Prime Day Deal: First Aid Beauty’s KP Bump Eraser Body Scrub (4 oz) Is 30% Off

Brit+Co Staff on June 16, 2026

If you deal with “strawberry skin” — those small, rough bumps on the arms and thighs — Prime Day is a good time to stock up. First Aid Beauty’s KP Bump Eraser Body Scrub, one of the most recommended products for keratosis pilaris, is 30% off for Amazon Prime Day, running Tuesday, June 23 through Friday, June 26, 2026. Those bumps come from a common, harmless buildup of keratin around hair follicles, and this scrub is formulated specifically to smooth that texture.

The deal

For Prime Day only — June 23–26, 2026 — the 4 oz KP Bump Eraser is 30% off on Amazon. Prime Day pricing requires a Prime membership, and deal prices typically end when the event closes on June 26 (or earlier if it sells out). The 4 oz is a nice middle-ground size — more than the travel size but easy to use up — so the discount is a good chance to grab it.

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 leave skin feeling rough. According to First Aid Beauty, it’s designed to smooth and soften skin with regular use. This is the 4 oz size.

How to use it

Exfoliating acids 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, introduce it gradually and use 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 on the arms, thighs, and shoulders — and the 4 oz size is a flexible pick whether you’re newer to the scrub or want a manageable amount on hand. 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.
