COSRX Pure Vitamin C 23% Serum with Vitamin E & Hyaluronic Acid, Hydrating Facial Serum for Fine Lines, Uneven Skin Tone & Dull Skin, 0.7oz/20g, Korean Skin Care, Stocking stuffers for women

Instant Glow
I’ve only used this product for a few days, but I can already tell a difference, which is crazy. As soon as I put it on, it gave me an instant glow—not oily, greasy mess kind of glow, but the healthy, plump kind of glow. As someone who had beautiful skin during pregnancy, but is now struggling with uneven and dull skin tone postpartum, this made me extremely happy. Anyway, here are my initial thoughts:Formulation:•this contains a high ascorbic acid percentage. I’ve never been sensitive to ascorbic acid, so my skin does well with the high concentration. However, if you have more sensitive skin, consider starting with their other vitamin c serum that has a lower percentage of vitamin c.•there is no ferulic acid present, which is generally used to stabilize ascorbic acid. Without this, I’m afraid the product won’t last terribly long without oxidizing, so keep this in mind. The instructions do say to refrigerate after opening, which may help slow down oxidation.Texture:The texture of this serum reminds me of a bi-fácil product where there is an oil layer and water layer that need a little shake to incorporate. Don’t let the oiliness scare you though, it does sink in to the skin well and doesn’t feel heavy on the skin. I haven’t had any issues with pilling when I’ve applied other products and makeup on top.Smell:As many reviewers have mentioned, it does have a particular smell to it. To me, it reminds me of tuna, which is quite unpleasant. However, it does dissipitate quickly. I just hold my breath while I apply it to my face XD I don’t smell it at all throughout the day.

Happy with it, very good formula
First time with this brand, but using Vit C serum for years.So far one of my favorites in the range of price. Smells uncomfortable fishy but that is the Vit C normal smell, after some seconds over the skin the smell is gone, and personally prefer this than any extra essence. The oil is pretty thin and absorbs immediately. Haven’t had any reactions but I have quite of time with this VitC concentration. I like how my skin looks, give me a glossy renewed look every morning. Any result with dark spots or fine lines, but I realized that is normal aging and nothing to do with it lol, anyway my skin looks healthy and younger for my age. Totally happy with this brand in my second week of use.Update: one month of use and still love it!

Much to my surprise!
I’ve been back and forth with skin care for years. From pricey brands to more affordable brands. My last purchase of vitamin c serum was from skinceuticals. Super expensive and although it was ok it certainly isn’t worth the price. I use the snail mucin from cosrx and I really like it, so I decided to try the vitamin c 13 from cosrx. They also have a vitamin c 23, but I wanted to try the 13 first. Like many of the reviews mention it does have a “fishy” smell to it, but it doesn’t last for long. I’m on the 5th day of using this and I can’t believe it. I can see a difference. My skin is brighter and softer in just a few days. I’ve never with any other skin product have seen results so quickly. I do believe I’ve finally found a good vitamin c serum that I’m gonna stick with and like I mentioned this is the 13%. When this is gone, I’ll order the 23%. I do recommend starting with the 13% to avoid any skin irritation and then move up to the 23%. I am a little bummed out because it took me a long time and alot of money before I was able to find cosrx, but now that I found it, I’ll continue to use it. I highly recommend and shout out to cosrx for making awesome skin care products affordable. 🌟🌟🌟🌟🌟

Could cause acne
I’ve been a huge fan of Cosrx products. I originally had used the lower strength of vitamin c and upgraded to this one a few months back. I feel that it does work in terms of discoloration, but for some reason this one makes me break out more than other vitamin c products I’ve used. I’m going to finish up what I have left of this bottle but I think I’ll go back to the lower strength. My only complaint with the Cosrx vitamin c is how small the bottles are. It could be because vitamin c doesn’t last long in terms of potency once opened, but it’s a bit pricey for such a small bottle. You definitely have to keep it in the fridge and the smell is strange and not very pleasant but goes away shortly after application. I have not noticed any stinging or irritation from this higher strength vitamin c, but like I said, I have noticed acne break outs happening a bit more than before. My recommendation…give it a shot if you’ve already used the lower strength and feel you need more potency, but beware of potential break outs.

Lo he estado usando junto con la niacinamida de la misma marca y me encanta cómo deja mi piel hidratada y con mis poros más chicos, llevo 1 mes usando este combo.

Very good product well worth the money and very fast delivery
