Science
Mechanism of Action
The extract contains the proteolytic enzymes papain and chymopapain, which selectively catalyze the hydrolysis of keratin proteins in the stratum corneum, effectively loosening dead skin cells to promote renewal. Concurrently, its high concentration of Vitamins A, C, and E, alongside flavonoids, neutralizes reactive oxygen species (ROS) and inhibits tyrosinase activity to mitigate hyperpigmentation and oxidative damage.

Key findings
- 01 A 5.0% topical formulation demonstrated significant free radical scavenging and anti-aging potential by neutralizing ROS (IJSRT).
- 02 Research on a 3.0% spray gel confirmed optimal antioxidant protection against UV-induced damage while maintaining a skin-compatible pH of 5.67.
- 03 The 2021 CIR Final Report established 0.02% as the maximum safe and effective concentration for leave-on skin conditioning applications.
Transparency
Dusting Analysis
Because the maximum safe limit for leave-on products is exceptionally low (0.02%), many brands include it at negligible trace levels (e.g., 0.001%) purely for marketing claims, as it is a recognizable botanical ingredient.
The Formula
Formulation
Stability
Enzymatic activity is highly thermosensitive; exposure to temperatures exceeding 60-70°C will denature the proteins. Cold-pressed or low-temperature extraction is required to maintain biological efficacy.
Synergies
- Alpha Hydroxy Acids
- Vitamin C
- Niacinamide
Conflicts
- High-heat processing
- Strong oxidizing agents
- Carbomer-based thickeners
Safety
Safety Profile
Maximum concentration is restricted to 0.25% in rinse-off products and 0.02% in leave-on formulations to ensure safety and prevent irritation.
