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, a Transparent Additive‐Free Fibrous (TAFF) facial mask is reported for skin moisturizing. The TAFF facial mask consists of a bilayer fibrous membrane. The inner layer is 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 is an ultrathin PA6 fibrous membrane that is highly transparent, especially after absorbing water. The results indicate that the GE‐HA membrane can quickly absorb water and become a transparent hydrogel film. By employing the hydrophobic PA6 membrane as the outer layer, directional water transport is achieved, which enables TAFF facial mask with excellent skin moisturizing effect. The skin moisture content is up to 84% ± 7% after placing the TAFF facial mask on the skin for 10 min. In addition, the relative transparency of the TAFF facial mask on the skin reaches 97.0% ± 1.9% when ultrathin PA6 membrane is used as the outer layer. The design of the transparent additive‐free facial mask may serve as a guideline for developing new functional facial masks.

“…emblica, Huangshui, and grape seed extract, etc. These nanofibers dissolve upon contact with moisture, facilitating nutrient absorption. , For dry masks, the Janus structure has been found to prevent water suck-back and delay water evaporation. , The Janus fabric’s inherent asymmetry enables the achievement of diode-like directional water transport (DWT). ,, This is made possible by incorporating external hydrophobic (HP) and internal HL domains, known as the primary and most effective method for creating Janus structures. − This unique structure has also been applied in various areas, including moisture-wicking fabrics, − electronic skin, , desalination, − and wound dressing. − However, the Janus structure constructed by electrospinning still has the problem of easy peel-off, crack, or falloff during storage due to the poor mechanical strength of HL nanofibers. Electrospraying is also an effective method of storing nutrients, which can be used to encapsulate active substances by forming microspheres, and the solvent usually has low viscosity, which is conducive to long-term storage, transportation, and processing.…”
