Cellulose masks obtained from natural sources such as bacteria are of interest as cosmetic devices for the treatment of dry skin because they not only improve hydration of the skin, but have low toxicity and are biodegradable. The aims of this study were to determine the in vivo effects of a cellulose mask obtained from Acetobacter xylinum on skin characteristics and to evaluate user satisfaction with the product.
Thirty healthy Thai volunteers aged 21-40 years participated in the study. The volunteers were randomly separated into a control group and an experimental group. For the control group, volunteers were assigned to apply moist towels to the face for 25 minutes. For the experimental group, the volunteers were assigned to apply the masks, ie, translucent patches which could be fitted onto the face for the same period. The following week, the groups were changed over to the alternative treatment. Skin moisture, sebum, elasticity, texture, dullness, and desquamation levels were assessed using a system used for routine skin counseling before applying the trial product and five minutes after its removal. Degree of satisfaction with use of the cellulose mask was investigated using a five-point rating scale.
The cellulose mask increased moisture levels in the skin significantly more than moist towels (P < 0.05) after a single application. No obvious effects on other skin characteristics were found. The cellulose mask product rated around 4/5 on the satisfaction rating scale.
A single application of the trial cellulose mask enhanced moisture uptake by facial skin. Users also reported being satisfied with the trial product.
从细菌等天然来源获得的纤维素面膜作为治疗干性皮肤的美容器械备受关注，因为它们不仅能改善皮肤的水合作用，而且毒性低且可生物降解。本研究的目的是确定从木醋杆菌获得的纤维素面膜对皮肤特性的体内影响，并评估用户对该产品的满意度。
30名年龄在21 - 40岁的健康泰国志愿者参与了该研究。志愿者被随机分为对照组和实验组。对于对照组，志愿者被分配用湿毛巾敷脸25分钟。对于实验组，志愿者被分配使用面膜，即可以贴合面部的半透明贴片，敷脸时间相同。接下来的一周，两组交换进行另一种治疗。在使用试验产品前和去除产品五分钟后，使用用于常规皮肤咨询的系统评估皮肤水分、皮脂、弹性、质地、暗沉和脱屑水平。使用五点量表调查对纤维素面膜使用的满意度。
单次使用后，纤维素面膜使皮肤水分水平的增加显著高于湿毛巾（P < 0.05）。未发现对其他皮肤特性有明显影响。纤维素面膜产品在满意度量表上的评分约为4/5。
单次使用试验性纤维素面膜可增强面部皮肤的水分吸收。用户也报告对试验产品感到满意。
