كوسركس - سيروم فيتامين سي 13 سيروم الوجه (20g)

I have extremely dry/dehydrated skin with a decent amount of acne scarring and dark spots from sun damage from when I was younger. I've been using this for months now and I noticed a drastic difference in as little as weeks. Now, my skin is SO much clearer and even than it was in years, probably not this clear since I was a child. I can't recommend this enough it immediately makes my skin glowy and plump and it ACTUALLY works unlike other Vitamin C/brightening products. 20/10 GET IT

[This review was collected as part of a promotion.] This product is so good! The shipment took a while but the product feels really hydrating. I would suggest using it in the morning after using a cleanser. If you have to step out in the sun, it also gels well with your sunscreen. 10/10 recommended!

[This review was collected as part of a promotion.] This is so soft and even on the skin. Does feel a bit sticky towards the end of application but if you let it dry into the skin that goes away. The scent is different, I won’t lie, but doesn’t linger post application. I have noticed lightening in my melasma since starting CosRx products, but I am using multiple products, so most likely from the combination of all. Great size bottle for the price. It is only 13% pure vitamin C, but it is helping with brightness.

I have sensitive, mature normal skin and I've had some pretty bad vit c reactions to the ordinary and good molecules. I gave my skin a 6 week break and started using this 2 weeks ago. I was afraid so I was using it every 3 days and I had no reaction. My skin does look brighter, I have tried to use this daytime and nighttime and I like the results from either. When I have to be up very early I do my day routine at night so I don't skip it rushing in the morning. I'm very happy with this and will repurchase. I can see you only need a small amount, one dropper is plenty for my face neck and chest

[This review was collected as part of a promotion.] I recently incorporated Vitamin C into my skincare routine, and I'm loving the results. I apply it both morning and night on a slightly damp face for better absorption. Right after the Vitamin C serum, I use Cosrx's Niacinamide 15, and the combination works wonders! Thank you, Cosrx!

[This review was collected as part of a promotion.] Haven’t received jaw dropping results yet but my face looks a bit brighter. Kind of smells like meat. I layer this with my other cosrx products and looks very dewy afterwards. I hope to remove off of my dark spots but we can’t have it all can we.

[This review was collected as part of a promotion.] I love this vitamin c its not to strong and don't cause my a reaction on my skin it a perfect fit for me I already see a improvement in the brightness and evenness of my Skin its working great for me and I will be buying it again

[This review was collected as part of a promotion.] I love how clean and simple cosrx product formulas are so naturally when looking to add vitamin c to my routine, I had to try their serum. I knew their more concentrated vitamin c serum would likely be too much for my skin so I gave this one a go. At first I loved how glowy it made me, especially when using in my daytime routine before my snail mucin essence, but eventually I noticed that it was leaving me spotty, almost like the start of a rash or a bad reaction. I do have very sensitive skin so I don’t necessarily blame the product, I’m honestly accepting that straight up vitamin c might just not be fit for my skin type, which is okay just disappointing. I’d love to try any creams cosrx may create in the future that include vitamin c rather than center on it, but until then I’ve just cut it from my routine, no harm no foul. As soon as I stopped using it, I stopped seeing a problem in my skin after my daytime routine and it didn’t leave any lasting damage, but other sensitive skin types should be aware in case they start to see the same results while using it
