A Transparent Additive-Free Fibrous Facial Mask for Skin Moisturizing.

Abstract

Most sheet facial masks for skincare are made of nonwovens and loaded with liquid active ingredients, which are usually opaque and require additives for long-term preservation. Herein, we report a Transparent Additive-Free Fibrous (TAFF) facial mask for skin moisturizing. The TAFF facial mask consists of a bilayer fibrous membrane. The inner layer was fabricated by electrospinning functional components of gelatin (GE) and hyaluronic acid (HA) into a solid fibrous membrane to get rid of additives, the outer layer was an ultrathin PA6 fibrous membrane which was highly transparent, especially after absorbing water. Our results indicated that the GE-HA membrane could quickly absorb water and became a transparent hydrogel film. By employing the hydrophobic PA6 membrane as the outer layer, directional water transport was achieved, which enabled TAFF facial mask with excellent skin moisturizing effect. The skin moisture content was up to 84%±7% after placing the TAFF facial mask on the skin for 10min. In addition, the relative transparency of the TAFF facial mask on the skin reached 97.0%±1.9% when ultrathin PA6 membrane was used as the outer layer. Our design of the transparent additive-free facial mask may serve as a guideline for developing new functional facial masks. This article is protected by copyright. All rights reserved.
