Proactiv

Does anyone over 20 use it?? If so what's your take on it?? I am 23 and for the past six months I've been getting bad pimple outbreaks I have never had them not even in my teen years I also get a bunch of blackheads on my nose I do use Neutrogena pink scrub to get rid of them seems to help but I still have blackheads left over that are stubborn. Nothing in my diet has changed or in my skincare routine or my make up routine so I am completely lost why I have so many black heads and pimples so I am wondering if this product is worth trying out. I also do not sleep with makeup on if it help and I have oily skin so I was my face twice to avoid acne.  No help lol.
