Rated 4 out of 5 by from Smells divine and leaves a Smells divine and leaves a dewy glow. I am new to vitamin C but the product is gentle enough to not irritate my skin - this is important for me as I am also using retinol. However, unfortunately the serum leaks out of the applicator when taken out of the bottle, resulting in wastage. Aside from that, the product is great!
