There is no single best mode for management of all acne lesions . Control of different forms is determined by many factors, including types of lesions present, duration of disease, past and present response to modalities, tendency for scarring and development of spots. Knowing the symptoms and early treatment are the key to a successful management. Cystic acne may be hormonally mediated from within and without the skin, which involves in dynamic generation of androgens and imparts a conceding aspect to cystic acne treatment. Current medical condition, comorbidities, and medications especially oral contraceptives, corticosteroids and topical antibiotics may affect treatment of cystic acne. Psychological factors may have great impact on removal of lesions and may explain chronicity of stress related acne. Also adult patient’s overall hygiene, facial care, hair grooming and use of cosmetics must be considered. There are three important points that patients should be aware of. First, six to eight weeks of therapy may be required before improvement is noted. Second, body lesions including back, chest, shoulder lesions respond more slowly to a topical modality than do those on the face. Third, mechanical manipulation of lesions can affect course of the disease and contribute to formation of scars.
A rational approach to topically treat acne using an skin care regimen which requires multiple steps for cleansing and maintenance and prevention could be to selectively target the management to factors involved in its development and pathogenesis. These approaches provide a guideline to prevent and topically treat acne based on severity. First, prevention of comedones (whiteheads and blackheads). Second, sebum production reduction and control of skin surface lipids and a oily face. Third, preventing rupture of comedones. Fourth, resolution of inflammation concurrent with its control. Fifth, preventing and correcting acne scars. Treating these sequels could become even more cumbersome.
It is important to note that severe form as in cystic form may warrant combination therapy and must be consulted with a physician. Best approach for mild forms such as comedones (whiteheads and blackheads), small pustules and scattered papules are various treatment modalities with desquamating agents such as benzoyl peroxide. Among leading over-the-counter treatments benzoyl peroxide could be counted. Its antibacterial efficacy is noteworthy in rapid destruction of Porpionibacterium acnes. This suppressive effect is much faster compare with that of antibiotics. In contrast to antibiotics, resident organisms do not become resistant to this agent. This agent also demonstrates anti-inflammatory effect due to a reduction of oxygen free radicals. Its comedolytic effect is comparatively slight in contrast to other topical agents used to treat acne. Contact allergy is quite rare with it.
A comedolytic over-the-counter such as salicylic acid (a beta hydroxy acid), which could be used as alternative or adjunct to benzoyl peroxide. This combination therapy for acne maybe among modalities for moderate forms and may be equally used for cystic acne treatment. Salicylic acid comedolytic activity justifies its therapeutic value. Keratolytic activity of this BHA causes peeling and removal of top layer of the skin. This can result in preventing the follicles from getting plugged. Salicylic acid is also moderately effective in destructing Porpionibacterium and shows moderate antibacterial efficacy. Combination therapy of salicylic acid with benzoyl peorxide have been postulated by a more recent study. Application of AHA’s (alpha hydroxy acids) such as glycolic acid may resolve the comedones and prevent more severe form. Use of alpha hydroxy acids alone is not indicated. However, a positive effect through control of sebum production and ductal hypercornification is likely.
Tretinoin in its oral form, isotretinoin is used in refractory cases for cystic acne treatment. Topical forms is used for managing acne in its mild to moderate forms. Treatment of acne vulgaris during pregnancy warrants certain considerations and more specific treatment protocol. Guidelines of care aids us to treat according to more conventional methods yet more evidence based medicine. Herbs and naturally-derived preparations may become more studied and recognized in future acne armamentarium. Lately, diet has gained far greater acknowledgement and commensurate dietary precautions have been introduced in management of acne vulgaris.
