As a humectant, urea helps draw moisture from the air and from deep within the skin. This helps hydrate your skin. Studies show urea is an effective moisturizer for dry skin conditions. 40% urea is typical in medications for treating eczema and other skin conditions.
Urea has the strongest exfoliation effect in concentrations higher than 10%. It is a keratolytic agent, meaning it breaks down the keratin protein in the top layer of skin. This helps remove dead skin cells and flaking skin.
In medicine, urea has been shown to help increase the potency of other ingredients, such as fungal treatments.
Humans and animals use urea to metabolize nitrogen-containing compounds. Urea is highly soluble in water. Once dissolved, it is neither acidic nor alkaline.

It is a common ingredient in many products, especially those designed to hydrate skin. The primary benefits are retaining moisture, skin softening, and promoting a healthy skin barrier.

As an AHA, Citric Acid removes the top layer of skin cells from the newer layer of skin underneath. This helps skin to remove dark spots and even out skin tone.
If you spot Citric Acid near the end of an ingredient list, it's likely there as a pH adjuster rather than an active ingredient.

Ive used this for a whileee now.
First on my face, way too harsh so i did body only. I got lots of acne and heard nothing but "an all cure for everything skinwise" lol.
Well it HURTS like a bitch. God it stings.
Absolutely no difference, if anything worse skin issues. Around the buttocks area.
Best thing that couldve happened to me? African Black Soap.
This is great for exfoliation. This product is thin and watery which makes it a great product to use with a cotton pad. I use it as needed, by gently wiping my face with a soaked cotton square immediately after cleansing. I have also used this under my arms for discoloration & itching and on my feet.
The product is absorbed into the skin and leaves little to no residue.
