Science
Mechanism of Action
It acts as an ALA delivery vehicle, converting into Protoporphyrin IX (PpIX) within the skin. Under specific light exposure, PpIX generates reactive oxygen species, selectively targeting C. acnes and modulating sebaceous gland activity, while also offering antioxidant benefits.

Clinical Evidence
High confidence0.5%
Key findings
- 01 At 0.1-0.5%, it demonstrated significant antimicrobial activity against C. acnes and Staphylococcus aureus.
- 02 When activated by blue (415nm) or red (630nm) light at 0.01-1.0%, it notably reduced sebum production and inflammatory acne lesions.

The Formula
Formulation
Stability
This ingredient is heat and light-sensitive, requiring storage in dark, cool conditions. Formulations should be opaque or UV-protected as it degrades above 40°C or at extreme pH levels.
Conflicts
- Strong oxidizing agents
- High concentrations of ethanol
- Direct UV light exposure during storage
- Extreme pH (below 4 or above 7)
Safety
Safety Profile
Generally considered safe at 0.001%-1%, but as an ALA derivative, it carries a risk of photosensitivity if used without controlled light parameters. It is listed in EU Cosing and PCPC INCI inventory.
