Sun exposure, acne scars, excessive oil production, hormonal shifts, friction, or irritation from harsh skin care products are frequent causes of darkened skin, black spots, and oily skin. Start with basic skin care: use a non-oily moisturiser, avoid scrubbing or squeezing pimples, and gently wash your face twice a day with a mild face wash designed for oily skin. Because sunshine can exacerbate pigmentation and black patches, wearing sunscreen every day is crucial. Without a dermatologist's advise, stay away from fairness or steroid creams as they can cause skin damage and eventually exacerbate pigmentation. See a dermatologist for a proper diagnosis and treatment alternatives, such as prescription creams, peels, or laser therapy, if the darkening is significant, spreading, irritating, or linked to acne scars.
