What supplements have evidence for keratosis pilaris?

Very limited supplement evidence exists specifically for keratosis pilaris (KP). Vitamin A may support normal keratinization. Omega-3 fatty acids and vitamin D have theoretical benefit for the inflammatory component. KP is primarily managed topically with exfoliating agents (urea, lactic acid, salicylic acid) and emollients rather than oral supplements.

Can supplements alone treat keratosis pilaris?

Supplements alone are unlikely to resolve KP. This condition is caused by keratin plugging hair follicles and is primarily genetic. Topical keratolytics (urea 20–40%, lactic acid 12%, salicylic acid), regular moisturization, and gentle exfoliation are the evidence-based management approaches. KP often improves with age naturally.

When should someone with keratosis pilaris see a dermatologist?

See a dermatologist if KP is extensive, inflamed, bothersome, or not responding to OTC treatments after 3 months. A dermatologist can prescribe stronger topical retinoids or keratolytics and rule out other conditions that may mimic KP, such as follicular eczema or lichen spinulosus.
