Mastering Benzoyl Peroxide to Treat Acne Scars and Achieve Clearer Skin


Benzoyl peroxide does wonders to help with acne scars. It’s easily accessible in the form of gels, cleansers, and targeted spot treatments that don’t require a prescription. This versatile ingredient is available in various potencies, catering to those dealing with anything from mild to moderate breakouts.

Despite benzoyl peroxide’s remarkable ability to combat acne and its scars by eliminating pore-clogging dead skin cells and harmful bacteria, it’s not without its limitations. It’s essential to weigh the advantages and drawbacks and understand when consulting a dermatologist, a skincare specialist, becomes necessary if over-the-counter solutions fail to yield the desired results.

What Is Benzoyl Peroxide?

Benzoyl peroxide, a bactericidal agent, possesses the remarkable ability to combat acne by targeting the specific culprit, Propionibacterium acnes, a bacterium closely associated with acne development. This acne-causing bacterium meets its match in benzoyl peroxide, which is conveniently available in various over-the-counter formulations.

You can readily acquire benzoyl peroxide from specialized dermatological pharmacies in the form of gels, cleansers, or spot treatments. In addition, it can be found in higher concentrations in teeth whitening products and hair bleaching agents due to its inherent bleaching properties. Notably, it also proves effective in addressing dark spots, pimples, and acne scars.

What sets benzoyl peroxide apart from other topical antibiotics for acne, such as clindamycin, is its unique feature – it doesn’t allow our bodies to build up resistance to antibiotics. This means you can consistently use benzoyl peroxide as an acne treatment without the concern that its effectiveness will diminish over time.

The Types of Acne You Can Treat with Benzoyl Peroxide

The action of benzoyl peroxide in addressing and preventing acne revolves around its dual-purpose approach: eradicating subcutaneous bacteria while facilitating the exfoliation of dead skin cells and regulating excess sebum (oil) within the pores.


Benzoyl peroxide exhibits notable efficacy in managing inflammatory acne, a distinct form of acne distinguished by the presence of red, pus-filled blemishes, including pustules, papules, cysts, and nodules, in contrast to the more common whiteheads and blackheads.

Cystic Acne

Cystic acne stands out as the most severe and challenging form of acne to manage effectively. This relentless condition is marked by the presence of firm, subcutaneous nodules beneath the skin’s surface. These deep-seated pimples often lack the conspicuous “heads” that characterize other types of acne.

Cystic acne can be attributed, in part, to the presence of P. acnes bacteria, making it a stubborn foe. However, benzoyl peroxide, when used in conjunction with prescription medications, can be a valuable ally in the fight against cystic acne. If you find yourself grappling with this formidable form of acne, it’s advisable to seek the counsel of a dermatologist who can guide you toward the most suitable treatment options.

Blackheads and Whiteheads

Blackheads and whiteheads are indeed forms of acne, but they fall under the noninflammatory category because they lack the characteristic red, inflamed appearance commonly associated with other acne pimples.

If you’re contending with both blackheads and whiteheads, you might be curious about whether benzoyl peroxide is a suitable option for addressing these noninflammatory blemishes.

It’s worth noting that while benzoyl peroxide can be effective in targeting the excess oil and dead skin cells that contribute to clogged pores, it may not necessarily represent the optimal treatment choice for blackheads and whiteheads.

When it comes to addressing the red marks left in the wake of acne, commonly referred to as post-inflammatory erythema (PIE), benzoyl peroxide emerges as a highly effective option. However, using benzoyl peroxide for post-inflammatory hyperpigmentation (PIH) isn’t a great option, it’s advisable to turn to brightening agents like mandelic acid or hydroquinone for more suitable results.

How to Properly Use Benzoyl Peroxide

When embarking on a benzoyl peroxide regimen for acne treatment, it’s prudent to take a gradual approach. Initiate its use cautiously by applying the product only once every other day, allowing your skin to acclimate without triggering adverse reactions. Additionally, keep in mind that benzoyl peroxide can heighten your skin’s sensitivity to sunlight, so promptly apply sunscreen after each use.

If you’re incorporating a benzoyl peroxide gel into your skincare routine, follow these steps for optimal results: Start by cleansing your face with a mild and gentle cleanser, gently pat your skin dry, apply a thin layer of the benzoyl peroxide gel to the affected areas and leave benzoyl peroxide gel on, follow up with your moisturizer, and, finally, ensure you apply a sunscreen with an SPF rating of at least 30 as the last step in your skincare regimen.

How Long Should Benzoyl Peroxide be Left on Your Face

When utilizing a benzoyl peroxide face wash, create a lather and gently apply it to your face, allowing it to sit for approximately 5-10 minutes. Subsequently, rinse it off thoroughly with water. In the case of gel, cream, or lotion formulations, apply the product to your face for about 1-5 minutes before rinsing and gently patting your skin dry with a soft towel. As you progress, you may gradually extend the application time, leaving it on for a few hours to enhance the effectiveness of the treatment. Eventually, you can leave benzoyl peroxide on your face overnight.

Let Benzoyl Peroxide Help with Your Acne and Scars

Unlock the potential of benzoyl peroxide to help with your acne scars. Embrace its versatility and effectiveness, but do so with patience and care, gradually introducing it to your skincare routine. Whether you’re tackling inflammatory acne, cystic breakouts, or red marks from past acne, benzoyl peroxide offers promising results, but remember that for post-inflammatory hyperpigmentation, alternative brightening agents might be more suitable.

Consult with a dermatologist for personalized guidance. Safeguard your skin with sunscreen due to heightened sensitivity and adopt a methodical approach to application, allowing it to sit for varying durations based on your skin’s tolerance. With dedication and proper use, benzoyl peroxide can be a valuable ally in your quest for clearer, healthier skin.
