Benzoyl peroxide is a tricky one for us here in the UK. Unlike other countries such as the US, it's much harder to get your hands on products containing the powerful ingredient, but that doesn't mean it's impossible. Currently benzoyl peroxide available as a face wash or treatment gel is can only be bought via prescription from your dermatologist or GP if you're experiencing frequent acne breakouts.
According to Dr. Roa, "It blocks bacterial growth, which is thought to cause whiteheads, blackheads, and pimples when it overgrows in a pore." While benzyol peroxide doesn't stop oil production, it can reduce oil on the skin temporarily.
