Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:
- It is a solvent, meaning that it helps to dissolve other ingredients. This also enhances the absorption of the product into one's skin.
- It is a humectant, which means that it helps attract moisture into the skin.
- It helps improve product application.
- It has mild preservative properties.
Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.
Glycerin 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.

On the technical side of things, xanthan gum is a polysaccharide - a combination consisting of multiple sugar molecules bonded together.
Xanthan gum is a pretty common and great ingredient. It is a natural, non-toxic, non-irritating ingredient that is also commonly used in food products.

Doesn't do much and it broke me out also I don't get the texture of this for a spot treatment
Initially I didn't like this but it was because the directions were not very clear to me. Even here on Skinsort it would line it up in the middle of the routine. Probably my fault in not using it right but now, I lather on a thick layer on any blemish or even on dark spots left from older acne before going to bed as the very last step. In the morning the blemishes are either gone or very much Show more

Normally I avoid products with alcohol, but it’s not an issue with this one. It’s well formulated so that it’s balanced out with other more hydrating ingredients. It absorbed nearly immediately and doesn’t dry out the skin. The results aren’t massive. But I just love the apothecary aesthetic and it works about as well as any other dark spot corrector.
Works as said
I have dark skin and lots of PIH. It lightens them. You can see quicker results with new PIH spots. Holygrail in my routine
