Star5 qty Amazing and potent
all...@ I will fully admit to being nervous about trying this one. 23% Vit C was more than I have used, ever. There was no need for worry. I’ve been using this nightly, & already seeing wonderful results. I store it in a cool place, follow all directions on the packaging. I was so impressed with the care taken in this packaging & in the detailed directions enclosed. Thank you Cosrx. That gave me comfort. I feel a slight tingle when I apply this sometimes (more so if I have exfoliated recently), it goes away quickly, & I’m left with a slight warmth on my skin. They truly were able to deliver a high potency Vitamin C serum, that does not have a negative effect on my skin. Much lighter weight than I expected, & absorbs so quickly. I started with just a couple drops, but have worked up to about 5 drops & no oily feeling at all.

Star4 qty Pretty good!
hel...@ I’ve been keeping my opened bottle in the fridge and using it every other morning. So far, I’ve noticed lightening of my freckles (yay!) and brighter looking skin. It feels a little sticky drying on the skin, which is a bummer to me.

Star5 qty Holy grail for 2022
ama...@ I don't usually rave about products, but I need to for this serum. It's the best vitamin C I have ever tried and is on my 2022 holy grail list. The texture is light and absorbs quickly into the skin. As a result, my pimple dark spots under my chin have been lightening. Also, the sunspots on my cheeks are less visible. Another fantastic thing I've noticed is that my forehead feels less dry and uneven. The vitamin c truly gives me a nice glow throughout the day. I received this product for free from @cosrx and @stylekorean_global for an honest review.

Star4 qty Vitamin C
man...@ Maximum effectiveness with minimum irritation! Highly concentrated, 23% pure vitamin C serum that fades acne scars and brightens complexion to revitalize dull and dry skin.⠀ Benefits: Fades acne scars & hyperpigmentation Brightens dull skin Diminishes fine line & wrinkles It is really interesting when I first opened this serum, It sounds like opening a soda! This should be really fresh Vitamin C serum! It is like a light weight fish oil texture! The smell is also like fish oil! The color of the serum also is golden color like oil! But it absorbed quickly when applied on the face! Not as heavy as I expect when I first test that texture on my hand! It is great to use with The Hyaluronic Acid! Not irritation!My skin has a bit of acne marks. I look forward to keep using it to reduce more of my acne marks!

Star5 qty I love this product
fol...@ COSRX Vitamin C serum has a slightly oily feel; not too thick, not too watery. It absorbs into my skin just as quickly as it is applied which is a huge bonus to me. I have previously used The Ordinary Ascorbic acid 8%+ Alpha Arbutin 2% which has a more oily texture and takes more time to absorb. I have a comparison right here if you’re curious. I noticed some tingling upon first application only. I have used this product every morning before my sunscreen since I have received it. I have noticed significant change in the overall brightness of my skin since incorporating this product into my routine. I loved the product so much that I already repurchased it.
