I used less of it than the size of a pea, reason being because I only have acne on my forehead (maybe because of
my hair?) and on
my nose (also the area around
my nose). It immediately dried
my face, it didn't peel or get red though.
I'll have to buy the 5%, and I'll quit using the 10%. Until then, I will be washing my face with a neutrogena soap I've been washing my face with for years.
