What should you know about patchy brown spots on skin?

Brown colour develops when skin makes or retains more melanin. It may remain after acne, Folliculitis, Pimples, shaving irritation or another rash has settled. Hormonal changes and sun exposure can deepen existing marks. Perioral Dermatitis, Rosacea and other inflammatory conditions may leave uneven colour after the active redness improves. The pattern, texture, location and timing matter: flat marks differ from scaly, raised, tender or bleeding lesions. A photograph and examination can help separate post-inflammatory pigment from a condition needing specific treatment.

Use gentle cleansing, moisturise, and avoid picking, scrubbing, bleaching mixtures or repeated friction over the area. Daily broad-spectrum sun protection and shade can reduce further darkening. Treating the active trigger is usually more useful than focusing only on colour; a clinician may discuss options after identifying whether the marks follow acne, shaving, hormones or another rash. LED Light Therapy is not a universal treatment for brown pigment, so ask what problem a proposed procedure is intended to address.

Book a dermatology assessment if a spot is new and unlike the others, changes in size, shape or colour, develops an irregular border, bleeds, crusts, becomes persistently itchy or does not heal. Seek earlier advice when pigmentation appears suddenly over a large area, follows a new medicine, or is accompanied by significant pain or blistering. Do not use a strong lightening product on broken or inflamed skin.

Does the pattern fit post-inflammatory pigmentation, acne-related marks or another diagnosis? Could a medicine, hormonal change or product be contributing? Which sunscreen and treatment suit my skin? What changes should prompt a prompt review?
