Science
Mechanism of Action
Equus Extract's close resemblance to human sebum allows for efficient absorption, delivering a rich blend of unsaturated fatty acids, including alpha-linolenic acid (omega-3) and linoleic acid (omega-6). These contribute significantly to its natural anti-inflammatory properties and skin conditioning. It forms a robust protective barrier, effectively minimizing trans-epidermal water loss and defending against environmental aggressors. Furthermore, Equus Extract supports collagen synthesis, promoting skin elasticity, and acts as an antioxidant by absorbing UVB radiation and neutralizing reactive oxygen species. Its mild antiseptic and antimicrobial qualities also aid in soothing irritation and supporting minor skin repair.

Key findings
- 01 Topical application of horse oil (100mg lotion) for 7 days on DNCB-treated mice skin exhibited anti-inflammatory benefits, evidenced by reduced erythema and IgE levels, alongside recovery of histopathological indicators like epidermal thickening and hyperkeratosis.
- 02 A 4-week clinical study utilizing Horse Oil-loaded Dissolving Microneedle (HO-DMN) patches demonstrated significant improvements in skin and dermal density, elasticity, and moisturization, with a notable absence of adverse events.

Dusting Analysis
Equus Extract is a multi-functional active ingredient with demonstrated benefits for skin conditioning, moisturization, and barrier repair, making it unsuitable for mere 'dusting' at inactive concentrations in formulations.
The Formula
Formulation
Stability
Due to its lipophilic nature, Equus Extract is best integrated into topical creams or serums. Traditional cream formulations may present challenges in stratum corneum penetration, necessitating advanced delivery systems like dissolving microneedle patches for enhanced efficacy. Refinement processes typically involve vacuum dissolving at temperatures ranging from 35°C to 80°C to minimize degradation of active ingredients and prevent oxidation of unsaturated fatty acids. For stable oil-in-water emulsions, optimal formulation often requires HLB values of 11-12 and surfactant concentrations of 15-20%.
Safety
Safety Profile
Equus Extract (Horse Oil) is generally considered safe for topical cosmetic use, presenting a low risk of sensitization and irritation. Clinical evaluations, including those using horse oil-loaded microneedle patches, reported negligible adverse events. While official safety assessments from CIR, SCCS, or FDA are currently unavailable, its established use and clinical tolerability support its safety profile.
