The purpose of this study was to compare the improvement of acne skin according to the difference in AHA concentration ratio of body peeling mist containing Hydroxy Acids in 30 healthy people with acne in the body. We observed back acne and skin conditions for 6 weeks with three comparison groups containing 21.65% AHA, 24.00% AHA, and 26.50% AHA. As a result of observing acne skin improvement after 6 weeks, the difference between the three groups was not statistically significant, but the change in the ratio to the baseline of inflammatory and non-inflammatory acne lesions and the change in Michaelson’s Acne Severity Index (ASI) were significantly reduced according to the measurement time of each group. As a result of observing skin improvement in Sebum, Flakiness, Moisture after 6 weeks, the L group showed statistically related changes in skin moisture, the M group showed skin sebum, skin flakiness, skin moisture, and the H group showed statistically related changes in skin flakiness, skin moisture. In addition, the subjective skin irritation was the highest in the H group, and the subjective feeling of usage was the highest in the M group. Collectively, the results indicated that acne skin improvement rate and subjective satisfaction were the highest in group M using HA’s 32.00% product (AHA 24.00%), which is useful for the production and development of acne care cosmetics.
