Some ways to get rid of dark spots caused by pimples include using natural home remedies, topical creams that contain glycolic or azelaic acid, chemical peels or skin lightening products. Some natural remedies that may be useful for hyperpigmentation from pimples include applying either potato slices or papaya pulp to the dark spots. While the potato acts as a natural bleaching agent, the papaya contains enzymes that help to diminish these marks.
There are topical creams that contain glycolic acid, which is an ingredient that promotes exfoliation of the outer skin layers. Azelaic acid is helpful not only for fading dark spots, but can also reduce inflammation and bacteria growth associated with acne flareups.
Chemical peels performed by a dermatologist involve applying a solution that may be glycolic acid or another substance for skin refinement. Similarly, a skin lightener that has hydroquinone or retinol is another treatment option for hyperpigmentation caused by pimples.
