Science
Mechanism of Action
The horse fat component, with a fatty composition closely resembling human sebum, is readily absorbed, facilitating deep moisture delivery and creating a protective barrier against transepidermal water loss. It supplies essential fatty acids, such as linoleic acid, for anti-inflammatory benefits, alongside vitamins A, E, and F to support skin metabolism, promote collagen synthesis, and improve elasticity. The fermentation process by Lactobacillus further contributes to a balanced skin microbiome, activates micro-ecological activity, inhibits harmful bacteria, and strengthens the skin cuticle. Lactobacillus extracts also stimulate the production of beta-defensins, integral to the skin's natural defense system.

Key findings
- 01 A human skin primary irritation test confirmed the hypoallergenic nature of fermented horse oil products, demonstrating their safety for topical application. The fermentation process significantly increased α-glucosidase inhibitory activity and reduced pathogenic bacteria, with *Lactobacillus acidophilus* constituting 95.2% of the microbial community after 10 days.
