Investigations on the development and regression of corticosteroid-induced thinning of the skin in various parts of the human body during and after topical application of amcinonide

In 15 subjects 6 different parts of the body were treated with the potent topical corticosteroid (CS) amcinonide once a day for 21 days. The skin thickness of the treated areas was measured sonographically at intervals of 2 days. After completion of the CS application the regression of the CS-induced reduction in skin thickness was measured for a further 14 days. A clear thinning of the skin could be measured after only 4 days and continued up to the 21st day of treatment. This thinning regressed completely in all areas after 10-12 days. The thinning and regression curves were very similar for all body areas. Differences in intensity of thinning were evident. No tachyphylaxis was detected.
