What is benzoyl peroxide?

Benzoyl peroxide is a common ingredient in skin care products, mainly those designed to treat acne. It looks like a white powder, and is soluble in many liquids, but not in water. The main role of benzoyl peroxide is to kill bacteria on the skin, especially those that can cause acne. 

Alongside this, it also helps to reduce swelling on the skin and cleanse clogged pores by removing dead skin cells. Benzoyl peroxide can be found in various forms such as creams, gels and cleansers. It is usually applied directly to the skin affected by acne. It is a popular and effective treatment for acne vulgaris.

What effects did Benzacne ointment produce? The benzoyl peroxide contained in it destroyed the bacteria responsible for acne lesions, namely the anaerobic Propionibacterium acnes, as well as the cutaneous staphylococcus epidermidis. In addition, it reduced sebum production and facilitated the exfoliation of dead skin.

How to use benzoyl peroxide?

Since you already know what benzoyl peroxide is and how it works, let's move on to the most important aspect: how to apply it to the skin. Follow these tips - it will help you achieve the best results while minimising potential side effects.

Choose the right product

Choose a product designed for your skin type and the problems you face. Benzoyl peroxide comes in a variety of forms, such as face washes, gels, creams or spot treatments. Each type serves a unique purpose.

Facial cleansers

If you have oily or acne-prone skin, a facial wash with benzoyl peroxide can be a great option. These products help to remove excess sebum. They can be used once or twice a day.

Gels and creams

These are products to be left on the skin for longer. They allow prolonged contact of benzoyl peroxide with the skin. They are suitable for treating larger areas of acne and can be applied once a day.

Point treatments

Point treatments are best for single pimples or small clusters of pimples. They usually have higher concentrations of benzoyl peroxide and should be used sparingly.

Start with a lower concentration

Benzoyl peroxide products come in different concentrations, usually from 2.5% to 10%. To get the best results and minimise possible irritation, it is recommended to start with the lowest concentration. If your skin tolerates them well, you can gradually increase the concentration as needed. 

Apply basic hygiene and safety rules

To effectively incorporate benzoyl peroxide into your routine skin care, follow these tips:

Clean your face

Before applying benzoyl peroxide, make sure your skin is clean and dry. Use a gentle water-based cleanser without fragrance or dyes.

Apply a thin layer

Use a thin layer of your chosen benzoyl peroxide product on acne affected areas. Excessive application can lead to excessive dryness and irritation.

Be consistent

Consistency is the key to visible results. Use the product as recommended on the pack, usually once a day, for best results.

Before use, do a patch test

As with any new skincare product, do a patch test to check for possible reactions. Apply a small amount of benzoyl peroxide to the inner arm and wait 24 hours. If no irritation occurs, you can most likely use the product safely.

Keep your skin moisturised

The use of benzoyl peroxide can cause dry skin. Ensure that your skin is properly hydrated by using a non-comedogenic moisturiser.
