Science
Mechanism of Action
This ingredient operates by forming a surface barrier that effectively slows water loss and provides temporary protection to skin that is injured or exposed. Its high concentration of omega-3 fatty acids (EPA and DHA) is integral for maintaining skin barrier integrity, reducing inflammation by inhibiting immune cell migration and lowering inflammatory markers, thereby calming irritation and redness. Vitamin A within the oil promotes skin renewal, supports epithelialization, and stimulates new cell production. Additionally, Gadi Iecur Oil exhibits antioxidant properties that combat oxidative stress, and its fatty acid extracts have demonstrated specific antibacterial activity against Gram-positive bacteria, alongside potential antifungal and antiviral benefits.

Key findings
- 01 Topical application of a 25% cod liver oil ointment significantly accelerated the healing of wounds in hairless mice, enhancing both the epithelial and vascular components. This effect is largely attributed to its Vitamin A content.
- 02 A fatty acid extract derived from cod liver oil demonstrated antibacterial efficacy against Gram-positive bacterial strains (MICs 128–512 μg/mL) in an in-vitro setting, though no activity was observed against Gram-negative strains.

The Formula
Formulation
Stability
Gadi Iecur Oil presents as a pale yellow oily liquid, which can be refined to remove its characteristic mild fishy scent, allowing for odor-free formulations. When incorporated into ointments with waxes, it forms pharmaceutically acceptable compositions that are less greasy and maintain adherence to the skin, with waxes also contributing to increased viscosity. Topical formulations containing fatty acid extracts from this oil typically show an acidic pH range of 4.2-5.6, which is generally suitable for dermal application.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deferred its evaluation of Gadi Iecur Oil, acknowledging that its safety has been robustly assessed by the FDA. The FDA permits its use as an active ingredient in Over-the-Counter (OTC) skin protectant drug products at concentrations ranging from 5% to 13.56%. In Europe, its use in cosmetics is permissible under the general provisions of the Cosmetics Regulation, provided it adheres to animal by-products regulations. While some information regarding specific topical side effects is limited, SkinSAFE categorizes Cod Liver Oil as 'Teen SAFE', 'Baby SAFE', 'Eyelid SAFE', 'Irritant Free', 'Fragrance Free', 'Paraben Free', and 'Common Preservative Free'. However, it is important to note that excessively high topical levels of its intrinsic Vitamin A content could potentially induce skin dryness or irritation.
