This invention belongs to the field of daily chemical products technology, and particularly relates to a hair-darkening composition, its preparation method, and its application. The hair-darkening composition provided by this invention is scientifically formulated with acetyl hexapeptide-1 and extracts of Polygonum multiflorum, Epimedium, and Aristolochia debilis root extract and Avena sativa seed extract. Through the synergistic effect of small molecule peptides and multiple plant active ingredients, it achieves multi-target and multi-pathway regulation of melanin production mechanisms. Each active ingredient, under specific ratios, exhibits significant synergistic effects, synergistically promoting melanin synthesis in hair follicles. Compared to single ingredients, it effectively enhances hair-darkening efficacy, providing a stable and efficient technical solution for improving gray hair and restoring its natural color, possessing outstanding practicality and application value.

This invention relates to the technical field of cosmetics, and discloses the preparation and application of a supramolecular composition with moisturizing and soothing effects. Using extracts of kava (PIPER METHYSTICUM) leaf / root / stem, milk thistle (SILYBUM MARIANUM) extract, and oat (AVENA SATIVA) extract as core active ingredients, supramolecular encapsulation and spray drying technologies are employed to encapsulate these poorly soluble soothing active ingredients with an encapsulation material. This solves the technical pain points of poor solubility, low transdermal absorption efficiency, and easy loss of activity of single active ingredients. The encapsulated supramolecular composition can deeply penetrate to the basal layer of the skin, soothe damaged skin barrier, and synergistically exert a powerful moisturizing and soothing effect. When applied to cosmetics, it can nourish the skin from the inside out, replenish skin moisture, enhance skin barrier function, and help the skin restore a hydrated, radiant, smooth, and healthy state. Compared with existing single active ingredients, the supramolecular composition of the present invention has significant advantages such as high transdermal absorption efficiency, strong stability of active ingredients, and synergistic effect. It can be widely used in various skin care products such as creams, lotions, emulsions, and masks, as well as related cosmetic systems such as scalp care and body wash.
