Purely C

I’ve had angry red spots on my chest for several years now and gave up on even trying to get rid of them. Within a month of using this serum, they’re gone!! My face also has a much more even complexion, I feel so much more confident without makeup. Thank you, Kossma Beauty.!!

My Skin LOVES This Serum!

After switching from squalane oil (from a different company) to this serum, I can't believe how much my skin has changed. My acne is nearly completely gone, my scars are fading, and my dry patches are nowhere to be seen. I seriously can't believe it. I only bought one to try it out, and I'll definitely be buying about 10 more. Seriously, highly recommended!

So far so good. Only been using a few weeks and no shocking improvements but I definitely need to give it more time. Over all though, using Kossma products my skin is more hydrated.
