Acne and pimples are among the most common skin concerns worldwide, affecting both teenagers and adults. One of the most effective over-the-counter treatments widely recommended by dermatologists is benzoyl peroxide gel. Known for its antibacterial and anti-inflammatory properties, it works wonders in reducing acne breakouts, treating pimples, and even improving the appearance of acne scars over time.
What is Benzoyl Peroxide Gel?
Benzoyl peroxide gel is a topical medication commonly used in the treatment of acne vulgaris, blackheads, and pimples. Available in different strengths (2.5%, 5%, and 10%), it is often prescribed by dermatologists depending on the severity of acne.
This gel works in three primary ways:
- Kills acne-causing bacteria (Propionibacterium acnes)
- Exfoliates dead skin cells, preventing pore clogging
- Reduces oiliness, which minimises new breakouts
How Benzoyl Peroxide Gel Works for Pimples
1. Kills Bacteria
Acne is largely triggered by bacteria that thrive inside blocked pores. Benzoyl peroxide releases oxygen when applied to the skin, killing the bacteria that cause pimples.
2. Reduces Pimples and Inflammation
It decreases swelling, redness, and prevents new pimples from forming by clearing existing blockages in pores.
3. Prevents Blackheads and Whiteheads
Regular use of benzoyl peroxide prevents pore congestion, which reduces the appearance of comedones (blackheads and whiteheads).
How Benzoyl Peroxide Gel Helps with Acne Scars
While benzoyl peroxide is not specifically a scar-removal agent, it indirectly helps by:
- Preventing new breakouts, allowing old scars to heal
- Reducing redness around scars, making them appear less noticeable
- Improving overall skin texture and lightening post-inflammatory marks when combined with treatments like adapalene gel or salicylic acid face wash
How to Use Benzoyl Peroxide Gel
- Cleanse: Wash your face with a mild cleanser or a salicylic acid face wash.
- Apply a thin layer: Use a pea-sized amount of benzoyl peroxide gel on the affected areas.
- Start slow: Begin with once every two days to see how your skin reacts.
- Increase frequency: If no irritation occurs, you can apply once or twice daily.
- Moisturise: Always use an oil-free moisturiser to avoid dryness.
- Use sunscreen: Benzoyl peroxide can make your skin more sensitive to the sun.
