First of all, this stuff smells awful! Like rotten eggs, I am going to hurl and then die disgusting! I am only using a little tiny bit once a day in the morning on a small spot on my face that I think is probably an acne scar. This product is working to erase the acne scar but the smell is so bad I can only stand a tiny bit without wanting to barf. And the smell lingers, ugh. Gross. 3 stars
