Exogenous aging mainly refers to photo-aging, which is caused by environmental factors including ultraviolet exposure. Dextran is a homopolysaccharide composed of glucose as monosaccharide, and glucose units are connected by glycosidic bonds.
The purpose of this study was to explore the clinical efficacy of medical dextrose tincture liquid (medical dextrose tincture) in the treatment of facial photoaging.
Thirty-four volunteers were included in the randomized double-blind study. According to the random number table method, the subjects were randomized into control and treatment groups. The subjects in the control and treatment groups were treated with medical hyaluronic acid gel and medical dextrose tincture, respectively. They received mesotherapy therapy three times with an interval of 28 days between treatments. Video image acquisition was performed before treatment and 28 days after treatment. Skin moisture content, glossiness, heme content, collagen density, and elasticity were tested. The subjective evaluations of subjects and doctors before and after treatment were compared.
Compared with the pre-treatment baseline, medical dextran tincture significantly increased skin moisture retention, skin gloss, and skin collagen density (p<0.001). Additionally, the skin retraction time was significantly reduced, and the skin retraction time was also markedly decreased after treatment with medical dextran tincture (p<0.001). The effects of medical dextran tincture were more significant in comparison with medical hyaluronic acid gel (p<0.05). The subjective evaluation results of doctors showed that after 84 days of treatment, the overall skin photoaging score was significantly reduced (p<0.001). The subjective evaluation results of volunteers showed that the various skin problems of more than 50% of volunteers were improved after treatment.
Medical dextran tincture has obvious effects of moisturizing, increasing luster, improving skin redness, increasing skin collagen content and enhancing skin elasticity.
外源性衰老主要指光老化,它是由包括紫外线照射在内的环境因素引起的。右旋糖酐是一种以葡萄糖为单糖组成的同多糖,葡萄糖单元通过糖苷键相连。
本研究旨在探讨医用葡萄糖酊液(医用葡萄糖酊)治疗面部光老化的临床疗效。
34名志愿者纳入随机双盲研究。根据随机数字表法,将受试者随机分为对照组和治疗组。对照组和治疗组受试者分别接受医用透明质酸凝胶和医用葡萄糖酊治疗。他们接受了三次中胚层疗法治疗,每次治疗间隔28天。在治疗前和治疗后28天进行视频图像采集。检测皮肤水分含量、光泽度、血红素含量、胶原蛋白密度和弹性。比较治疗前后受试者和医生的主观评价。
与治疗前基线相比,医用右旋糖酐酊显著提高了皮肤水分保留率、皮肤光泽度和皮肤胶原蛋白密度(p<0.001)。此外,皮肤回缩时间显著缩短,医用右旋糖酐酊治疗后皮肤回缩时间也明显缩短(p<0.001)。与医用透明质酸凝胶相比,医用右旋糖酐酊的效果更显著(p<0.05)。医生的主观评价结果显示,治疗84天后,整体皮肤光老化评分显著降低(p<0.001)。志愿者的主观评价结果显示,超过50%的志愿者在治疗后各种皮肤问题得到改善。
医用葡萄糖酊具有明显的保湿、增加光泽、改善皮肤发红、增加皮肤胶原蛋白含量和增强皮肤弹性的作用。
