“It usually starts in your late 20s or early 30s and then progresses. Although all skin types may develop it, types III through IV can have the most difficult time camouflaging the robust pigment that develops,” Dr. Guanche says.
Some studies suggest other potential causes or associations, including thyroid disease and genetic influences, according to Lisa Guidry Pruett, M.D., a dermatologist with U.S. Dermatology Partners, Carrollton, Texas.
