Scrub-Dub for Keratosis Pilaris
KP is keratin. Physical exfoliation is the answer.
Keratosis pilaris (the "chicken skin" bumps on upper arms, thighs, and butt) happens when keratin plugs hair follicles. The standard dermatology approach is gentle physical exfoliation paired with a keratolytic lotion. Loofahs are too aggressive for daily use, and washcloths don't reach the texture underneath.
The body side of Scrub-Dub is zinc-based antimicrobial TPE with soft cone bristles, firm enough to dislodge keratin plugs, gentle enough for everyday use. Pair with a lotion containing urea, lactic acid, or salicylic acid for best results.
Common questions
How long until I see smoother skin?
KP responds to consistency, not intensity. Most people see meaningful texture improvement after about 4 to 6 weeks of daily gentle exfoliation with Scrub-Dub paired with a keratolytic lotion. The bumps may not disappear entirely, KP is genetic for most people who have it, but they should flatten and the rough texture should soften noticeably.
Should I use it during a flare when the bumps are red and inflamed?
Yes, but lighter. KP redness comes from inflammation around the plugged follicles, and scrubbing harder only makes it worse. Use less pressure on red areas. The mechanical action still lifts loose keratin at the surface without irritating the follicle underneath.
What lotion should I pair it with?
Look for urea (10-20%), lactic acid (5-12%), or salicylic acid (2%) in the ingredients. AmLactin, CeraVe SA, and Eucerin Roughness Relief are common dermatologist recommendations. Apply to damp skin right after your shower, that's when absorption is best.
