About this item
- Why Moisturizer Alone Never Worked: KP bumps are keratin buildup around the hair follicle. Moisturizer softens the surface — it doesn't lift the buildup. 10% AHAs + PHAs loosen it and hydrated silica sweeps it away, helping improve the look of keratosis pilaris, chicken skin, strawberry skin and dry, rough bumps on arms, legs and thighs.
- Smooth In The Shower, Clearer Over Weeks: Skin feels smoother from the first rinse, and the look of dry, rough bumps keeps improving with regular use. Use 1-2 times a week. Smooth arms — sleeves optional.
- The Original KP Duty, Since 1998: The cult-classic body scrub created by board-certified dermatologist Dr. Audrey Kunin, more than two decades before competing KP brands existed. Chemical + physical exfoliation in one — glycolic, lactic, gluconolactone and lactobionic acids with hydrated silica. Formulated and filled in the USA.
- Also For Ingrown Hairs And Razor Bumps: Use before shaving to help reduce the look of ingrown hairs and post-shave bumps, and before self-tanner for a more even finish. Helps improve the look of dullness and uneven body texture. Body only — not for the face.
- No Fragrance, No Pumice: The physical exfoliant is hydrated silica, not pumice, and PHAs are larger molecules that absorb more slowly — exfoliation without the harshness. Synthetic fragrance free, sulfate-free and dermatologist-tested. Evening primrose, borage and black currant seed oils condition as you exfoliate. Suitable for skin prone to sensitivity; not recommended for ultra-sensitive skin.
- 30-Day Money-Back Guarantee: Not right for your skin? Return it within 30 days under Amazon's returns policy. DERMAdoctor has stood behind KP Duty since 1998. Pair with KP Duty Body Lotion for the full routine.

Smooth Bumpy Skin with DERMAdoctor Is it too harsh for sensitive skin? It's dermatologist-formulated to be gentle: the blend pairs AHAs with PHAs — larger molecules known for being gentler on skin prone to sensitivity — plus conditioning botanical oils. Start 1x per week and increase as tolerated. Does it help with the redness or just the bumps? Many customers use it for both. The 10% AHA + PHA blend helps improve the look of redness as well as rough, bumpy texture. Results vary; use consistently 1-2x per week. Does this have a fragrance or scent? No. The current formula is fragrance-free and unscented — no added synthetic fragrance. Any faint natural scent comes from the botanical seed oils in the formula. How long until I see smoother-looking skin? Many customers notice softer-feeling skin after the first use. Apply to dry skin before showering, 1-2x per week — most see visible improvement in the look of bumpy texture within 2-4 weeks. Ongoing use keeps skin looking its best. How long does one jar last? A little goes a long way — most customers use a small amount 1-2x per week, so a jar typically lasts several months
