Science
Mechanism of Action
This ingredient works by reacting with polyunsaturated fatty acids in the skin, generating 'ozone messengers' such as reactive oxygen species (ROS) and lipo-oligopeptides including hydrogen peroxide (H2O2). These compounds stimulate endogenous hydrogen peroxide production, modulate inflammation, enhance oxygen metabolism, and promote angiogenesis to support skin repair. Its antimicrobial properties derive from disrupting bacterial cell walls and membranes, allowing ozone to penetrate and exert its effects. Additionally, ozone acts as a bio-regulator, normalizing cellular redox balance and influencing cytokine levels.

The Formula
Formulation
Stability
The stability of ozonized linseed oil is significantly influenced by the ozonation process, particularly the size and circularity of the bubbles formed. Concentrated solutions are most stable when stored under cold conditions.
Conflicts
- High concentrations of ozonized linseed oil may lead to skin irritation, rashes, or rapid flaking.
- Requires substantial dilution (typically 10-20 times) within formulations to mitigate potential irritation and reduce its inherent high viscosity.
Safety
Safety Profile
No specific CIR review is available for ozonized linseed oil, though other ozonated oils (e.g., olive, sunflower) are registered under Europe's REACH regulation. While generally well-tolerated with promising results and lower adverse events than standard care, some studies have reported mild burning sensations, pruritus, erythema, and desquamation in a small percentage of users (0.3% to 1.6%). High ozone concentrations are known to induce irritation, rashes, and rapid flaking. In vitro cytotoxicity tests for ozonized sunflower oil showed no cytotoxicity at 0.1 mg/mL, but observed cytotoxicity at 1 mg/mL and 10 mg/mL.
