The Pathogenesis of Acne
Acne, the major disorder of the pilosebaceous unit, presents as noninflammatory (closed and open comedones)
and inflammatory (papules, pustules, nodules) lesions. Several factors contribute to the pathogenesis of acne
including androgens (testosterone and DHEA-S), increased sebum production, P. acnes-driven inflammation,
and abnormal follicular epithelial differentiation.
Treatment for acne focuses on the resolution of inflammation, downregulation of sebum production,
and elimination of the noninflammatory lesions manifested as micro-comedo and comedones.
In rosacea, therapy is typically anti-inflammatory in nature. For acne, the choice of therapy usually
depends on the grade and severity. Rosacea therapy is determined by the stage.
Retin-A Micro is indicated for the topical treatment of acne vulgaris. The new medication,
cleared for marketing by the U.S. Food and Drug Administration (FDA) on February 7,
1997, uses Advanced Polymer System's technologically advanced Microsponge system to deliver the
maximum strength of the Retinoin with minimal irritation. The product is marketed by Ortho Dermatological.
