What should you know about cod liver oil keratosis pilaris?

Keratosis pilaris happens when keratin builds up around hair follicles, producing small rough bumps, often on the upper arms, thighs, cheeks, or buttocks. The bumps may look red or skin-coloured and can feel dry. Cod liver oil cannot be relied on to clear this follicular plugging, and taking a supplement may carry concerns related to ingredients, interactions, or excess vitamin intake.

This condition is different from [Ingrown Hairs](/symptoms/ingrown-hairs/) and other causes of [Skin Bumps](/symptoms/skin-bumps/). A clinician can check the diagnosis when bumps are painful, pus-filled, rapidly changing, or unlike your usual pattern.

Apply a bland moisturiser regularly, especially after bathing, and avoid harsh scrubbing, picking, or very hot water. Products containing keratolytic ingredients may soften the plugs; a clinician can help select an option suited to sensitive skin. [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) is a useful starting point, while [Topical Retinoids](/treatments/medical-dermatology/topical-retinoids/) may be considered for some people.

If texture or redness remains troublesome, discuss [Chemical Peel](/treatments/aesthetic-procedures/chemical-peel/) or [Laser Hair Removal](/treatments/laser-and-energy/laser-hair-removal/) only after confirming the diagnosis and skin type. Stop any product that causes marked burning, swelling, or a persistent rash.

Arrange a dermatology review if the bumps are tender, itchy enough to disturb sleep, draining, scar-like, or spreading quickly. Seek prompt care for fever, rapidly increasing warmth and redness, or facial swelling. A new rash should not be assumed to be keratosis pilaris simply because it feels rough.

Does this look like keratosis pilaris or another follicle problem? Would a supplement add value or create interaction concerns? Which moisturiser or active ingredient should I try, how often, and when should I stop?
