Is benzoyl peroxide effective for acne treatment

The acne problem bothers many people, so of course we should pay attention to understanding the correct and effective treatment methods. Acne removal work cannot be ignored. Benzoyl peroxide has a certain effect on acne removal because it can eliminate some acne, pustule bacterial infections, and has a certain therapeutic effect on non-inflammatory skin damage and acne, so if you want to remove acne, you can also try this method.

1. The principle of benzoyl peroxide in treating acne:

One of the causes of acne is that Propionibacterium acnes breaks down sebum to release fatty acids, which stimulate hair follicles and cause inflammation, resulting in different skin lesions. Benzoyl peroxide can inhibit the reproduction of Propionibacterium acnes and the formation of free fatty acids.

Topical benzoyl peroxide can penetrate into the sebum follicles, slowly release oxygen, and be broken down by cysteine ​​into benzoic acid and free oxygen. Each gram of benzoyl peroxide releases 4 ml of oxygen in 24 hours, oxidizing the Propionibacterium and its bacterial protein in the skin and hair follicles, thereby killing bacteria. This in turn reduces the free fatty acids produced by bacterial lipase.

Second, the side effects of topical benzoyl peroxide:

Irritating skin inflammation. Experimental statistics show that 3% of people develop irritant dermatitis after using benzoyl peroxide, and the incidence is positively correlated with drug concentration, number of times used and duration of treatment.

Symptoms include stinging, itching, tightness and burning sensations, erythema, edema, dryness and scaling.

To reduce the occurrence of irritant dermatitis, some people recommend using benzoyl peroxide to treat acne at night, washing it off in the morning, and using retinoic acid preparations during the day. In addition, the use of benzoyl peroxide can also cause allergic contact dermatitis, which is more common in patients with leg ulcers.

3. Precautions for topical use of benzoyl peroxide:

1. Avoid contact with colored substances (such as clothes, hair, etc.) to avoid discoloration;

2. Avoid contact with eyes, lips and other mucous membranes. If contact occurs, rinse immediately with clean water.

3. If a large amount of desquamation, erythema or edema occurs, the drug should be discontinued immediately;
