Choi Yoon Me Major in Skin care and Obesity Management Dept. of Cultural industry Graduate School of Cultural industry Sungshin Women's University

This study intends to make a comparative analysis of what facial acne care methods with Manual Lymph Drainage do make a change in the sebum(U zone, T zone), roughness, pore, pigment and sebum output of facial acne skin, and become a right indicator in taking care of acne skin as normal skin through subjective evaluation for skin-care effect that those surveyed feel. The subjects of this study were 18 persons with inflammatory and non-inflammatory acne such as comedo, papule, abscess, nodule and cyst in the face among nineteen-year-old to twenty-seven-year-old men and women living in Seoul and metropolitan areas. They were classified into experiment group(9 persons) performing general acne-care with Manual Lymph Drainage and control group(9 persons) performing only general acne-care without Manual Lymph Drainage. It carried out an experiment on both experiment group and control group total 10 times for 4 weeks - 3 times in the first week, 3 times in the second week, 3 times in the third week and 3 times in the fourth week. Besides, it conducted photography of the acne area and acne examination by experts for 30 minutes after Cleansing before experiment by 0 time, 5 times and 10 times to record the number of comedo, papule, abscess and nodule, measure the sebum, roughness, pore, pigment and sebum output of skin in half an hour, and go through the process of completing a questionnaire to inquire into the subjective evaluation for utilization effects. The result is as follows. First, the variation of skin condition before and after experiment of experiment group applying Manual Lymph Drainage showed that the sebum-U zone and the sebum-T zone significantly decrease by 32.5% and 42.5%, respectively(p<0.05). The roughness, pore and pigment have significantly decreased by 29.0%, 76.6% and 21.1%, respectively(p<0.01). The sebum output has decreased by 34.8%, but there was no statistically significant difference. The variation of skin condition before and after experiment of control group applying only general acne-care showed that the sebum-U zone and -T zone, and pore and pigment significantly decrease by 26.2% and 39.2%, and 59.0% and 21.0%, respectively(p<0.05),(p<0.01). The roughness and sebum output has decreased by 11.6% and 30.6%, respectively, but there was no statistically significant difference. As a result, experiment group has significantly decreased for the sebum(U zone, T zone), roughness, pore and pigment(p<0.05), and control group has significantly decreased for the sebum(U zone, T zone), pore and pigment(p<0.05). There was no statistically significant difference in the comparison between two groups, but all items of experiment group have more decreased than those of control group. Second, the change of acne states after experiment of experiment group and control group showed that for experiment group, the comedo and papule significantly decrease by 92.4% and 78.7%, respectively(p<0.05), (p<0.01). The abscess and nodule have decreased by 86.5% and 75.0%, respectively, but there was no statistically significant difference. For control group, the comedo, papule and abscess have significantly decreased by 89.7%, 65.9% and 78.9%, respectively(p<0.05), (p<0.01), (p<0.05). The nodule has decreased by 71.8%, but there was no statistically significant difference. In other words, there was a significant change of comedo and papule in experiment group(p<0.05), and there was a significant change of comedo, papule and abscess in control group(p<0.05). There was no statistically significant difference in the comparison of variation between two groups, but by item, experiment group has more decreased than control group. Third, the subjective evaluation for the effect of experiment showed that there is a statistically significant difference by group in the general subjective evaluation(p<0.01), and experiment group(M=4.13) has higher relative effect of experiment than control group(M=3.64). Besides, there was a statistically significant difference for pore states by sub-questions(p<0.05), and experiment group(M=4.33) had higher relative evaluation for pore states than control group(M=3.56). Above this, there was no statistically significant difference for 5 questions related to the improvement of roughness, pore states, sensitiveness, inflammation and the number of acne, but experiment group had higher marks than control group. As for all results stated above, there was no statistically significant difference, but the former was more effective for acne-care in all items than the latter, and chief of all, the roughness and pore in skin condition, and the comedo and papule in acne condition were more improved. Particularly, the former made more positive evaluation for pore than the latter in the subjective evaluation of those surveyed. Consequently, the result of this study will be useful in using as basic clinical data for application of Manual Lymph Drainage with a care method for improvement of acne skin.
