Abstract

The invention discloses premna microphylla pectin mask liquid and a preparation method thereof, and belongs to the technical field of skin care products. The premna microphylla pectin mask liquid comprises the following components: premna microphylla pectin polysaccharide, premna microphylla flavone, bioactive peptide, green tea essence, pearl powder, an aloe extract, sodium hyaluronate, nipagin and the balance of water. The preparation method comprises the following steps: mixing and stirring the water with the premna microphylla pectin polysaccharide and the sodium hyaluronate, performing cooling, performing mixing with an aqueous solution of other raw materials in proportion, and performing uniform stirring to obtain the premna microphylla pectin mask liquid. The premna microphylla pectin mask liquid disclosed by the invention has the advantages of oxidation resistance, safety, anti-inflammation effect and collagen repair promotion, can comprehensively deal with skin aging caused by ultraviolet rays by integrating various bioactive components, and effectively relieves damage symptoms such as redness, pruritus, desquamation, collagen loss, pigmentation and the like after the skin is dried in the sun. The preparation method is simple and mild in condition, and has popularization and practical values in the technical field of skin care products.

Description

technical field [0001] The invention relates to the technical field of skin care products, in particular to a bean curd pectin facial mask liquid and a preparation method thereof. Background technique [0002] UVA and UVB in ultraviolet rays are important external factors that cause skin aging and damage. UVA (320-400nm) has low energy and can penetrate deep into the dermis. More than 90% of UV rays in sunlight are composed of UVA, causing chronic UV damage. UVB (280-320nm) can penetrate the epidermis and be absorbed by the upper dermis. It is highly genotoxic and can cause erythema, edema, and oxidative stress, and is the main cause of acute UV damage. The skin is exposed to high-dose UV radiation in a short period of time, and it is prone to acute photodamage, resulting in symptoms such as erythema, fever, pain, and itching, which in turn cause pigmentation and thickening of the epidermis. When the skin is exposed to low-dose UV radiation for a long time, it will show ph...
