Problems solved by technology

[0002] Emulsion is the most basic step in skin care. Effective ingredients such as moisturizing, whitening, and anti-aging in the emulsion can be better absorbed by the skin. It is very important to have a good bottle of emulsion. Many emulsions on the market today contain a lot of chemicals Synthetic, long-term use will have certain side effects on the skin, making it difficult for the nutrients in the emulsion to be absorbed, and even cause adverse reactions such as skin inflammation. If it is not selected properly, it will cause immeasurable losses. , there are big problems in the selection and dosage of chemical substances, there are few natural ingredients, and the skin care effect is not good, which needs further improvement

Abstract

A preparation method of a whitening and spot-fading emulsion belongs to the technical field of skin care emulsion preparation. The preparation method comprises the following steps: preparing a licorice extract product, preparing a maca extract product, extracting buckwheat starch, preparing granular cold-water-soluble buckwheat starch, and preparing the emulsion. The prepared emulsion is rich in the licorice extract product and the maca extract product. The main active components of licorice are glycyrrhizic acid and flavones, and the product has excellent whitening spot-fading and anti-ageingeffects. Maca contains polysaccharide ingredients, hyaluronic acid, glucan, bio-saccharide gum and other ingredients. Those ingredients have good moisture retention efficacy, and maca is rich in multiple amino acids and has excellent whitening efficacy.
