Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.
So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Stay hydrated!
Learn more about WaterGlycerin is already naturally found in your skin. It helps moisturize and protect your skin.
A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.
As a humectant, it helps the skin stay hydrated by pulling moisture to your skin. The low molecular weight of glycerin allows it to pull moisture into the deeper layers of your skin.
Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.
Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.
In cosmetics, glycerin is usually derived from plants such as soybean or palm. However, it can also be sourced from animals, such as tallow or animal fat.
This ingredient is organic, colorless, odorless, and non-toxic.
Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.
Learn more about GlycerinCaprylyl Glycol is a humectant and emollient, meaning it attracts and preserves moisture.
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.
Though Caprylyl Glycol is an alcohol derived from fatty acids, it is not the kind that can dry out skin.
This ingredient is also used as a preservative to extend the life of products. It has slight antimicrobial properties.
Learn more about Caprylyl GlycolGlucose is a simple sugar and is the most important source of energy in all organisms.
In skincare, glucose is used to hydrate the skin. It also acts as a prebiotic for our natural biome.
Glucose is hydrating due to its humectant property. As a humectant, glucose draws moisture from the air and from deeper levels in the skin.
Our skin contains many sugars that act as prebiotics and help strengthen our natural microbiome. Having a healthy microbiome helps protect our skin from harmful bacteria and other contaminants.
Studies show glucose may help with fading discoloration and pigmentation. This is because our skin metabolizes glucose into lactic acid. Lactic acid is an AHA that helps exfoliate the top layer of skin.

I used this to correct the skin color of my sunburnt shoulders and back. It felt drying when using it but this product combined with physical exfoliation using a brush loofah removed my tan lines and reverted my skin color to how it was from childhood. Some of my scar marks from a long time ago also disappeared after using this.
A very hydrating moisturizer and sunscreen are required after Show more
Effective dark spots corrector soap but remember it can be drying and causes sun sensitivity, so always use moisturizer(night) and sunscreen(morning) after using this soap because if not you will get the opposite result that you want from this product .

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.
