How effective is chemical peel for sun spots?

Sun spots are areas of increased pigment associated with cumulative ultraviolet exposure. A peel can loosen some pigment in the outer skin and make colour look more even. It cannot confirm what a spot is, remove deeper pigment reliably, or prevent new spots from forming. Several factors shape the result, including spot depth, surrounding skin, treatment choice, and the way your skin heals.

A darker area after a peel may reflect temporary inflammation, while a changing spot may need medical examination rather than cosmetic lightening. A proper assessment comes before treating the visible colour.

Have the spots checked if they are new, changing, irregular, bleeding, itchy, painful, or persistently scaly. Tell your clinician about recent sun exposure, tanning, medicines, prior peels, and a history of dark marks after skin irritation. Follow the preparation plan, avoid picking or abrasive products, and protect the area from ultraviolet light while it recovers.

Seek medical review before a peel for a spot with an evolving border, uneven colour, bleeding, or a sore that does not heal. After treatment, contact the clinic for severe pain, blistering, spreading swelling, discharge, or a reaction that is more intense or prolonged than expected.

Are these spots suitable for cosmetic treatment? Do any need examination first? Will a peel reach the pigment involved? What aftercare reduces irritation and recurrence? How should I monitor the spots over time?
