Acne
Skin care

In general, it is recommended that people with acne do not wash affected skin more than twice daily. The application of a fragrance-free moisturizer to sensitive and acne-prone skin may reduce irritation. Skin irritation from acne medications typically peaks at two weeks after onset of use and tends to improve with continued use. Dermatologists recommend using cosmetic products that specifically say non-comedogenic, oil-free, and will not clog pores.

Acne vulgaris patients, even those with oily skin, should moisturize in order to support the skin's moisture barrier since skin barrier dysfunction may contribute to acne. Moisturizers, especially ceramide -containing moisturizers, as an adjunct therapy are particularly helpful for the dry skin and irritation that commonly results from topical acne treatment. Studies show that ceramide-containing moisturizers are important for optimal skin care; they enhance acne therapy adherence and complement existing acne therapies. In a study where acne patients used 1.2% clindamycin phosphate / 2.5% benzoyl peroxide gel in the morning and applied a micronized 0.05% tretinoin gel in the evening the overwhelming majority of patients experienced no cutaneous adverse events throughout the study. It was concluded that using ceramide cleanser and ceramide moisturizing cream caused the favorable tolerability, did not interfere with the treatment efficacy, and improved adherence to the regimen. The importance of preserving the acidic mantle and its barrier functions is widely accepted in the scientific community. Thus, maintaining a pH in the range 4.5 - 5.5 is essential in order to keep the skin surface in its optimal, healthy conditions.
