One of the problems with benzoyl peroxide topical acne treatments is that they can be quite irritating, particularly to sensitive skin. Those fans of benzoyl peroxide will thus be pleased to learn that one skin care company that supplies prescription acne and skin care products is releasing a treatment with a delivery system that reduces benzoyl peroxide's irritating effect. Called NeoBenz Micro, this acne treatment will be available only by prescription, which is one drawback. On the plus side, it should mean that the acne sufferer is given the appropriate strength to their particular needs. It is aimed at helping people with mild to moderate acne, and comes in three strengths. These are 3.5% benzoyl peroxide, 5.5% benzoyl peroxide, and 8.5% benzoyl peroxide. The difference in this treatment as compared to regular benzoyl peroxide solutions, is that it is a time release product. The method designed by SkinMedica, NeoBenz Micro's developer, uses very small 'sponges', called microsponges. These hold the active ingredient, in this case benzoyl peroxide, to be slowly released throughout the day. It means that though acne is kept in contact with benzoyl peroxide for the whole day, only small amounts of it are released onto the skin. These amounts are enough to be effective but far less irritating. The side effects that this benzoyl peroxide acne treatment aims at reducing are rashes, skin soreness, and irritation. Aside from the unpleasant feeling these effects create, they unfortunately also reduce the effectiveness of benzoyl peroxide in clearing acne. NeoBenz Micro is one example of a new trend in the pharmaceutical industry. It aims at taking existing products and developing new ways to package and deliver the active ingredients, thus effectively modernizing many treatments. The emphasis in the past had been more research oriented - finding new and more powerful treatments rather than fine tuning existing ones that were proven to work. Other examples of this phenomena include converting treatments into sprays, with the effect of increasing absorption and convenience. MedPharm, a research contracting firm, is turning one eczema treatment and two acne treatments into sprays. These are still in the development stage, however.
