Literally makes my skin glow. I always always get the comment wow your skin is glowing when I put this on. No burning, no weird smell, feels like water almost.
While I was happy with the Vit C serum I’ve been using for years, I decided to try this brand and it’s now my new favorite! It is on the thin side but spreads nicely. The smell is very pleasant. I notice my skin looks smoother and brighter. Glad I made the switch and plan to continue with this brand.
Very impressive for the price point! It absorbs very well, doesn’t leave any film, greasy feeling or anything behind. My skin immediately felt soft and smooth. I used it after cleansing and toning and before moisturizer. It also smells really nice which was an unexpected bonus.
It absorbs quickly, layers well under moisturizers, and causes no irritation.
After a couple days of using this twice daily I noticed results. My chin, which is usually covered in tiny bumps has gotten significantly smoother, and my skin just looks and feels smoother. I have somewhat sensitive skin and this does not irritate at all. I'm very happy with this product.
