Science
Mechanism of Action
This ingredient functions by forming stable ozonides upon reaction with the polyunsaturated fatty acids in sesame oil. When applied to skin, these ozonides act as 'ozone messengers', gradually releasing small, controlled amounts of ozone and reactive oxygen species (ROS). This cascade of oxidative reactions triggers several beneficial effects: it exerts broad-spectrum antimicrobial (bactericidal, fungicidal, virucidal) activity by disrupting microbial cell structures, modulates inflammatory responses, stimulates angiogenesis, and promotes tissue repair and oxygen metabolism crucial for wound healing. Furthermore, the transient generation of ROS can activate the skin's intrinsic antioxidant defense systems, a phenomenon known as hormesis.
Research
Clinical Evidence
Medium confidenceFor general skincare, common uses range from 1-5%. Specific clinical efficacy for wound healing was observed with peroxide values (PV) between 700-1500 mEq/1000 g, while 0.8% demonstrated antifungal effects.

Stability
Ozonized sesame seed oil is liquid at room temperature but solidifies when refrigerated. Its stability is optimized at lower temperatures and when protected from light, with some formulations reporting stability for up to 36 months when stored below 25°C in tightly closed, dark containers. Ozonation inherently increases the oil's viscosity and acid value. Formulations often incorporate this ingredient diluted 10 to 20 times, and the integration of a strategic antioxidant system is recommended to further enhance its stability.

Safety
Safety Profile
While systemic ozone therapy is not FDA-approved, topical ozonated vegetable oils, including other types like ozonated olive and sunflower oils, have gained regulatory recognition (e.g., Europe REACH). However, uncontrolled or prolonged ozonation can yield undesirable toxic byproducts such as formaldehyde, hydroperoxides, and epoxides, necessitating precise manufacturing. High concentrations may overstimulate cells, potentially leading to irritation, rashes, or excessive skin flaking. Nonetheless, several studies on topical application of ozonated oils have reported no documented side effects, suggesting safety within appropriate formulation parameters.
