Science
Mechanism of Action
This extract functions primarily as a powerful antioxidant, neutralizing free radicals and mitigating oxidative stress. Its anti-inflammatory capabilities reduce redness and soothe irritated skin. It actively strengthens the skin's natural protective barrier, minimizing moisture loss and defending against external threats like pollution and UV radiation. Furthermore, it stimulates collagen synthesis, improving skin elasticity and reducing fine lines, and elevates hyaluronic acid synthase mRNA levels for superior hydration. The extract also exhibits beneficial antimicrobial activity.

The Formula
Formulation
Stability
Phytocosmetics containing polyphenols, such as Pinus Pinaster extract, exhibit improved stability at a slightly acidic pH and when stored at low temperatures, which helps preserve its antioxidant activity. To prevent oxidation, particularly in fragrance applications, peroxide levels should be meticulously maintained below 10 millimoles per liter, and the inclusion of additional antioxidants during production is advisable.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not specifically reviewed Pinus Pinaster Leaf Extract. However, information pertaining to related 'Pinus Pinaster bark/bud extract' indicates a potential for dermal sensitization when used in fragrance applications as an IFRA Critical Effect. Formulators should ensure peroxide levels remain below 10 millimoles per liter and may need to incorporate antioxidants to enhance stability and safety.
