What should you know about vitamin A for KP?

Keratosis pilaris causes small, rough follicular bumps, often on the upper arms, thighs, cheeks, or buttocks. The plugs are made from keratin around hair follicles. They are usually a texture concern rather than a sign of infection, but redness or itch can occur.

Topical retinoids, a form of vitamin A, can encourage more orderly shedding inside the follicle. They may help texture over time, yet they can cause dryness, stinging, and peeling. White bumps around the eyes may instead be [Milia](/conditions/milia/), which need different handling.

Apply the prescribed product sparingly to dry skin and begin at the advised frequency. Follow with a fragrance-free moisturiser, avoid vigorous scrubbing, and give the skin time to adjust. A gentle cleanser and regular moisturising often matter as much as the active ingredient.

Do not pick or squeeze the bumps. If the diagnosis is uncertain, a clinician can compare the pattern with [Skin Bumps](/symptoms/skin-bumps/) or [Whiteheads](/symptoms/whiteheads/). A [Topical Retinoids](/treatments/medical-dermatology/topical-retinoids/) plan should be reviewed if irritation persists.

Seek review if the bumps become painful, pus-filled, suddenly widespread, intensely itchy, or associated with swelling. A rash that changes quickly may not be keratosis pilaris and should not be treated by increasing vitamin A on your own.

Ask whether the pattern is keratosis pilaris, how often to use the product, which moisturiser suits your skin, and whether another option is preferable for sensitive areas.
