Composition for promoting metabolism of aged skin as well as preparation method and application of composition

Abstract

The invention belongs to the technical field of cosmetics, and discloses a composition for promoting metabolism of aged skin and application of the composition. The composition for promoting metabolism of the aged skin is prepared from, by weight, 0.1-1 part of peach blossom extract and 1-3 parts of lactobacillus leavening, and a preparation method of the peach blossom extract comprises the steps that fresh peach blossoms are dried and smashed, an ethanol solution is added, ultrasonic-assisted extraction and filtration are conducted, a clarifying agent is added into filtrate, standing and centrifugation are conducted, supernate is collected and concentrated under reduced pressure, and the peach blossom extract is obtained. Adding a solvent, uniformly stirring, filtering by using a microfiltration membrane and an ultrafiltration membrane in sequence, and collecting filtrate, thereby obtaining the product. The preparation method of the lactic acid bacteria fermentation product comprises the following steps: inoculating lactic acid bacteria to an MRS liquid culture medium, carrying out shake cultivation, then carrying out sterilization and centrifugation, collecting lactic acid bacteria, washing with sterilized distilled water, re-suspending the bacteria in the sterilized distilled water, carrying out wall-breaking treatment to release nutrient substances, filtering, and collecting filtrate, thereby obtaining the lactic acid bacteria fermentation product. The composition can improve aged skin from the dimensions of promoting epidermal renewal and regulating skin protein metabolism balance.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a composition for promoting aging skin metabolism, its preparation method and application. Background technique [0002] Generally speaking, after the age of 25, the skin begins to show signs of aging, and external harmful factors often accelerate the aging process. In aging skin, the renewal of epidermal cells is slowed down, the barrier function is weakened, and the repair ability of the epidermis after injury is weakened, resulting in dry skin, desquamation, and wrinkles. In addition, the number of fibroblasts in the dermis of aging skin will gradually decrease, the ability to synthesize collagen and elastin will decrease, and the deposition of damaged proteins will increase. The most intuitive manifestations are wrinkles, relaxation, and pigmentation. [0003] Research on delaying skin aging has always been one of the focuses of the cosmetics industry. There are many theor...

Problems solved by technology

[0006] There are many products on the market to prevent and delay aging, but the main point of entry is aging caused by external factors. Most of the products use α- or β-hydroxy acids or enzymes. Frequent use of these substances will destroy the stratum corneum of the skin, and then the keratin Thinning of the layer causes the skin to become more sensitive
