The application provides a multi-layer penetration controlled-release acid preparation and a preparation method thereof, and belongs to the field of cosmetics. The preparation is composed of Aspergillus oryzae fermentation substrate freeze-dried powder, composite alpha-hydroxy acid, salicylic acid, poloxamer 407, polyhydric alcohol and non-ionic surfactant. The freeze-dried powder is obtained by co-fermenting olea europaea leaves and curcuma and refining through ultrafiltration. A temperature-sensitive phase change system is constructed by using poloxamer, so that the product is changed from a liquid state to a gel state at body temperature, and the synergistic controlled release of acid components and bioactive substances is realized. The preparation process adopts low-temperature swelling and vacuum freeze-drying technology, so that the stability of the system and the efficiency of the active substances are ensured. The application significantly reduces the irritation of high-concentration acid, improves the black suppression and repair effect, and is suitable for precise improvement of hyperpigmentation problems such as chloasma.

The present application relates to an antibacterial product based on olive leaf extract, belonging to the technical field of antibacterial care. The product is based on olive leaf extract rich in polyphenol active ingredients, combined with bacteriostatic polypeptides derived from Xenopus laevis as the core active component, to achieve synergistic antibacterial effect. Studies have shown that the combination has rapid and strong inhibitory and killing ability on common pathogenic microorganisms such as Staphylococcus aureus and Candida albicans, and is significantly better than single component. In vitro test results show that the product can achieve strong bacteriostatic and bactericidal effect in a short time, and has certain sustained bacteriostatic ability. Compared with traditional antibiotics or single plant extract, the present application improves the antibacterial efficiency and reduces the risk of drug resistance through the synergistic mechanism of "natural plant matrix + functional polypeptide", and has good safety and microecological friendliness, and is suitable for daily care and infection protection of female reproductive system.

The application belongs to the technical field of exosome application, and discloses an exosome composition for preventing hair loss and fixing hair. The exosome composition is obtained by adding plant exosomes in animal stem cell culture, and it is found that the plant exosomes can significantly promote the secretion of animal stem cell exosomes. On this basis, a scheme for constructing the exosome composition for preventing hair loss and fixing hair is constructed. The exosome composition is obtained by mixing fat stem cell exosomes secreted by fat stem cells treated by curcuma exosomes, urine source epithelial stem cell exosomes secreted by urine source epithelial stem cells treated by olea europaea leaf exosomes and biota leaf exosomes according to weight proportions of 1-2:2-5:2-3. The exosome composition can significantly promote hair papilla cell proliferation, has a significant effect on preventing hair loss and fixing hair, has a large number of plant exosomes, can be regenerated, can significantly reduce the use amount of animal stem cell exosomes, and has a better effect after combination, and has a wide application prospect.
