The laser therapies or those containing light go beyond the top layer of skin. The laser therapy causes a damage to the glands making them less productive than before. The light treatments focus attention on the acne bacteria that is known to cause the infection and inflammation. When using these therapies for acne, the patient will see a difference in their skins appearance and feel. The scars they previously had on their skin will either be reduced significantly or taken away completely. This will depend on how deep they were to begin with. Three types of laser or light therapy is available today.
Filled with pus and shaped like a dome. Sometimes, they can become a cyst. However, if they don't they can heal on their own and will usually not leave any scar. Usually, it is easy to pop them when you are washing your face. Try to be careful during washing so that you can avoid popping them.
Retinoids Help Normalize KeratinizationAlthough the mechanism by which topical and systemic retinoids help restore acne follicles to a healthy state is unknown, it has been well demonstrated that they normalize keratinization within the infundibular region of the follicle, so that shed follicular cells slough to the surface of the skin rather than clump together and obstruct the pores.After exposure to retinoids, follicular cells actually turn over more rapidly than they would in a pre-acne state.Retinoic acid has a high affinity for the gamma retinoid receptors, which are believed to be integral to the pathogenesis of acne.In addition to their ability to reverse abnormal keratinization within the follicle, the topical retinoids - especially adapalene (Differin®), a naphthoic acid derivative - may have anti-inflammatory properties and thus may address two factors involved in the development of acne.
