What should you know about dark spots from chafing?

Rubbing, heat, sweat, and moisture can weaken the skin barrier. The area may first feel sore, sting, look red, or develop tiny breaks; darker colour can remain after inflammation settles. Common sites include the inner thighs, underarms, groin, and beneath skin folds. If the patch is scaly, sharply bordered, very itchy, or spreading, consider other possibilities such as [Tinea Versicolor](/conditions/tinea-versicolor/) or seek an examination.

Gently wash and pat the area dry, then choose loose, breathable clothing that limits repeated contact. A bland moisturiser or barrier product may reduce friction when appropriate for the site; stop if it stings or causes a rash. Avoid scrubbing, picking, fragranced products, and attempting to lighten recently irritated skin. Once the skin is calm, a clinician can discuss options such as [Skin Brightening Treatment](/treatments/aesthetic-procedures/skin-brightening-treatment/) if colour remains.

Arrange medical review if pain, redness, warmth, swelling, cracks, pus, bad odour, or fever develops, or if the area does not improve after friction is reduced. Get advice when a patch repeatedly returns, spreads beyond the rubbing zone, or affects walking, exercise, or sleep. Broken skin can need treatment for inflammation or infection.

Does this look like post-inflammatory pigmentation from friction, or could it be dermatitis or infection? Which barrier product is suitable for this body site? When would a peel or other treatment be safe to consider?
