It can occur after microdermbrasion, Fraxel Restore or Repair, carbon dioxide, erbium yag, alexandrite, ruby and neodynium-yag lasers, as well as dermabrasion and chemical peels. The condition is more common in slighlty darker individuals. Many people who are prone to this note they get dark after bumping themselves, or a small grease burn in the kitchen, or curling iron, or acne blemishes that turn brown. Lightening creams that are prescribed along with chemical peels can help lighten this color shold it occur. Sunscreen is important after the procedure to minimize the potential of the sun's rays to exacerbate or trigger the problem.
