Ingredients Explained
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.
