What they liked

  • Dual chemical and physical exfoliation
  • Grit is effective but not sharp or cutting
  • Fragrance-free and gentle for sensitive skin

What they flagged

  • Too harsh for delicate areas like underarms
  • Scrub breaks up and balls on skin
  • Requires consistent weekly use to see results

What the gurus are saying

This scrub earns consistent praise for its particular grit (buffing effectively without feeling sharp or stripping) and its dual chemical and physical exfoliation approach. Most gurus use it one to two times weekly in the shower, often after hot water has softened skin, and many report it helps prevent ingrown hairs. The catch: it's densely concentrated and intense, so those with very sensitive skin or low tolerance for scrubbing may find it borderline too much, and it belongs on the body only, never the face, where the physical texture risks micro-tears especially for breakout-prone skin.

"I've been talking about this product for years and I still use it because it does a really good job to improve skin texture. If you have any dryness or flakiness on your legs, or you have keratosis pilaris, those bumps that can form behind your thighs or the backs of your arms, this product is exceptional. It's the First Aid Beauty KP Bump Eraser, the body scrub that contains 10% AHA, glycolic and lactic acid, so it has a nice grit to it, like a pumice. I really love this for my chest specifically because sometimes in the summer I get a little bit of roughness there, and [...] if you self tan and still have some self tanner lingering on your body, this on its own does a really good job of getting rid of that. It just sloughs everything off and gives a really nice smooth canvas to the skin. I like to do this maybe once a week, sometimes two or three times a week if my skin is really dry or I have a lot of bumps. It's [...] fragrance free, which I feel is good for those who are more on the sensitive side since it's quite gentle, but because it is like a pumice and a little rough, maybe start with a little amount and see how it feels on your skin. [...] I really love using this even on my hands when my knuckles are a little dry, and on my heels, [...] especially during the winter but even in the summer. It's just a really great product to exfoliate."

"I've been using the KP Bump Eraser by First Aid Beauty so this is a body scrub but I also use this on my hands as well. Make sure your hands are wet, just put the littlest amount of this onto your hands and then just gently go in circular motions all over, and then I will do that for probably a couple of minutes and then once that's done I will leave it on my hands for a couple of minutes to allow those AHAs to do its thing and then I rinse off with cold water. I will do this maybe every other day, sometimes in the morning or sometimes I will do it at night time, but this really works and I love it."

"The one that I have repurchased the most by far is the KP Bump Eraser from First Aid Beauty. Although they market this for KP, which is keratosis pilaris, sort of the chicken skin that people can get on their upper arms or on their thighs and buttocks, I use this on my skin everywhere. I think the reason I keep going back to this one so much is that the grit in there is just so particular. It's very gritty, but it's not sharp. So I get a lot of incredible buffing when I use it. I do like small circular motions over my whole body, but my skin doesn't feel irritated or stripped when I'm done with it. Also, this formula is not just physical exfoliation. It has alpha hydroxy acids and beta hydroxy acid, salicylic acid in there. So you're getting this dual chemical and physical exfoliation. I use this in the shower one to two times a week. And I actually like to do my exfoliation towards the end of my shower once the hot water has been on my skin and helped soften up the cells a little bit so that they just exfoliate off much easier. And I'm pretty generous with this. Like I'll squeeze a lot out of the tube because I want it to feel like a full spa experience. And I always use it on a day that I'm going to shave because it helps remove some of those surface dead skin cells so they don't clog my hair follicles and make me more likely to get ingrown hair."

Skincare Mistakes I Will NEVER Make Again as a Derm | Dr. Sam Ellis
"My favorite is probably the First Aid Beauty KP Bump Eraser. It's got some alpha hydroxy acids in there in addition to the physical exfoliation, but I find that it just makes my skin and my booty so smooth and it prevents ingrown hairs like that has been tried and true for me for so many years."
How to Shower Like a Dermatologist for Your Smoothest Skin Ever | Dr. Sam Ellis
"The one that I reach for over and over and over again because it makes my skin so smooth is the First Aid Beauty KP Bump Eraser. It's got a good sized solid grit to it but the grit isn't sharp. I've found in other body exfoliants sometimes the little particles themselves are sharp like I've cut myself on them before, and it also has alpha hydroxy acids in it which is chemical exfoliation so you're getting a dual action exfoliation, the physical and the chemical. It's so satisfying to have that instantly soft smooth skin. I think the KP Bump Eraser is too rough for use in more delicate areas like the genital region or the armpits so I recommend using a little exfoliating mitt for prepping those areas for shaving."
Dermatologist Explains Keratosis Pilaris (KP): Affordable Drugstore Treatments to Try!
"The First Aid Beauty KP Bump Eraser has 10 AHA, it's a blend of glycolic acid and lactic acid, and this is more of a scrub that you can use in the shower. I find that my teens tend to be more adherent with this KP product than anything else, and I think it's partially because they like that physical exfoliation. They feel like they're really doing something, and they are. If you're using a physical exfoliation like a scrub as part of your KP treatment method, it is super important to follow that up with a good body moisturizer."

Dermatologist Answers Your Most Asked Questions
"I've been struggling with keratosis pilaris on the upper arms for 3 years now. I've been to two dermatologists and they both basically said my current regimen is the proper way to treat it, but it doesn't really seem to help. Currently, I use the First Aid Beauty KP Bump Eraser Body Scrub with 10% AHA one to two times a week due to it being a much harsher scrub."

"First Aid Beauty, also a Sephora brand. I am a fan of a lot of their products. They make great products that are targeted toward keratosis pilaris, which is an issue we see a lot in the derm practice. So, I do recommend First Aid Beauty products often to my patients. I also love their ingrown hair peel pads, which is great for people with ingrown hair. So, use alongside a retinoid. I'm also a big fan of their radiance peel pads. I think that those are gentle and are great exfoliant for people who want something to improve texture, hyperpigmentation, but don't want anything too harsh. Huge fan. The price point's not terrible."

"First Aid Beauty sent me their KP body eraser bump scrub. It's not that bad. Compared to my favorite from Kopari, this feels slightly under that in terms of physical exfoliation, but it's still really good. It has ten percent AHA, which I use on my body exclusively since AHA is too much for my face."

"This combines both chemical and physical exfoliation for a gentle but effective formula. If you're looking for a formula that's going to chemically dissolve keratin but also gently buff out that top of the skin, this is a good one to try. It combines physical and chemical exfoliation to smooth that rough bumpy skin. It uses glycolic and lactic acid at a combined level of 10% AHA to dissolve the keratin plug while those fine pumice beads provide gentle physical exfoliation."

"The KP Bump Eraser from First Aid Beauty is really densely loaded with pumice, has a toothpaste sort of texture, and is just really thick and really intense as a scrub. [...] I have a very low tolerance when it comes to beauty products, so this one is actually borderline too much for me. [...] My biggest tip here for KP is that you do need to really be consistent with exfoliating. You can't just try to overload yourself on one day and then hope that that will last for two weeks."
~Nay
"The KP Bump Eraser from First Aid Beauty, [...] I liked it for a while until I discovered the scrub from Narium, and this one is just very rough. [...] The scrubbies in it, [...] it's just a little too harsh for my skin. It's very easy to overdo it and end up actually scratching yourself, especially in more sensitive areas like around your underarms. And it's less of a cream sort of formula, so it balls up and falls off the skin pretty easily. It has 10% AHA, it's fine, but it's not my first choice. I much prefer the Narium one."

Um I'm sorry but I'm obsessed with these
"I loved the First Aid Beauty KP [...] Bump Eraser, the body scrub that has AHA and BHA. I had been using that forever. I don't really get KP bumps, I get a little bit sometimes like right here on my arm, very annoying, but when I use that scrub we get nothing, skin nice and exfoliated and healthy. I usually use it like one or two times a week. [...] The First Aid Beauty one is a little bit more gritty, it's like kind of a gray color, a little bit more gritty. It [...] kind of breaks up a little bit which I don't love."

"First Aid Beauty KP Bump Eraser Body Scrub with 10% AHA is something that I would only recommend that you use on the body but not the face because it does feel a little bit scrubby. It has pumice buffing beads, it's borderline physical. Your body can tolerate this but never your face. Some people might think it's a great dupe to use as a physical exfoliant for the face, but the reality is you do not want to do that, especially if you are prone to breakouts on your face, because your face is more sensitive and you'll get micro tears and you'll make the breakouts more inflamed and you'll get worsening of your scars. If you have KP, which is non-inflamed growth around your hair follicles around your arms and your legs, [...] you can use this to help to buff it. [...] Let it sit on your skin so that the acid can work its magic and then work on buffing it before you wash it off. Make sure your skin gets skin time with it."

"First Aid Beauty KP Bump Eraser Body Scrub [...] with 10% Alpha hydroxy acids, which are basically glycolic acid or lactic acid. [...] This one feels like sand at the beach. I would not use this on your face at all because you do not want to get micro tears that can lead to furthering worsening of your inflammation, but on the body our skin is much thicker and able to tolerate it."

"This product is actually really nice and I'm recommending it because it's more gentle compared to some of the other scrubs that I have used or have seen in the past. It's marketed for helping with body bumps, keratosis pilaris, and in general, [...] if you use this regularly by removing and scrubbing away the dead skin buildup it can help because dead skin is what clogs up the hair follicles and leads to those bumps. For individuals that [...] have mild KP or have strawberry legs, certainly using this as long as you're gentle, and this product overall is pretty gentle, is not going to inflame your skin and make it worse."

~Mixed
"This is one of the brand's best-selling products and is currently 28 dollars. This is considered a physical exfoliant body scrub because it contains pumice buffing beads. You will use this in the shower and wash it off. This focuses on the key ingredients of lactic acid and glycolic acid, which is what will be doing the smoothing work. The specific percentage of each of these is not listed, though the package says it's a combined 10 percent. This is not super helpful; I'd prefer the breakdown listed instead. It does contain a longer list of ingredients with added extracts aimed to soothe and nourish the skin, and people really seem to love this product in general. However, I am not overly impressed with this particular ingredients list."
~Yay
"For a body care treat I'm going in for the First Aid Beauty KP Bump Eraser Body Scrub. This uses glycolic and lactic acid at 10% to help exfoliate the skin, but it also has some scrubbies in it which is great for my rough elbows and knees."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Alpha hydroxy acids

Alpha hydroxy acids loosen the bonds holding dead cells at the surface. The evidence supports smoother texture and more even tone over time, and they can leave skin more sensitive to sun.

Vitamin E

Vitamin E is an antioxidant, and it is often in a formula to keep the other ingredients stable rather than as the active itself. It pairs well with vitamin C, though on its own the evidence for visible change is limited.
