Q: I recently noticed small, whitish bumps on my forehead; what are they, and how can I get rid of them?

A: If each bump has what looks like a dilated pore in the center, you probably have sebaceous hyperplasia (enlarged oil glands), says Deborah S. Sarnoff, MD, clinical professor of dermatology at New York University Medical Center. These bumps are very common and usually develop in people over 40. And, from the Things Could Be Worse department: They are benign and treatable. A doctor can cauterize the pores with an electric needle; the cauterization melts the oil gland and a scab forms, which falls off in a week or less. (Doesn't hurt, and it worked for me.) Or she can apply a clear chemical solution to be absorbed by the oil glands, and then activate the solution with a laser treatment, which shrinks the pores.
