Rosacea is a chronic inflammatory dermatosis for which “trigger” avoidance and proper skin care are essential, along with drug therapy. To avoid irritation, cosmetic products used in daily skin care should be of good quality and hypo-irritation. In Japan, azelaic acid formulations which are used to treat rosacea and acne vulgaris, are available as quasi-drugs also called medicated cosmetics. Cosmetics that correct and camouflage redness may be useful in improving the quality of life of rosacea patients. Rosacea-like dermatitis is a medical condition similar to rosacea caused by topical steroids or other medical agents. Although the causative drugs should be discontinued, rosacea-like dermatitis is thought to be an exacerbation of rosacea caused by those drugs, and treatment and skin care similar to that for rosacea may be useful. Seborrheic dermatitis is a chronic recurrent dermatitis caused by the involvement of Malassezia, an indigenous yeast fungus of the skin. Skin care with cleansing agents containing ingredients that prevent Malassezia growth may be useful in treating seborrheic dermatitis along with drug therapy.
