Seborrheic keratoses (SKs) โ€” raised growths that look a bit like irregular, waxy moles or warts โ€” affect as many as 83 million Americans, according to one 2015 study. That would make it more common than acne, rosacea and psoriasisโ€ฆcombined.

For something so common, we don’t really know what causes the growths that can appear on the face, neck, back, chest, and stomach, according to the American Academy of Dermatology.
