L-ascorbic acid has been widely used in cosmetic and dermatological products because of its ability to scavenge free radicals and destroy oxidizing agents. However, it is chemically unstable and can easily be oxidized. The current cosmetic facial masks available in the market are pre-moistened, which means that the aqueous fluid content of the mask may oxidize some of the unstable active ingredients such as ascorbic acid. This work presents an anti-wrinkle nanofiber face mask containing ascorbic acid, retinoic acid, gold nanoparticles, and collagen. This novel face mask will only be wetted when applied to the skin, thus enhancing product stability. Once moistened, the content of the mask will gradually dissolve and release the active ingredients and ensure maximum skin penetration. The high surface area-to-volume ratio of the nanofiber mask will ensure maximum contact with the skin surface and help to enhance the skin permeation to restore its healthy appearance. Electrospun fiber mats may provide an attractive alternative to the commercial facial cotton masks.
抗皱含维生素 C、视黄醇酸、金纳米粒子和胶原蛋白的纳米纤维面膜。这种新型面膜只有在贴在皮肤上时才会被润湿,从而提高产品稳定性。一旦润湿,面膜的内容物就会逐渐溶解并释放出活性成分,确保最大程度地渗透到皮肤中。纳米纤维面膜的高表面积与体积比将确保与皮肤表面的最大接触,并有助于增强皮肤渗透,恢复其健康外观。静电纺纤维垫可能是商业面部棉质面膜的一个有吸引力的替代品。
