This invention discloses a bio-dress containing multiple anti-aging factors and its preparation method. The bio-dress, by weight percentage, comprises 1-10% collagen solution, 2%-15% styraxine, 0.5%-8% ergothioneine, 1%-12% ectoine, and auxiliary ingredients. This bio-dress integrates multiple anti-aging factors, and through the synergistic effect of these factors, it can effectively improve skin aging problems. It is suitable for medical aesthetics and daily skincare, possessing good anti-aging effects and skin safety.

This invention provides a method and application for preparing biological dressings using a combination of enzymes. The preparation method includes static water thawing; dehairing and degreasing; cutting and segmenting; fine trimming and perforation; iodine immersion treatment; purified water immersion treatment; trypsin and neutral protease solution immersion treatment; purified water immersion treatment; antibacterial coating treatment; packaging; and irradiation. This invention significantly improves the antigen removal rate through the combined use of two enzymes. The combined use of these two enzymes enables comprehensive and efficient degradation of different types of heterogeneous proteins, forming a complementary enzymatic process. The combined use of two enzymes can greatly increase the antigen removal rate, significantly improve the biocompatibility of the biological dressing, reduce the risk of immune rejection in clinical applications, and the prepared biological dressing has good biocompatibility and suitable clinical applicability.
