Science
Mechanism of Action
Functions through mechanical abrasion to manually detach dead stratum corneum cells and refine skin texture. Its structural composition, exceeding 90% insoluble fiber, provides a high surface area that naturally adsorbs excess sebum and perspiration, while trace avenanthramides offer secondary anti-inflammatory support.

Key findings
- 01 Journal of Drugs in Dermatology (2010/2012): Confirmed efficacy of oat-derived insoluble fibers as non-irritating physical exfoliants and sebum absorbents.
- 02 Indian Journal of Dermatology (2012): Identified trace phenolic acids in oat structures that mitigate inflammation during mechanical exfoliation.
Transparency
Dusting Analysis
While often used at functional levels in rinse-off scrubs, concentrations below 1% in leave-on products are typically insufficient for noticeable exfoliation or oil absorption, suggesting a marketing-only inclusion.
The Formula
Formulation
Stability
Highly stable across diverse temperatures and pH levels; however, it is insoluble in both water and oil, requiring robust suspending agents like carbomers or xanthan gum to prevent sedimentation.
Synergies
