Keratosis pilaris in legs

Leg keratosis pilaris may appear as clusters of tiny bumps around hair follicles, with a sandpaper-like feel. Dry skin, tight clothing, waxing, or frequent shaving can make the area more irritated. Ingrown hairs are separate lesions in which a hair grows back into the skin, although both problems can occur after hair removal.

The pattern often matters more than a single bump. Skin bumps that are painful, filled with pus, or arranged in a spreading rash should be assessed rather than assumed to be keratosis pilaris.

Apply an emollient after bathing while the skin is still slightly damp. A product with urea, lactic acid, or salicylic acid can help loosen surface scale; begin slowly and avoid applying it to cuts or freshly shaved skin. Choose loose clothing, reduce friction, and resist picking at individual follicles.

Persistent texture may lead to a discussion about topical retinoids or a chemical peel. If shaving or unwanted hair repeatedly aggravates follicles, laser hair removal may be considered after a clinician reviews your skin and hair pattern.

Arrange an examination for sudden onset, marked pain, warmth, pus, crusting, severe itch, or rapid spread. Get prompt medical help if swelling is accompanied by fever or you feel unwell. Review is also useful when the bumps do not match the usual follicular pattern or do not settle with consistent gentle care.

Ask whether the bumps are keratosis pilaris, folliculitis, or ingrown hairs; which emollient and exfoliating ingredient to try; and how to time products around shaving or waxing. Discuss topical retinoids if the texture is persistent and mention any history of irritation or pigment change.
