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.
Working internally, systemic treatments may be taken orally, as in a pill or injected into the skin. Systemic treatments are used in the case of moderate acne, when topical treatments aren't enough, as well as for severe and cystic acne. Systemic treatments are available by prescription only and are often used in conjunction with topical treatments. Systemic acne treatments include oral antibiotics, hormonal treatments, and isotretinoin (sold in brand names such as Accutane).
