TI Studies on ozone therapy of acne vulgaris AU Gloor-M; Lipphardt-BA SO Z-Hautkr. 1976 Feb 1; 51(3): 97-101 ISSN 0301-0481 LA GERMAN CP GERMANY,-WEST PT JOURNAL-ARTICLE UI 76273387 Abstract Ozone therapy using the Vapozone 9, an instrument in normal commercial usage, has been carried out on the forehead of 16 male test persons on 7 consecutive days. Before the treatment began and at the end of the treatment period the skin surface lipids on the unchanged skin (casual level) and two hours after defatting the skin (replacement sum) were taken by direct extraction and analysed by means of thin layer chromatography. The results of these investigations rule out a decrease in the free fatty acids by this therapy. As a result of this finding it may assumed that no desinfecting effect on the corynebacterium acnes and other lipasereleasing microorganisms can be attributed to ozone therapy.
