Treatments for pigmentation remove dark patches and uneven skin tone caused by excess melanin. Hydroquinone, retinoids, and vitamin C treatments diminish pigmentation over months. Chemical peels, laser therapy, and strong pulsed light treatments aggressively target pigmented cells to regenerate skin. However, these methods may aggravate pigmentation or cause negative effects. Sunscreens and oral antioxidant supplements combat oxidation and UV exposure, which causes pigmentation. To find the best treatment, consult a dermatologist.
