Dear user, pigmentation is your normal skin-color, whereas hyperpigmentation is darker skin tone and hypopigmentation is lighter skin tone. Hyperpigmentation treatment has various options such as creams, face acids, retinoids, chemical peels, laser peel, intense pulse light therapy, dermabrasion and microdermabrasion, they are prescribed depending on the extent to which your skin could be dark. They get rid of darkness and provide exfoliating benefits in some cases, and can hide scars, spots and sun damage too. Hypopigmentation treatment on another hand includes options such as dermabrasion, chemical peel, laser resurfacing and lightening gels, but you may require other kinds of treatment if at all there's some underlying cause behind this. Since this cannot be treated at home, therefore an experienced dermatologist would be your best guide. For more information, visit best dermatologists in India.
