Best Treatments for Keratosis Pilaris
Keratosis pilaris, often shortened to KP, is a very common and completely harmless condition caused by a build-up of keratin that blocks the hair follicles. The result is small, rough bumps, most often on the upper arms, thighs and buttocks, sometimes with a little redness. It cannot be cured outright, but the right routine can meaningfully smooth the bumps, soften the skin and keep the condition under control.
The most effective approach combines gentle exfoliation to loosen the keratin build-up with consistent hydration to soothe and support the skin. The products below have been chosen for their well-understood exfoliating and moisturising actives, offering a range of strengths so you can find something that suits your skin’s sensitivity.
Our Top Products for Keratosis Pilaris
Kaleidoscope Smoothing Body Serum
“Kaleidoscope is a body serum that is clinically proven to improve the appearance of keratosis pilaris, which makes it a natural starting point here. It combines shikimic acid and azelaic acid to gently refine texture with blueberry seed oil for antioxidant support, smoothing bumpy areas while hydrating rather than stripping the skin. In an independent trial it improved skin smoothness and softness and the appearance of KP over 42 days, and reduced transepidermal water loss. Vegan, cruelty-free, made in the UK and free from sulphates, parabens, microplastics and phthalates, it offers a gentle yet targeted way to manage KP.”
Transforming Body Lotion
“Practically synonymous with KP care in the UK, Ameliorate’s Transforming Body Lotion uses lactic acid and urea for gentle chemical exfoliation that loosens keratin plugs, alongside its LaH6 complex for hydration. It is a purpose-built, British Skin Foundation accredited choice that reliably smooths bumpy skin with regular use.”
SA Smoothing Cream
“Developed for dry, rough and bumpy skin, this cream combines salicylic acid and 10% urea to exfoliate with three essential ceramides to strengthen the barrier. It is an accessible, dermatologist-developed option that tackles the bumps while keeping the skin comfortable and hydrated.”
Skin Revealing Body Lotion with 10% AHA
“Built around 10% glycolic acid, this lotion helps dissolve the build-up of dead surface cells that contributes to KP, refining rough patches while hydrating shea butter keeps skin comfortable. It is a straightforward, effective exfoliating treatment for those who tolerate a higher acid strength.”
KP Bump Eraser Body Scrub with 10% AHA
“A KP specialist, this scrub combines a 10% AHA blend of glycolic and lactic acids with gentle physical exfoliating beads to lift dead skin and smooth bumps from two angles. Used a couple of times a week, it is a satisfying, targeted way to keep texture in check.”
Glycolic Acid 7% Exfoliating Toner
“A cult budget option, this 7% glycolic toner has become a popular KP hack, swiped over the arms and thighs to gently exfoliate and smooth rough texture. It is an affordable, effective way to add a regular exfoliating step, though it should be introduced gradually and patch tested first.”
UreaRepair Plus 10% Urea Lotion
“Urea is one of the most useful ingredients for KP because it both exfoliates and deeply hydrates. This lotion pairs 10% urea with lactate and ceramides to soften stubborn bumps and rough patches while supporting the skin barrier, making it a reliable daily option for smoother skin.”
Body Hydrating Cream
“A gentler choice, Dermalogica’s Body Hydrating Cream uses lactic acid and fruit-derived AHAs alongside hydrators to lightly exfoliate and calm KP-prone areas. It suits those who want a more moisturising, lower-strength treatment that still helps refine texture over time.”
Lipikar Baume AP+M
“KP-prone skin is often dry and easily irritated, and this soothing barrier balm helps on that front. With 20% shea butter, niacinamide and glycerin, it calms dryness and supports the barrier, making it an ideal partner to layer alongside an exfoliating treatment rather than a standalone fix for the bumps themselves.”
What ingredients help keratosis pilaris?
The most useful actives fall into two groups. Exfoliants do the work of clearing the keratin build-up: AHAs such as lactic and glycolic acid dissolve the bonds between dead surface cells, while the BHA salicylic acid penetrates into the follicle to help unclog it. Urea is particularly valuable because it both exfoliates and hydrates. Alongside these, humectants and barrier-supporting lipids like ceramides keep the skin soft and comfortable, which is essential because over-stripping KP-prone skin tends to make redness and irritation worse.
How often should you use these treatments?
Consistency is more important than intensity with KP. Hydrating lotions and creams can be used once or twice daily, while stronger exfoliating treatments such as acid scrubs or toners are best limited to one to three times a week depending on your skin’s sensitivity. Always follow exfoliation with a moisturiser to lock in hydration and support the barrier. Results build gradually, so a gentle, sustained routine will outperform aggressive over-exfoliation every time.
