Benzoyl Peroxide is famous for fighting acne. This is because it does a variety of tasks on the skin: it helps reduce excess oil, kill bacteria, and clear out dead skin cells. In other words, it is effective at unclogging pores.

These properties make it great at fighting different types of acne, including cystic and inflammatory types of acne.

When targeting the bacteria in your pores, Benzoyl Peroxide has been shown to kill the bacteria without causing sensitivity. It also helps keep your skin's natural bacteria and biome balanced. Having a healthy biome protects your skin from external harmful factors.

Once Benzoyl Peroxide is absorbed into the skin, our bodies turn it into benzoic acid and quickly exits in urine.

When using Benzoyl Peroxide, it may be irritating for some people due to a variety of reasons, such as a broken skin barrier or just an allergic reaction. We recommend speaking with a professional about using this ingredient if you have concerns.

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.

Great spot treatment but expensive
I used it as a spot treatment and it worked beautifully for me. I have sensitive combo skin and every time I’ve got some whitehead i used it on it and in it disappeared. Definitely wouldn’t use it...

I used it as a spot treatment and it worked beautifully for me. I have sensitive combo skin and every time I’ve got some whitehead i used it on it and in it disappeared. Definitely wouldn’t use it every day or as a moisturiser. The only reason why i don't like it is, because it's really expensive.
