Using AHA for keratosis pilaris

Lactic acid and glycolic acid are alpha hydroxy acids that help shed compacted surface cells. Improvement tends to depend on continued, tolerable care; the bumps may return when treatment stops.

Keratosis pilaris develops when keratin collects around hair-follicle openings. It often feels like fine sandpaper on the upper arms, thighs, cheeks, or buttocks and may look more noticeable when skin is dry.

These bumps can resemble ingrown hairs or other follicular conditions, but they do not need squeezing. An AHA loosens the surface plug; an emollient reduces dryness and supports the skin barrier. Neither approach changes the underlying tendency to form the plugs.

Apply a low-irritation AHA lotion as directed to intact skin, starting less often than the maximum label frequency. Follow with a fragrance-free cream or ointment, particularly after bathing. Use lukewarm water and a mild cleanser instead of long hot showers.

Skip abrasive gloves and forceful scrubbing, which can increase redness without clearing the follicle. Pause the acid after shaving or waxing if the area stings, and protect exposed treated areas with broad-spectrum sunscreen. Do not layer a retinoid, peel, or another acid until a clinician confirms the combination is suitable.

Discontinue the AHA if the skin becomes raw, swollen, blistered, or persistently painful. Seek prompt care for rapidly spreading redness, warmth, pus, fever, or significant tenderness because these features can accompany infection rather than uncomplicated keratosis pilaris.

Book a routine assessment if the diagnosis is uncertain, itching disrupts sleep, dark marks are developing, or careful home treatment has not helped. A dermatologist may suggest a different keratolytic, emollient therapy, or a topical retinoid after examining the skin.

Bring the product or ingredient list and ask whether the bumps fit keratosis pilaris, how often to apply the acid, and which moisturiser can reduce dryness. Also mention sensitive skin, eczema, current hair-removal methods, and any retinoid or exfoliant already in your routine.
