This is THE BEST vitamin C serum I’ve ever used. It never becomes discolored and is very high quality. I love Kossma beauty!
I bought the vitamin c serum to help with redness on my face and it’s definitely helping. It also feels so good on my skin - silky but doesn’t leave it greasy.
Loving the serum so far. My skin feels smoother and I love all the.Kossma products so far😊
I just love this serum so much! There is nothing like this in the world! Only 3 ingredients, no fragrance or essential oils, no toxic anything and IT WORKS! Believe the hype! My skin has never been healthier on Kossma.
Been using this product for about a week or so. Don’t think my skin likes it. Looks like it is breaking out 😩😩
