Milia, Skin Tags and Seborrheic Keratosis
Milia are small, bump-like cysts found under the skin. They are usually 1 to 2 millimeters (mm) in size. Milia most often appear on the face, commonly around the eyelids and cheeks, though they can occur anywhere. They are formed when keratin becomes trapped under the skin.
Skin tags can appear smooth or irregular, and may attach to the skin by a short, narrow stalk called a “peduncle.” Doctors don’t know for certain what causes tags but skin rubbing against skin may play a role, since the growths usually occur among skin folds — in the armpits, neck and groin, and sometimes on eyelids.
Seborrheic keratoses are benign skin growths that some people develop as they age. They often appear on the back or chest, but can occur on any part of the body. Seborrheic keratoses grow slowly, in groups or singly. Most people will develop at least one seborrheic keratosis during their lifetime.
