The invention discloses a freeze-dried essence with a repairing effect and a preparation method, and belongs to the field of skin care products, and the freeze-dried essence is composed of freeze-dried powder and an independent solvent liquid. The freeze-dried powder contains 0.5-3 parts of palmitoyl oligopeptide, 3-8 parts of I-type collagen, 1-5 parts of III-type collagen, 0.1-1 part of chitosan, 1-3 parts of secondary variable-temperature fermentation liquor of betula platyphylla and 2-8 parts of a freeze-drying protective agent; the solvent liquid is prepared from 0.5 to 3 parts of hyaluronic acid and 0.05 to 0.5 part of sodium polyglutamate. The preparation method comprises the following steps: a, adding fermentation liquor after dissolving; b, adding nano liposome and a protective agent; c, quickly freezing to-55 + / -2 DEG C by liquid nitrogen, and preserving heat for 2.5-3.5 hours; d, drying for 9-11 hours under the vacuum of 15-25 Pa and at the temperature of-18 + / -2 DEG C; and e, the temperature is increased to 15 + / -2 DEG C in a stepped mode, vacuum is smaller than or equal to 20 Pa, and drying is conducted for 18- Through scientific formula design, multiple effects of efficient repairing, anti-aging and relieving are achieved.

This invention relates to the field of bio-health technology, specifically a method for preparing and applying a peptide composition. The preparation method includes the following steps: S1, preparation of hydrolyzed fish collagen as a raw material for the peptide composition; S11, enzymatic hydrolysis of fish skin collagen; S12, purification using ion exchange resin; S2, mixing and preparing the peptide composition. The peptide composition prepared by this method is used in skin brightening and spot-fading products, with a peptide content of 0.5-10%. The hydrolyzed fish collagen produced by this invention is highly compatible with palmitoyl oligopeptides without precipitation. Furthermore, this invention uses a 0.22-micron polypropylene membrane for filtration, which uses less water and is more efficient than ultrafiltration or nanofiltration, thus preventing bacterial contamination from prolonged filtration of protein peptides. This invention combines hydrolyzed fish collagen with palmitoyl oligopeptides such as palmitoyl tripeptide-5, resulting in excellent anti-wrinkle activity when applied to skincare products.
