| Abstract: | Common cosmetic dermatitis is composed of mainly chronic irritant contact dermatitis, allergic contact dermatitis and pigmented cosmetic dermatitis. Special types include atopic contact dermatitis due to cosmetics, complication of corticosteroid dermatosis, and eyelid dermatitis. Common cosmetic sensitizers are various fragrances, pigments and base components. The best treatment to stop the recrudescence of cosmetic dermatitis is to perform patch testing to discover causative allergens for the patients, so that allergen control becomes possible later. It has been the only effective method to perfectly cure the disastrous pigmented cosmetic dermatitis with Mongoloids in the past. The avoidance of very allergenic fragrances (class A fragrances in the table) and two pigments, D&C Red No.31 and Yellow No.11 is essential to reduce cosmetic dermatitis of the consumers. The introduction of guidelines to avoid strong sensitizers is recommended. Recently, eyelid dermatitis due to allergy or irritation has been common and rubbing itchy eyelids has led to blindness due to retinal abrasion. Adding various plant components seemed to have increased the irritation, and it is better to be avoided hereafter. |
