First Aid Beauty's KP Bump Eraser combines pumice buffing beads with 10% AHA from glycolic and lactic acids to exfoliate rough, bumpy skin associated with keratosis pilaris, alongside colloidal oatmeal and soothing botanical extracts. The original version lists no fragrance, and FAB directs using it in the shower once or twice a week. Creators report smoother legs and arms after long-term use, and FAB recently refreshed the packaging with minimal formula updates. At $30 for 8 oz, it costs more than drugstore KP options.

r/SkincareAddiction

2x per week in the shower: Use KP Bump Eraser. Rub it into the red bumpy areas and let soak in for about 2 minutes before rinsing off … After about a year of this I don't even have to use the bump erasure anymore!

Ouai leave in conditioner and first aid beauty bump eraser. That size lasts me a whole year.

FAQ

Good questions.

How often should I use the KP Bump Eraser?

FAB directs using it in the shower once or twice a week. Because it combines pumice with 10% AHA, more frequent use is not part of the brand's directions.

Is the KP Bump Eraser fragrance-free?

The original KP Bump Eraser lists no fragrance in its ingredients, and FAB says its formulas contain no artificial fragrance. FAB also sells scented versions, including Fresh Peach, Fresh Strawberry and Toasted Coconut.

Did the formula change?

FAB's product images say it refreshed the packaging and made minimal formula updates to meet evolving retailer clean standards. The current ingredient list still pairs pumice with glycolic and lactic acids.

Can it get rid of keratosis pilaris?

FAB designs it to reduce the appearance of KP bumps and roughness, and 92% of KP panelists in its 38-person consumer test said skin felt exceptionally smooth after 10 days. It smooths the look and feel of bumps rather than curing the condition.
