Science

Mechanism of Action

This extract acts as a powerful antioxidant primarily due to its rich polyphenol content, notably aspalathin and nothofagin, which neutralize free radicals and reduce oxidative stress implicated in photo-aging and environmental damage. Beyond antioxidation, it exhibits significant anti-inflammatory, anti-bacterial, and anti-allergic effects, effectively calming irritation, reducing redness, and managing acne-prone conditions. It contributes to a stronger skin barrier, provides moisturizing benefits, and stimulates cellular regeneration for smoother texture. Additionally, its mineral profile (zinc, magnesium) supports natural healing, collagen synthesis for improved elasticity and firmness, and aids in pore purification and impurity removal. Some forms may also contain alpha hydroxy acids for enhanced skin health.

While a specific clinical finding for antioxidant properties is reported at 0.1% (from supplier data), ingredient formulators commonly utilize Aspalathus Linearis Extract in concentrations ranging from 1% to 3% for broader benefits. If formulated below 0.1%, a product might be 'dusting' if it primarily relies on antioxidant claims based on the cited data.

Stability

To preserve its efficacy, the ingredient should be stored in air-tight and light-proof containers. While a specific optimal pH range for skincare is not established, lower pH values have been observed to enhance the stability of aspalathin in beverage formulations. It is available in both water-soluble cellular and oil-soluble extract forms.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has not formally reviewed Aspalathus Linearis Extract. However, its use is approved by regulatory bodies like the European Cosmetics Regulation, indicating it meets general safety standards for cosmetic applications. It is widely considered safe for topical use, though rare individual reactions (e.g., itching, irritation) may occur in very sensitive individuals. No explicit maximum topical concentration has been set by regulatory bodies, with typical formulation use by suppliers ranging from 1% to 3%. Potential herb-drug interactions associated with high oral intake due to CYP enzyme inhibition are not relevant to its topical cosmetic application.
