What should you know about melasma sun damage?

Light can stimulate pigment-producing cells, while heat and inflammation may add to the problem. This means a person may notice darker patches after outdoor time, travel, driving, or repeated heat even without a painful sunburn. Melasma often forms a fairly even pattern across the face, whereas a single rough or bleeding spot may point to another sun-related condition and needs examination.

Apply broad-spectrum sunscreen as directed and reapply when appropriate for your activity. Use shade, a wide-brimmed hat, sunglasses, and physical barriers when outdoors. A tinted product may be useful when visible light is a concern. Keep skincare gentle and avoid tanning, scrubbing, and home peels. If pigment persists, a clinician may discuss skin brightening treatment, chemical peel, microneedling, or laser toning with suitable preparation and aftercare.

Have a changing patch checked if it becomes rough, scaly, sore, crusted, swollen, or bleeds, especially when it is confined to one area. Seek prompt care for a lesion that does not heal or for a strong reaction after treatment. A review can separate melasma from other effects of sun-damaged skin and guide the next step.

Could visible light or heat be affecting my pigmentation? Which protection should I use for my routine? Is a procedure appropriate now, and how can I lower the chance of irritation afterward?
