Science
Mechanism of Action
Sourced from Australian Desert Lime, this powder delivers a robust spectrum of antioxidants, including Vitamin C, phenolic acids, flavonone glycosides, lignans, and coumarin derivatives, which effectively protect skin cells from damaging free radicals and environmental aggressors. Its humectant properties actively draw and retain moisture, promoting optimal skin hydration. The inherent Vitamin C content stimulates collagen synthesis, supporting skin firmness and elasticity. Furthermore, the natural presence of citric acid facilitates gentle exfoliation, encouraging cellular renewal for a smoother, brighter complexion and a reduction in the appearance of dark spots. It also exhibits soothing properties, helping to mitigate redness and irritation.

Dusting Analysis
While present at low concentrations (up to 0.0051% for the extract), this ingredient delivers tangible benefits through its potent antioxidant, humectant, and exfoliating properties, indicating it is not typically used merely for 'dusting' purposes.
The Formula
Formulation
Stability
As a hygroscopic powder, Citrus Glauca Fruit Powder is prone to caking and clumping when exposed to humidity, often necessitating the inclusion of carriers or anti-caking agents to maintain dispersibility. Fine particle sizes can hinder dissolution, whereas partially agglomerated powders tend to dissolve more readily. Vigorous mixing of concentrated solutions may induce foaming. For optimal preservation of freshness and aromatic qualities, storage below 30°C in tightly sealed containers, shielded from direct sunlight, is recommended.
Safety
Safety Profile
The independent Cosmetic Ingredient Review (CIR) Panel has deemed Citrus Glauca Fruit Extract safe for use in cosmetics, with reported concentrations ranging from 0.003% to 0.0051%. However, the CIR emphasizes that formulations incorporating citrus fruit-derived ingredients must be meticulously designed to be non-irritating and non-sensitizing due to their potential volatile components. For leave-on products, a critical guideline is that the formulation should not contain more than 0.0015% (15 ppm) of 5-methoxypsoralen (5-MOP). This ingredient is also Generally Recognized As Safe (GRAS) by the FDA for food applications.
