super soft Best Vitamin C! - I am 20 years old, and this comes out to be the best vitamin C serum. Ive been using a cleanser and moisturizer but I needed to add a serum to my routine to help my skin stay youthful and this has helped give me glowy, hydrated, and smooth skin. I’ve used Bioelements, and it completely gave me a burning/tingle sensation on my skin. I have sensitive skin so I needed something that would be more gentle. I totally recommend this to anyone!
