Pure Vitamin C 23% Serum with Vitamin E & Hyaluronic Acid, Brightening & Hydrating Facial Serum for Fine Lines, Uneven Skin Tone & Dull Skin, Korean Skincare, 0.7oz/20g

I’ve used two bottles of this! After a month of using, 50% of my 25 year old hyperpigmentation went away. Been using it consistently since December. Most of the pigmentation has vanished including areas like lips on which I don’t put the product. My 10 years old scars have vanished by 90%. Still using it as there’s 30% of pigmentation left on my chin and neck. Amazing product. Huge fan of this brand. Use their snail serum and the formulation for pores.

5-Star Review: The COSRX Vitamin C23 serum is an absolute powerhouse! Packed with Vitamin E and hyaluronic acid, it has transformed my skin. As someone with Indian skin living in the UK, I’ve struggled to find a serum that absorbs well, but this one works beautifully. It sinks right in, leaving my skin hydrated, radiant, and noticeably improved. Yes, there’s a slight smell when you first apply it, but it fades almost instantly. Honestly, it’s a small trade-off for the incredible results. My skin feels smoother, more even-toned, and healthier overall. I’m just loving it and can’t recommend it enough!

This is my favorite Vitamin C serum! I’ve already finished one bottle and just started my second. Initially, I was hesitant because of its slightly oily texture—I was worried it might make my skin feel greasier. However, I was pleasantly surprised by the radiant glow it gave me, and the slight stickiness actually helped my foundation adhere better. Overall, my skin looks and feels much healthier. The only downside is the scent, but it’s not strong enough to stop me from using it.

My skin is like a champ, it can handle anything! I’ve tried countless creams, and nothing has ever bothered it. But after just two days of using this vitamin c , Corsx day cream and corsx snail serum, my skin is in a terrible state. It’s super dry, itchy, and peeling. I’ve got red patches all over my face, and it looks like I’ve been through a chemical burn. *****UPDATE***** COSRX customer service reached out to me with a sincere apology, eager to resolve my issue. They even offered a full refund! Even though their products aren’t my cup of tea, I’m giving them a big 5* for their exceptional customer service. Thanks a bunch!

Has a bit of a funny smell, but it works

I think its working to reduce my pigmentation on my cheeks, however….. i camt bring myself to re-buy this product. The colour, the texture and the smell is like urine! To the point myself and my boyfriend have actually debated whether we got a dud bottle thats been tampered with and someone has pee-d in it as some kind of sick joke!! Im using it every morning as i do think its working, i dont want to waste my money, and i have faith in the human race that there isnt some strange employee working for the company that has pulled some sick joke….but its defo not a pleasant experience!! I cant stress enough how much it feels as though you are rubbing urine all over your face!

I'm 48 and a major skincare addict and the ordinary skincare range changed my skin like no other. I wanted to find a good vitamin c serum but after trying lots of different brands I just never got the glow or the results I was craving for, that's until I trued this little gem. I use some really strong actives so my skin is used to strong products so I would definitely not reccomend this for sensitive skin or skin that is not used to strong products but if your looking for a vitamin c serum that gives amazing results I highly highly 100 percent reccomend this 1. I have just subscribed so I never run out . 1 of my favourite skincare products ever . There is also a lower 13% serum from thus brand that I would reccomend if your skin is not used to using strong active products tho I have nit tried that personally so cannot give an honest review of that but as its from cosrx I'm sure it will still be an aging product as most of their products are in my experience.

This product actually does works. Had a dark patch around lips n chin are and it did visibly reduce just in few days. Qorks very well with dry skin.
