Science
Mechanism of Action
The efficacy of salmon oil is rooted in its rich profile of omega-3 fatty acids, predominantly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These fatty acids are readily incorporated into cellular membranes, where they modulate the production of inflammatory mediators and strengthen the skin’s natural barrier function. EPA acts as a potent antioxidant, exhibits anti-inflammatory properties, and aids in regulating sebum production, while DHA is a vital structural component for maintaining healthy cell membranes. This lipid replenishment improves moisture retention, enhances skin elasticity, and alleviates irritation. Additionally, the presence of vitamins A, D, and E contributes antioxidant protection against environmental free radical damage.

Key findings
- 01 Products incorporating salmon oil within a 0.1-0.5% concentration range are commonly utilized as general and eye moisturizers, indicating benefits for skin hydration and repair.
- 02 General fish oil supplementation, both oral and topical, has demonstrated a reduction in skin inflammation, improved hydration, enhanced skin barrier function, increased elasticity, and some protective effects against UV radiation. Specific benefits observed include decreased hyperpigmentation, alleviation of dry skin and dermatitis-related itching, and accelerated wound healing.

Formulation
Stability
Omega-3 fatty acids are highly susceptible to oxidation and isomerization, which can diminish their effectiveness. Therefore, formulations require co-formulation with antioxidants, such as butylated hydroxyl anisole (BHA), butylated hydroxyl toluene (BHT), or alpha-tocopherol, to ensure long-term stability. While oils lack an intrinsic pH, the optimal pH range for a final product containing salmon oil aligns with the skin's physiological acidic mantle (pH 4.5-5.5) for barrier integrity and product efficacy.

Safety
Safety Profile
While individual fatty acid components (e.g., linoleic acid) have undergone CIR review and are deemed safe at non-irritating, non-sensitizing concentrations, a specific safety assessment for 'SALMON OIL' as a cosmetic ingredient by CIR or SCCS has not been conducted. Salmon oil meets U.S. Federal Food, Drug, and Cosmetic Act standards as a food-grade ingredient.
