smell just fine, but I understand that it can be a dealbreaker. For me, it absorbs nicely into the skin and is gentle enough for my sensitive skin.

    Hi! I use Elixir's Niactil 4% serum. Can this be combined with it? I also have darker circles around my eyes and have read that serums with vitamin C can help with this. Can I use this for dark circles around my eyes?

    If you’re going to buy something, let it be this. Perfect for pigment spots or unevenness. Works every time

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
