I have raised bumps on my face , that have dark sunken centres. They look like tiny volcanos. They do not come to a head , and they do not go away. I use OTC anti acne remedies from Neutrogena, and talc free powder makeup. I am 51 and am peri menopausal; I had regular acne as a teen and when I was pregnant , but hardly any in the past 20 years. Might this be a different kind of acne? If so, how do I treat it?
