DERMAdoctor KP Bump Eraser Keratosis Pilaris Lotion, 8 oz — 10% AHA/PHA Exfoliating & Hydrating, Fragrance-Free

DERMAdoctor KP Bump Eraser is a dermatologist-formulated body lotion that gently exfoliates keratosis pilaris (KP) while delivering lasting hydration to smooth rough, bumpy skin.

This therapeutic lotion pairs chemical exfoliants with barrier-replenishing hydrators to tackle the texture of KP on arms, thighs, and other body areas. The formula combines glycolic and lactic acids (AHAs) with polyhydroxy acids (PHAs) and moisturizing ingredients like ceramides, urea, and squalane to soften plugs, calm redness, and lock in moisture without added fragrance. It’s presented in an 8 oz bottle designed for daily use on sensitive, dry, or mature skin types seeking a non-comedogenic routine.

How does this lotion improve the feel of bumpy skin?

The lotion uses a dual exfoliating approach—fast-acting AHAs to dissolve surface buildup and gentler PHAs to help lift stubborn plugs—so skin feels smoother over time. Regular application reduces roughness and helps skin texture look more even without physical scrubs.

• 10% combined AHA/PHA concentration for progressive exfoliation
• Glycolic and lactic acids target texture; PHAs provide gentle resurfacing
• Non-abrasive lotion format suitable for daily body use

What hydration and barrier-support benefits does it offer?

Alongside exfoliants, the formula includes ceramides, urea, and squalane to restore and seal the skin barrier. These moisturizers replenish lipids and attract water to the skin, limiting dryness and maintaining smoother results between treatments.

• Ceramides help rebuild the skin’s protective lipid layer
• Urea provides humectant benefits for continuous hydration
• Squalane offers lightweight emollience for soft, non-greasy skin

Is this product suitable for sensitive or acne-prone skin?

DERMAdoctor KP Bump Eraser is formulated to be gentle yet effective: it’s fragrance-free and non-comedogenic, designed to minimize irritation while addressing KP and rough patches. Users with sensitive or acne-prone skin should start slowly—apply every other day and increase frequency as tolerated.

• Fragrance-free and non-comedogenic to reduce irritation and breakouts
• Safe for dry, sensitive, and mature skin when used as directed
• Recommended gradual introduction to monitor tolerance

How should I use it in my body care routine?

Apply the lotion to clean, dry skin once daily or as advised by a dermatologist, concentrating on areas with bumps or rough patches. For best consistency, integrate it into evening routines and pair with sunscreen during daytime use since exfoliation can increase sun sensitivity.

• Use on arms, legs, thighs, and other affected body areas
• Begin with every-other-day application, then progress to daily as tolerated
• Follow with sunscreen on exposed areas when used in daytime

Who is this for: DERMAdoctor KP Bump Eraser is intended for anyone seeking a clinically minded body treatment for keratosis pilaris and persistent rough patches—especially people who want a lotion that combines effective chemical exfoliation with barrier-restoring hydration. It suits those preferring fragrance-free, non-comedogenic products and users ready to introduce a targeted exfoliating step into their body-care routine. If you have pronounced sensitivity, are using prescription topical treatments, or have concerns, consult a dermatologist before beginning any new exfoliating product.
