First Aid Beauty KP Bump Eraser Body Scrub Review

KP Bump Eraser Body Scrub by First Aid Beauty is a scrub that contains pumice as a physical exfoliant and 10% glycolic and lactic acids as chemical exfoliants. This is safe for all skin types and is fragrance-free. This claims that the AHAs loosen the top layer of skin and decongest pores, while the pumice sweeps it away, helping improve rough, dry bumps and dry skin, revealing smooth, healthy-looking skin. Despite this product being called KP Bump Eraser, this makes no claims on nor mentions keratosis pilaris on the packaging or website.

Ingredients: Pumice, Water/Aqua/Eau, Glycolic Acid, Sodium Cocoyl Isethionate, Lactic Acid, Dimethicone, Stearic Acid, Cetearyl Alcohol, Sodium Hydroxide, Palmitic Acid, Glycerin, C12-15 Alkyl Benzoate, Sorbitol, Colloidal Oatmeal, Tocopherol, Chrysanthemum Parthenium (Feverfew) Extract, Camellia Sinensis Leaf Extract, Glycyrrhiza Glabra (Licorice) Root Extract, Salix Nigra (Willow) Bark Extract, Bisabolol, Hydrogenated Coconut Acid, Xanthan Gum, Steareth-20, Steareth-21, Myristic Acid, Sodium Isethionate, Phenoxyethanol, Potassium Sorbate, Sodium Benzoate, Leuconostoc/Radish Root Ferment Filtrate, EDTA.

Bisabolol and colloidal oatmeal soothe the skin. Feverfew and licorice root can help red irritated skin.

Directions: Using one to two times a week, apply to wet skin and massage on affected areas. Rinse and pat dry. Follow with a moisturizer. Do not use on the face.

Keratosis pilaris is the result of a buildup of keratin that clogs the opening of the hair follicles and causes bumpy, rough skin, often affecting the upper arms, thighs, buttocks or cheeks. KP is also called chicken skin or strawberry skin. There is no cure or preventative, but the skin can be made to look better by exfoliating and moisturizing.

I have had KP on my upper legs and upper arms and small pimples and whiteheads on my chest for the last 10 or so years and bought KP Bump Eraser in hopes of smoothing and improving the appearance of my skin. I used once a week for a month and then twice a week for the remaining 2-1/2 months. After massaging, I let this sit on my skin for a couple minutes while washing my hair to get the benefit of the AHAs, and followed with a moisturizer.

The product has fine-grain pumice that is not irritating when massaging on the skin. It has a mildly acidic scent. This rinses off well in the shower.

From the first use, my skin felt very smooth. I use sugar scrubs regularly and while my skin feels smooth, the KP Bump Eraser works so much better to exfoliate the skin because unlike sugar, pumice does not dissolve in water so it can be scrubbed for longer. My arms had some improvement in overall skin tone and smoothness of the bumps. I was hoping for more improvement for the breakouts on my chest. My legs, being the most affected, had the most improvement in redness and overall appearance of the bumpy skin (the worse the skin is, the more noticeable the improvement will be). My shins are often quite dry and this sloughed off the dry skin.

I wonder how much the AHAs in the scrub have an effect on the skin, being a rinse-off product, and if I would get the same results without the addition of the chemical exfoliant. I’ve just purchased the Skin Smoothing Body Lotion with 10% AHA from Reversa to see if I get further improvement.

With First Aid Beauty’s KP Bump Eraser, the smoothness of the skin is very good, the look of dry skin is improved, overall skin tone is a bit better and bumps are generally improved. I would repurchase.

Thank you for reading.

  1. Thank you so much for the review! I’m looking for a product that could help with my KP, it looks pretty much the same as your before photos, sometimes it’s a bit worse though. Have you tried any other products?


    1. I’ve been using Reversa skin smoothing body lotion for a week or two now. It has 10% glycolic acid and has improved the bumps on my arms and legs. They’re not gone, but look and feel smoother so far. I also use a boar bristle dry brush before showering.


  2. Hi Michele, did anything work to help improve beyond your “after” photo? My legs are currently at your “after” photo and this is just after 1.5 months of using Cerave Salicylic Acid lotion daily. However, I seem to have reached a plato =(


    1. Hi. I tried the Reversa Body Smoothing Lotion with 10% glycolic acid. This helped a bit on the legs (not so much that I’d buy it again for my legs) but worked really well on my shoulders. However a glycolic lotion may help you.
      I’m thinking of trying either Retin-Oil or the glycolic toner next (both by Deciem and both apparently improving texture).


  3. Hi Michele! I can’t tell from the pictures, but did you notice a huge difference on your chest? I’ve dealt with bumps on my chest for a long time and I’m starting to wonder if it is KP.


    1. Hi. There wasn’t much, if any, improvement on my chest; I’m not sure if mine is KP or not, it looks different than the bumps on my arms and legs. For my chest I’ve been using the Murad clarifying body spray (I’ll post that review on Sunday) but not much improvement with that either, and for the last week, I’ve been using the glycolic toner from The Ordindary and hoping that will help.
