An Experimental Study on Comedogenic effect of Various Korean Cosmetocs / 대한피부과학회지

ABSTRACT

Varioua articles have been reported that extemal contactants were the cause Acne venenata. The daily use of cosmetics are tbe cause of Acne minor in adult wamen. To distinguish this from other type of Acne venenata due to extemal contactants Kligman had coined the term Acne cosmetica, which is a low grade persistant acneiform eruption with occasional papulopustulea in adult women. The authors have tested a wide range of available cosmetics(Total twenty including four kinds of cold cream species, two of cleansing cream species, three of nutrient cream species, six of lotion species, three of foundation make up species and two of foreign cosmetics) using the rabbit ear assay recently popularized by Kligman in order to evaluate comedogenic effects of various Korean ccsmetics. The results a.re as follows. 1. Among these twenty facial cosmetics, We observed no comedogenccicy in two facial cosmetics, mildly comcdogenecity in twelve facial cosmetics, moderately comedo- genecity in four facial cosmetics and severe comedogenecity in two facial cosmetics. 2. Histologic gradings were paralleled the findings of tbe naked eye in up to 65% 3. There were significant differences on comedogenecity between Korean cosmetics and foreign cosmetics which used by Kligman. 4. There were no significant diffrences between cold cream species, cleansing cream species. nutrient, cream species, lotion species and foundation make up species. 5, There were various differences among twenty kinds of every cosmetic specie.
