This was an open-label, single-center clinical study to evaluate a topical association of SCA ( secretion) with regenerative and antioxidant ingredients, according to the type and area of the face, on the improvement of signs of skin aging.
One hundred and twenty female participants aged between 40 and 65 years, with facial aging complaints (presence of static, dynamics wrinkles, loss of elasticity, and skin firmness) were randomized into two groups according to the type of skin: normal-oily and normal-dry, and 40 participants were randomized for evaluation of the periocular area (with the presence of wrinkles, expression lines, and dark circles) with both types of skin. The groups received serum for normal-oily skin, a cream for normal-dry skin, and a cream for periocular and eyelid skin (eye area). All the participants were evaluated by a dermatologist and submitted to hydration evaluation by corneometry, elasticity and firmness measures complementarily, and images were collected in confocal reflectance microscopy.
Topical skin treatment with the association of SCA with antioxidant ingredients (green coffee oil, olive oil, ectoine, hyaluronic acid, and peptides) was able to promote significant clinical and subjective improvement of all signs of skin aging. This improvement was presented at the epidermal level, with improved hydration levels measured by corneometry and epidermal thickness, and at the dermal level, with improvement of the firmness and elasticity parameters, measured by cutometry, from 45 days of use.
All the evaluated topical formulations seemed to be an effective alternative for the progressive treatment of signs of skin aging, since they demonstrate a real improvement of dermal-epidermal structure and function with high safety margin for long-term use.
这是一项开放标签、单中心临床研究,旨在根据面部类型和区域,评估分泌型SCA与再生及抗氧化成分的局部联合应用对改善皮肤衰老迹象的效果。
120名年龄在40至65岁之间、有面部衰老问题(存在静态纹、动态纹、弹性丧失和皮肤松弛)的女性参与者,根据皮肤类型随机分为两组:中性油性和中性干性,40名参与者被随机分配用于评估两种皮肤类型的眼周区域(有皱纹、表情纹和黑眼圈)。这些组分别接受针对中性油性皮肤的血清、针对中性干性皮肤的乳膏以及针对眼周和眼睑皮肤(眼部区域)的乳膏。所有参与者均由皮肤科医生进行评估,并通过角质层水合测量、弹性和紧致度测量进行补充性水合评估,同时在共聚焦反射显微镜下采集图像。
SCA与抗氧化成分(绿咖啡油、橄榄油、依克多因、透明质酸和肽)联合进行局部皮肤治疗能够显著促进所有皮肤衰老迹象的临床和主观改善。这种改善在表皮层面表现为通过角质层水合测量和表皮厚度测量显示的水合水平提高,在真皮层面表现为从使用45天起通过皮肤硬度计测量的紧致度和弹性参数得到改善。
所有评估的局部用制剂似乎都是渐进性治疗皮肤衰老迹象的有效选择,因为它们显示出真表皮结构和功能的实际改善以及长期使用的高安全边际。
