Acne commonly occurs during the age of teens especially during puberty, although it can also be seen in babies as well as adults. Acne could also be genetically inherited as if one's parents suffered severe acne problems, he or she might also suffer from it. Acne most visible external symptoms include pimples, blackheads, and whiteheads. They can be found mostly around the shoulder areas, chest, back and the neck, apart from just the face.

During puberty, teenagers undergo a number of hormonal changes such as estrogen and androgens hormones. These hormones stimulate the sebaceous glands to produce oils which then tends to block the skin pores. This is particularly noticeable in people with oily skins. A blocked skin pores will result in the skin bacteria being trapped underneath the skin. As such, when the body's white blood cells destroy the bacteria beneath the infected skin pore, a chain of chemical reaction would take place with the dead bacteria, fluids and other toxin matters, thus resulting in the skin forming pimples, whiteheads or blackheads. Often the skin becomes red, inflammed and may sometimes swells and itch too.

Benzoyl Peroxide is one of the most commonly used ingredient in mostly all over the counter acne solution products in the world today. Benzoyl Peroxide is an active ingredient that has been proven to successfully combat acne with fast and effective results. Normally a range of between 2.5% to 10% of Benzoyl Peroxide can be found in acne products.

As Benzoyl Peroxide may irritate the skins of people with known sensitive skins, symptoms such as skin redness, itchiness as well as making the skin peels may be resulted. Hence, a solution of about 5% or less Benzoyl Peroxide generally works well for people who are unable to tolerate high level of Benzoyl Peroxide.

Also, prolonged use of this Benzoyl Peroxide may damage the skins in the long term. Problems such as dry skins as well as premature skin aging may result. Symptoms like flabby skins and wringkles may form when this ingredient is used excessively. Nevertheless, Benzoyl Peroxide is still one of the best solution in fighting acne.
