Benzoyl Peroxide – Effective Treatment for Mild Acne Symptoms

Benzoyl peroxide is a widely used and highly effective first-line treatment for mild acne, characterised by whiteheads, blackheads, and occasional inflamed pimples.

Available as a gel or face wash, benzoyl peroxide is often sold under the brand name Acnecide in pharmacies.

For moderate to severe acne (featuring papules, pustules, or cysts), stronger prescription treatments may be recommended.

How Does Benzoyl Peroxide Work?

Acne is commonly caused by Propionibacterium acnes, a bacteria that thrives in the oil (sebum) produced by your skin.

Benzoyl peroxide combats this by:

  1. Killing acne-causing bacteria: Reduces bacterial growth and prevents infection.
  2. Reducing inflammation: Minimises redness and swelling.

This treatment works effectively on acne affecting the face, chest, and back.
