Amazon's bestselling body scrub is like a Magic Eraser for rough, bumpy skin — and it's on sale

What is it?

If you're someone who battles KP — keratosis pilaris — you're no stranger to the seemingly infinite number of scrubs, lotions and serums that claim to get rid of the bumps. I get it: I feel like I've tried every snake oil under the sun in search of something that doesn't irritate my skin and, ideally, actually works. When I stumbled upon this body scrub, I can't exactly say I had high hopes — but I was proven oh-so-very wrong. The First Aid Beauty KP Bump Eraser Body Scrub is like a Magic Eraser for your whole body.

This No. 1 bestseller is a miracle worker on bumps, flaky skin and those annoying red spots, shoppers say.

$20 at Amazon

Why is it a good deal?

This treatment for KP is just $20, but it's how long the product lasts that's really impressive. A tube of this stuff will last you ages; mine has been in my shower for over six months! I use it roughly once every 10 days after I shave — just squeeze out a pea-sized amount on your hands, and rub in where needed. It easily washes off, too.

Why do I need this?

The scrub is packed with pumice buffing beads that slough away dead skin and potent glycolic and lactic acids, which leave you bright and glowy. It's made with KP in mind, but it's excellent for butt acne (buttne), rough skin (think knees and elbows), ingrown hairs and on strawberry skin post-shave.

It's also rarely on sale — I bought my tube at full price! — so you'd better believe when I saw that Amazon had a 4 oz. version on sale for $20, I bought two extras to keep in my bathroom, for whenever I'm done with my current bottle. It doesn't have any strong scent, either, so it won't clash with the fragrance in your body wash.

What reviewers say

"I used this to get rid of bumps on my bikini line, and I wish I would've found this sooner!" shared a fan of the No. 1 bestselling body scrub. "Literally a miracle. My dark spots are disappearing, and that started happening maybe after three days of use. ... Definitely leaves my skin feeling like butter."

It doesn't take long to see results, either. Some shoppers noticed improvement after just one shower.

"I saw results with first use!" a shopper reported. "Wow, incredible product. So far, I’ve used it two days in a row and it has almost completely cleared my skin."

Another chimed in: "It works and I cried. My arms, from the shoulders to the wrist, are covered in KP. My legs all over, and my butt. Anyone who's here knows how much it ... can lower self-esteem. This. Is. The. Stuff. I have tried everything for over 15 years, and I cried because after the first use, it feels almost normal — a huge difference from how it's always been."

A final reviewer said: "If you need an exfoliant, this will do it. Just don’t put too much elbow [grease] into it. This is like cement-level friction."

This exfoliant employs alpha hydroxy acids to help fight keratosis pilaris, aka "chicken skin" or "strawberry skin."
