Abstract

The invention discloses a light skin-tendering facial mask and a preparation method. According to the facial mask, nonwoven fabric is used as a base material, and a composite material containing photosensitizer is settled and loaded on the surface of the nonwoven fabric, wherein the composite material is a product condensed from sericin, 5-aminolevulinic acid and polyvinyl alcohol / styryl pyridinium in a mass ratio of (3-11):(1-5):(3-7). The preparation method comprises the steps of preparing a photosensitizer solution, coarsely extracting sericin, purifying sericin, preparing the composite material and preparing the facial mask. The light skin-tendering facial mask can be used for improving a rebound effect after light treatment, and improving skin texture, fine lines, pale and yellow face, spots, facial lighting injury and actinic keratosis.

Description

technical field [0001] The invention belongs to the field of cosmetic medicine, and relates to a skin care product, in particular to a light-rejuvenating facial mask and a preparation method thereof. Background technique [0002] Photodynamic therapy (Photodynamic Therapy, PDT) is a new physical and chemical treatment technology developed in recent years. , the latter forms singlet oxygen, free radicals or free radical ions, etc., which act on target cells and cause cell death or apoptosis. PDT has attracted widespread attention due to its advantages of effectiveness, synergy, repeatability and relatively low cost. [0003] 5-Aminolevulinic acid (5-ALA), as an endogenous biochemical substance, is a photosensitive substance that can be used topically. In 1999, the US FDA approved Levulan hydrochloride liniment (Levulan Kerastick, 5-aminolevulinic acid hydrochloride, Dusa Pharmaceuticals, USA) for the treatment of skin actinic keratosis. One of the most active areas of ph...
