Science

Mechanism of Action

This ingredient functions as a potent skin conditioning agent and emollient, promoting exceptional skin softness and smoothness. Derived from squalene, it is deeply absorbed to enhance skin flexibility and deliver substantial hydration. It acts as an antioxidant, diminishing free radical damage and safeguarding skin lipids from UV-induced peroxidation, thereby supporting cellular regeneration, skin tightening, and the reduction of age spots and scars for a more youthful appearance. Furthermore, it aids in repairing sun damage and alleviating symptoms associated with skin conditions such as psoriasis and eczema. The presence of alkylglycerols also contributes to robust skin barrier function by offering protective action against bacterial and fungal infections.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

While rigorous product safety assessments are legally mandated for cosmetic ingredients in Europe, the Cosmetic Ingredient Review (CIR) has not formally reviewed Hydrogenated Shark Liver Oil. Topical application is generally well-tolerated and not commonly associated with adverse reactions such as irritation, redness, itching, or allergic responses; however, individual patch testing is recommended. Information regarding its safety during pregnancy and breastfeeding is currently unavailable. It is crucial to differentiate topical application from oral intake of Shark Liver Oil (SLO), which has been linked to potential increases in cholesterol at high doses (e.g., 1.5 grams daily for 8 weeks) and rare reports of pneumonia or acute toxic hepatitis from oral capsules.
