I am almost 30 years old and have had several white bumps on cheeks and around eyes that appear to be acne but never rupture and some have lasted for several years. I have tried to squeeze them, but nothing comes out and they do not disappear. I have tried all sorts of acne medicines, but nothing works... Ironically, I have no real problem with acne - only occasional pimple on chin or forehead. Anyway, these bumps are hard and very small (pin-head size) what are they and how can I get rid of them? Please help! Thank you!
