Acne is a skin disease often commonly characterized by the outburst of pimples on the skin caused due to pore blocking.

It is common to both gender is often a result of hormonal surges and is as such common in the adolescence phase, i.e., during and after puberty.

The onset of acne is early and more common in females. In a study, 231 women and 130 men were seen to have a degree of facial acne.

While the overall prevalence in women was 54%, in men it was only 40%.

Acne, being a widespread problem, has a lot of clinically approved treatments which include antibiotics, oral medications, and others.

The use of Benzoyl Peroxide is an effective and common solution to the problem of acne.

About Benzoyl Peroxide

Benzoyl Peroxide is an organic compound that works as a powerful anti-microbial agent destroying both bacteria and yeasts.

It belongs to the peroxide family.

Benzoyl Peroxide has emerged as one of the most common ingredients for the treatment of acne usually used in the form of some gel, cream, facemask or a cleansing bar and is used to treat mild or moderate acne.

Apart from being a treatment to acne, its other major application includes its antiseptic and bleaching properties and it has been included in the list of essential medication needed for basic health system by the World Health Organization

Benzoyl Peroxide for Acne

Benzoyl Peroxide works in two ways to treat acne. First, it functions as an anti-microbial agent.

It is the only known substance that can bring oxygen under the skin and since bacteria cannot survive in oxygen, it eradicates 99.9% of the acne-causing bacteria when used in adequate dosage.

Secondly, it functions as a drying and peeling agent, clearing the pores of the oil and causes the skin to dry and turnover and prevents the outbreak of bacteria.

It also reduces inflammation.

Application of Benzoyl Peroxide for Acne

It is typically applied in the form of a gel or cream, only to the affected area, in the concentration ranging from 2.5% to 10%, depending on the frequency and severity of the acne.

It may be used in combination with other acne treatments, for example, in combination with a topical retinoid.

Two common combination drugs include Benzoyl Peroxide/clindamycin and adapalene/ Benzoyl Peroxide.

Dosage

In non-prescription form, this drug is available in the US for concentrations ranging from 2.5% to 5% up to 10 %, and for any higher concentration, a doctor’s prescription is a must.

It is usually advised that treatment should begin with a low concentration of 2.5% Benzoyl Peroxide.

Research suggests that while 2.5% concentration is better tolerated than 5% or 10%, the more effective concentrations range from 5% to 10% and a majority of treatments use a higher concentration.

It must be used in adequate dosage with a properly applied peroxide regimen.

It is suggested to apply the lowest concentration and then with time as the skin develops its tolerance for the drug, increase the concentration to a higher level causing better and subsequent clearance of acne.

Storage

This medication should be kept tightly closed in a cold and dry place away from moisture.

The National Institute of Health, USA suggests that the means of proper disposal should be consulted with the pharmacist.

Possible Side effects of benzoyl peroxide

Allergy: It might cause an allergic reaction with symptoms of rashes, irritation, and swelling, especially of the face, tongue, and throat, severe dizziness and trouble breathing.

In case of severe allergy, Benzoyl Peroxide should be discontinued in consultation with the doctor and another treatment should be sought for acne.

According to a study, around 1 % to 3% of the people are severely allergic to Benzoyl Peroxide.

Skin reaction: It may include dryness, itching, peeling of skin along with reddening and irritation, especially in the beginning of the treatment.

To reduce dryness the concentration of the medication must be reduced to the lower levels (2.5%) if the higher concentration is being used.

In order to avoid irritation, the frequency of use should be reduced and if irritation still persists, its use must be stopped altogether.

Discontinuing for some time and starting again might help because it gives time for the development of tolerance of the drug to the skin.
