Exfoliation3 ingredients credited for this claimStrong support
“This supercharged formula is enriched with 10% AHA which works as a chemical exfoliant to help gently resurface the skin.”
This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: lactic acid.

“KP Smoothing Body Lotion Duo”
This product can help improve hydration of the skin with the two types of ingredients.
The first type is called “humectants”:
these ingredients help attract water.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from
within deeper layers of the skin. The following ingredients in this product do the job:
glycerin, lactic acid.
This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: caprylic/capric triglyceride, dimethicone.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: ceramide np, urea
Evens skin toneNot advertised by the brand · 3 ingredients credited for this claimStrong support
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: lactic acid
The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: glycyrrhiza glabra root extract.
Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.
Anti-agingNot advertised by the brand · 2 ingredients credited for this claimModerate support
This product contains lactic acid. This ingredient might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.

Product summary
Based on the ingredients included, "First Aid Beauty - KP Smoothing Body Lotion Duo" works well for moisturizing the skin. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. First Aid Beauty - KP Smoothing Body Lotion Duo ticks this box. Humectants in this product (urea, glycerin, lactic acid and sodium pca) help to increase the water content in the upper layer of the skin. (These ingredients do so by "capturing" water molecules from the outside air or from within the deeper layers of the skin). Ceramide np, caprylic/capric triglyceride, dimethicone, c12-15 alkyl benzoate and cetearyl alcohol in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.
Ingredient callouts
- As a plus, this moisturizer also contains ceramides (ceramide np 0.25% - 0.45% and ceramide np 0.45% - 0.70%). Ceramides are a type of lipids that our skin produces itself. They are a building block of the skin's barrier. Ceramides used in skincare are synthetic or extracted from plants. They work well for softening the skin surface and "patch holes" in the skin's barrier.
Irritation risk
