Mechanism of Action
EPA primarily supports skin health through its potent anti-inflammatory actions, competing with arachidonic acid to reduce pro-inflammatory eicosanoid production. It actively reduces UV-induced skin inflammation and provides protection against photodamage by inhibiting the expression of Matrix Metalloproteinase-1 (MMP-1), MMP-9, and cyclooxygenase-2 (COX-2), alongside suppressing c-Jun phosphorylation, JNK, and p38 activation. Furthermore, EPA enhances collagen and elastic fiber expression by stimulating transforming growth factor-beta, contributing to anti-aging effects, and helps maintain skin hydration and barrier function by modulating epidermal lipid composition, promoting cell regeneration for supple skin.

Key findings
- 01 Topical application of EPA demonstrably reduced UV-induced epidermal thickening, prevented collagen degradation, and attenuated the expression of UV-induced MMP-1, MMP-9, and COX-2. It also mitigated UV-induced c-Jun phosphorylation, JNK, and p38 activation.
- 02 EPA has shown to decrease UV-induced skin inflammation, including erythema following sun exposure, and in smaller studies, improved symptoms of inflammatory skin conditions like psoriasis.
- 03 In aged human skin, EPA increased collagen and elastic fiber (tropoelastin and fibrillin-1) expression by boosting transforming growth factor-beta, positioning it as a promising anti-skin-aging agent.

The Formula
Formulation
Stability
Eicosapentaenoic Acid, an omega-3 polyunsaturated fatty acid with a pKa of 4.82, is highly susceptible to oxidation. Optimal formulation requires the inclusion of robust antioxidants and protective packaging to ensure stability, particularly within typical skincare pH ranges of 4.5-6.5.
Safety
Safety Profile
No specific Cosmetic Ingredient Review (CIR) or Scientific Committee on Consumer Safety (SCCS) assessment or maximum concentration for topical skincare use has been established. However, EWG Skin Deep rates Eicosapentaenoic Acid as 'LOW' for common concerns including cancer, allergies & immunotoxicity, developmental and reproductive toxicity.
