I have very oily skin at 31 years old. But I do not break out on my forehead or cheeks. I only break out once a month or two with one or two deep cystic pimples on my chin or lip. Some months I am completely clear. I am male. Could this be hormonal acne? If so, what can I take to treat it? My diet isn't the best, but I don't think there's a direct link between diet and acne for me because some months Im completely clear.
