Topic Breakdown
In this post, we're diving into a widely prescribed medication for acne treatment—benzoyl peroxide. You might recognize it by its brand names like Acnecide or PanOxyl. Benzoyl peroxide is an antiseptic that works to reduce the number of germs or bacteria on the skin's surface, making it a go-to solution for mild to moderate acne. Typically, it takes about four weeks to start showing results, and full effectiveness is usually seen between two to four months.
Benzoyl peroxide is available in various forms, including gels and face washes, often containing 5% of the active ingredient. Here in the UK, you can purchase these over-the-counter at pharmacies or shops. Some formulations also include potassium hydroxyquinoline sulfate, an antimicrobial agent that kills microorganisms on your skin. This combination is often sold under the name Quinoderm cream. Certain benzoyl peroxide products are available by prescription only, as they are mixed with other medications like antibiotics or retinoids. For instance, Duac Once Daily contains benzoyl peroxide and clindamycin (an antibiotic), while Epiduo Gel combines benzoyl peroxide with adapalene (a retinoid). For these formulations, a visit to a healthcare professional is necessary to get a prescription. Additionally, many popular skincare brands, such as Clean & Clear, Neutrogena, and Clearasil, offer benzoyl peroxide products, though typically at lower strengths.
Now, who can and can't use benzoyl peroxide? Most adults and children aged 12 and over can use it safely. However, it's not suitable for everyone. Avoid using it if you've had an allergic reaction to benzoyl peroxide, have damaged or broken skin in the treatment area, or suffer from severe acne with nodules or cysts. These severe conditions should be treated by a doctor to prevent scarring.
When it comes to dosage, benzoyl peroxide gel or face wash is usually applied once or twice daily. If you have sensitive skin, start with once a day before bedtime. Should your skin become dry or start peeling, reduce the frequency to once every two days until your skin adjusts.
Here’s a step-by-step guide on how to use the gel medication:
1. Wash your hands.
2. Clean the affected area with a mild skin cleanser and water.
3. Gently pat your skin dry.
4. Apply a thin layer of gel to the affected areas.
5. Wash your hands again.
A fingertip unit of gel—enough to cover the end of your finger—should treat an area twice the size of your palm. If you're treating your whole face, use a strip of gel about 2.5 centimeters long each time. Avoid strong sunlight when using benzoyl peroxide gel; an oil-free sunscreen or a moisturizer with SPF 30 can be helpful.
For the face wash, the process is similar:
1. Wash your hands.
2. Wet the area you want to treat.
3. Apply a small amount of the product to your hands.
4. Smooth it onto the affected area.
5. Leave it on for one to two minutes.
6. Rinse thoroughly with water.
7. Gently pat your skin dry and wash your hands again.
Two crucial points: keep benzoyl peroxide away from your eyes, and if it gets in, rinse thoroughly with lukewarm water. Also, it can bleach or discolor hair, clothes, towels, and bedding, so keep it away from these items.
How long should you use benzoyl peroxide? The duration depends on how quickly your acne improves. It usually starts working within four weeks, but you might want to continue using it to prevent acne from returning. If you forget to use it, don't worry—just start again as soon as you remember. Using too much can cause skin irritation; if this happens, wash off as much as possible and wait for the irritation to subside before resuming use.
Like all medications, benzoyl peroxide can cause side effects, though not everyone experiences them. Common side effects include dry skin, peeling, redness, and skin irritation. To manage these, apply an oil-free moisturizer, take shorter showers with warm water, and use the medication less frequently if needed. Serious side effects are rare but include swelling, blisters, and in very rare cases, anaphylaxis. If you experience severe symptoms, contact your doctor immediately.
If you're pregnant or breastfeeding, consult your doctor before using benzoyl peroxide. Generally, it's safe during pregnancy, but avoid formulations with retinoids. While breastfeeding, ensure the treated areas don't come into contact with your baby, and wash your hands before handling your child.
Finally, avoid using benzoyl peroxide with other drying or irritating skincare products, especially those containing alcohol. Always check product labels and consult your doctor if you're unsure.
