Thanks doctor. I will schedule an appointment with a dermatologist just to make sure its not something serious. I appreciate the feedback.And post a follow up after see the doctor.
Bumps that come and go would not be either allergy or sun damage.. They're probably just clogged pores, the grownup equivalent of pimples. But the only way you're going to know for sure what they are is to have a doctor look at them. So don't worry about these bumps--see a doctor and check. Meantime, no treatment is needed, but be sure to avoid picking or rubbing any of the bumps.
Best.
