COSRXThe Vitamin C 13 Serum

So far, I'm very positive about it. It absorbs great.

It brightens the skin, improves skin tone, reduces discoloration, and is non-sticky. Remember to store it in the refrigerator.

The serum brightens the skin nicely. It has a slightly peculiar aroma that goes away after a while. The serum is a bit sticky on the face. It should be stored in the refrigerator.

I didn't expect such good results and I was very pleased with this serum. I'm waiting for it to be available to buy again.

Some people wrote that it smelled bad, but I really liked the scent! :) It reminded me of bread (?) anyway, it was only more noticeable the first few times. I recommend it :)

It is true that the serum smells a little, but that is simply what ascorbic acid does, you have to take that into account. It is important to store it in the refrigerator after opening so that it does not oxidize. The packaging is also appropriate, since you should not put too much vitamin C on your face. I use it several times a week and I see the results, my skin is not as tired, red and looks healthier overall. I have also noticed an improvement in fine wrinkles.

Very runny and slightly smelly. I was surprised by it. I can't say I'm thrilled with it, but it doesn't irritate me in any way either.

It doesn't stick at all, it does what it's supposed to do 10/10

Results are visible after the first use and it absorbs quickly, but unfortunately the quantity is very small for the price.

One of the best serums I've tried. It gives a perfect glow and texture and creates that super glass skin. I highly recommend it. I think it should not be missing from any routine!!!!
