약초필링 후 함량이 다른 세라마이드적용 피부관리가 홍반과 보습에 미치는 영향

Abstract

Everyliving thing goesthrough the aging process. Cells age starting from birth until we reach death. Human aging usually pertains to the deterioration of the body, primarily evident in the skin. Body functions deteriorate as well as the skin's vitality. In order to improve the facial skin, which is exposed to the harsh external environment, people resort to certain remedies, such as peeling. Peeling is known to alleviate hyperpigmentation due to exfoliation, acne mitigation and maintenance of clear skin. In the stratum spinosum of the epidermis, keratinocyte,thecollagen of dermis cause an indirect rejuvenated effect because of the proliferation of collagen production from fibroblast. But unfortunately, despite its positive effects, peeling is still accompanied by side effects such as erythema, dehydration, and skin irritation. This happens due to the deterioration of the skin barrier resulting to dehydration. Accordingly, we intend to check whether skin care applying ceramide after peeling replaced damaged skin barrier and minimized such side effect to improve skin. Ceramide is one of the most important ingredients that keeps the skin barrier's function of protecting the skin from irritation due to external stimulation. It was discovered that without ceramide, the skin's moisture easily evaporates, which makes it very dry, resulting to worsening of skin troubles. Also, the quantity of ceramide present is directly proportional to the effectiveness of the skin barrier's function, which is to prevent the moisture within the horny layers from evaporating. This study aims to prove that applying ceramide to the skin not only functions for skin repair and maintenance, but also help restore the damaged skin barrier. However, we could hardly find any other report regarding the use of ceramide in skincare. Therefore, this study will be used as basic reference to the application of various amounts of ceramide on erythematous and dehydrated skin for healing and moisturizing after herbal peeling. In this study, experiment was conducted for three groups (NC :No Contents of Ceramide Group, LC: Low Contents of Ceramide Group, HC : High Contents of Ceramide Group) of women in middle age whose peeling care experience is more than six months and skin type is no sensitive skin confirmation through facial diagnosed conducted by experts. The test was rendered a total eight times, between May 1 to July 19, 2012 and skincare was given in one-week interval. After the 1st and 8th experiment, skin erythema index, moisture contents ,TEWLandroughnessweremeasuredandchangesin skincondition through the experiment wereanalyzed.Fromtheresultsofanalyzingdetailsdataand questionnairesurveyonsubjectivesatisfaction,conclusionsweredrawn as follows. The first, if examining the changes of erythema, HC group decreased from 279.25 before the experiment to 242.17 after it (p<0.01), LC group decreased from 271.53 before it to 253.78 after it (p<0.001), NC group decreased from 283.13 before it to 271.99 after it (p<0.001). The second, with regard to moisture of the HC group, LC group and NC group after the experiment, HC group increased from 33.28 before the experiment to 42.93 after it (p<0.001), LC group increased from 32.36 before it to 38.80 after it (p<0.001), NC group increased from 33.06 before it to 38.34 after it (p<0.01). The third, in case of TEWL, HC group decreased from 12.80 before the experiment to 7.23 after it (p<0.001), LC group decreased from 10.03 before it to 5.84 after it (p<0.001), NC group decreased from 13.28 before it to 12.89 after it (p<0.001). The fourth, if examining the changes of roughness, HC group decreased from 20.75 before the experiment to 13.07 after it (p<0.001), LC group decreased from 18.62 before it to 11.08 after it (p<0.001), NC group decreased from 17.20 before it to 12.21 after it (p<0.001). The fifth, where a survey was conducted and satisfactory results were achieved after the experiment. HC group and LC group were subjectedtoapplicationofemulsionwithceramideasskincare, resulting increased moisture and decreased erythema, roughness and symptoms as compared to NC group where there was application of non-ceramide containing emulsion for skincare. Overall, the subjects responded that applying emulsion containing ceramide as skincare after peeling was helpful to improve the skin condition. Based on the above results, the higher contents of ceramide, the more showed positive effects on improving and relieving erythema, dehydration, skin irritation. This researcher expects that studies on notonlythequantityofceramidesbutalsothecompositionof ceramides emulsion of the future can be progressed more variously and widely so that applying emulsion containing of ceramide can be popularized as skincare after peeling.
