Science
Mechanism of Action
Ginkgo Biloba Leaf Extract functions as a powerful antioxidant, actively defending the skin from free radical damage induced by UV rays and pollution, thereby helping to prevent premature aging. It also exhibits anti-inflammatory and soothing effects, improves microcirculation for a radiant complexion, and supports collagen production to enhance skin elasticity and minimize fine lines. Linum Usitatissimum Seed Extract nourishes the skin with Omega-3 fatty acids, antioxidants, and vitamins, promoting deep moisturization and strengthening the skin barrier. Its alpha-linolenic acid content reduces inflammation and irritation, while its mucilage forms a protective, moisture-retaining film, fostering regeneration and a smooth, healthy texture.

Key findings
- 01 Clinical evaluations of cosmetic formulations containing Ginkgo Biloba Leaf Extract at concentrations up to 1.5% have reported no adverse effects.
- 02 Ginkgo Biloba Leaf Extract is typically incorporated into cosmetic products at levels ranging from 0.5% to 3%.
- 03 A semisolid formulation of Linseed oil (derived from Linum Usitatissimum Seed) applied topically at 1% or 5% concentration achieved 100% reepithelialization in excisional rat wounds, demonstrating significant regenerative potential.

Stability
Optimal stability for both Ginkgo Biloba Leaf Extract and Linum Usitatissimum Seed Extract is observed within a pH range of 4.5 to 6.5. Linum Usitatissimum Seed mucilage polymers are sensitive to pH, with studies indicating best yield near neutral pH (6.75). Formulators should also note that any significant oil components derived from Linum Usitatissimum Seed are prone to oxidation, especially under high heat conditions.
Conflicts
- Ginkgolic acid impurities in Ginkgo Biloba Leaf Extract must be controlled to a maximum of less than 5 ppm.
- Potential for oxidation if the extract contains substantial Linum Usitatissimum Seed oil components and is exposed to high temperatures.
Safety
Safety Profile
The CIR Expert Panel concluded that Ginkgo biloba leaf-derived ingredients, including the extract, are safe in cosmetic applications when formulated to be non-sensitizing. The maximum reported leave-on cosmetic use concentration for Ginkgo Biloba Leaf Extract is 0.24%. Adherence to good manufacturing practices is crucial to limit ginkgolic acid impurities to below 5 ppm. Linum Usitatissimum Seed Extract is generally well-tolerated, demonstrating exceptionally low risks of irritation or allergic reactions, and is considered non-comedogenic. However, it's important to distinguish this from Linum Usitatissimum Seed Oil (flaxseed oil), which can exhibit moderate comedogenicity (rating 4) when used in high amounts. The FDA has not approved Ginkgo Biloba for therapeutic indications, and a specific SCCS status for the combined extract is not currently available.
