People strive to maintain the best look and have a youthful appearance. The skin around the eye is an area without many oil glands and collagen in comparison to the body rest, so it is more prone to fine lines and dehydration, which makes it look dull. The aim of this research is to develop and evaluate in vivo efficacy of an anti-wrinkle and dark circle eye pad consisting of 3% w/w caffeine and 1% vitamin K in a convenient, healthy, and cosmeceutical base.
Pre-emulsions containing selected ingredients in a specified effective concentration were prepared. The selected formulation, based upon pharmaceutical parameters, was coated on a nonwoven fabric in an eye counter shape, and stored in a jar. Then in vivo trial was carried out for investigation of its anti-wrinkling efficacy on 11 healthy women. In a single blind trial, the sample pad was applied under the right eye and the placebo pad, consisting of water, was placed under the left eye simultaneously. The efficacy and safety of the formulation was evaluated visually and with a multi skin test MC 900 instrument.
After four weeks, the skin around the right eye of all the subjects experienced a reduction in the depth of wrinkles and dark circles, and from a subjective point of view, the appearance and elasticity of the skin were improved.
The caffeine pad containing vitamin K in an Emu oil base shows an improvement in eye counter appearance with anti-dark circle capacity and as an emollient.
人们努力保持最佳容貌和年轻外观。与身体其他部位相比,眼周皮肤的皮脂腺和胶原蛋白较少,因此更容易出现细纹和脱水,从而显得暗沉。本研究的目的是开发并评估一种抗皱、去黑眼圈眼贴的体内功效,该眼贴由3%(重量/重量)咖啡因和1%维生素K组成,采用方便、健康的药妆基质。
制备含有特定有效浓度所选成分的预乳液。根据药学参数,将所选配方以眼贴形状涂覆在无纺布上,并储存在罐中。然后对11名健康女性进行体内试验,以研究其抗皱功效。在单盲试验中,将样品眼贴贴在右眼下方,同时将由水组成的安慰剂眼贴贴在左眼下方。通过视觉和使用多皮肤测试MC 900仪器评估该配方的功效和安全性。
四周后,所有受试者右眼周围的皮肤皱纹深度和黑眼圈均有所减轻,从主观角度来看,皮肤的外观和弹性得到了改善。
含有维生素K的鸸鹋油基咖啡因眼贴在改善眼周外观方面具有去黑眼圈能力,并可作为润肤剂。
