What should you know about hyperpigmentation sun damage?

Ultraviolet light signals pigment-making cells to produce more melanin. Existing spots can become more noticeable, and repeated exposure may bring back colour after it has faded. Pigment can also follow irritation from a sunburn, rash, or cosmetic procedure. It commonly appears on the face, hands, shoulders, chest, and other uncovered areas.

Not every dark patch is caused by sunlight. A clinician may consider its shape, surface, distribution, medicines, hormones, and any preceding inflammation. A new or changing spot should be examined before using a lightening treatment.

Use shade, protective clothing, a hat, and broad-spectrum sunscreen on exposed skin; reapply as directed when outdoors. Choose gentle, fragrance-free products and avoid picking or aggressive exfoliation. A dermatologist may recommend a tailored topical medicine, Skin Brightening Treatment, Chemical Peel, IPL Photofacial, or picosecond laser treatment. Treatment choice depends on pigment depth, skin tone, sensitivity, and whether the cause is still active.

Book a review for a patch that changes quickly, develops an irregular border, bleeds, crusts, becomes persistently itchy or painful, or looks unlike your other marks. Seek care for blistering or severe swelling after sun exposure, and pause cosmetic treatment if the skin becomes raw or inflamed.

Ask whether the pattern fits sun-related pigment, whether a medication or rash is contributing, which sunscreen texture you are likely to use consistently, and when a procedure would be appropriate. Ask how to prevent irritation and what changes should prompt reassessment.
