First Aid Beauty KP Bump Eraser Body Scrub: What to Know About the 10% AHA Exfoliator

If you’ve noticed small, rough bumps on the backs of your arms or thighs, you’re not alone. That texture is often a sign of keratosis pilaris — sometimes called “strawberry skin” or “chicken skin” — a common and harmless condition where keratin builds up around hair follicles. First Aid Beauty’s KP Bump Eraser Body Scrub is one of the products formulated specifically to target that rough texture, and it has become a regular fixture in a lot of body-care routines.

What it is

The KP Bump Eraser is a two-in-one body scrub that combines physical and chemical exfoliation. Pumice buffs away surface buildup, while a 10% blend of alpha hydroxy acids — glycolic and lactic — works to loosen the dead skin cells that can leave skin feeling rough. According to First Aid Beauty, it’s designed to smooth and soften skin with regular use. The version covered here is the 2-ounce size.

How to use it

Exfoliating acids tend to work best with consistent, moderate use rather than aggressive scrubbing. The brand suggests massaging a small amount onto damp skin in the shower a few times a week, rinsing, and following with a moisturizer. As with any AHA product, it’s worth introducing it gradually — and using sunscreen on exposed skin, since acids can increase sun sensitivity.

Who it’s for

It’s aimed at anyone dealing with rough, bumpy, or dry patches, most commonly on the arms, thighs, and shoulders. People with very sensitive or compromised skin may want to patch test first or check with a dermatologist, since 10% AHA is a relatively active concentration for a body product.
