Science
Mechanism of Action
This ingredient functions as a stable reservoir for ozone and its oxidized derivatives, which are gradually released to stimulate the skin's inherent regeneration processes. It maintains glycerin's natural humectant capability, attracting and retaining moisture for optimal hydration. Ozonized glycerin exhibits potent antimicrobial effects by disrupting the lipid layers and proteins of bacterial, fungal, and viral cell membranes. On the skin, it diminishes age spots through oxidative bleaching and by downregulating melanin synthesis. It enhances cellular metabolism by upregulating genes crucial for keratinocyte differentiation, activating the Nrf2 pathway, and fostering the production of key structural components like collagen, hyaluronic acid, and ceramides, thereby supporting skin repair and elasticity. Additionally, it helps to mitigate inflammatory responses and possesses astringent qualities that can refine skin texture and modulate oil production.

Key findings
- 01 Regular application of an 0.008% (80 ppm) ozonized glycerin formulation significantly improved the appearance of age spots on human facial skin after 8 weeks.
- 02 An 0.08% (800 ppm) formulation demonstrated superior efficacy in reducing melanin content on human facial age spots over 8 weeks compared to the 0.008% concentration, alongside exhibiting higher direct melanin degradation in vitro.
- 03 An ozone gel formulation, at concentrations ranging from 62.5 to 500 µL/mL, effectively inhibited the growth and biofilm formation of diverse bacterial and yeast strains.
- 04 As low as 6 µL/mL of an ozone gel formulation significantly reduced TNF-α production in human peripheral blood mononuclear cells, indicating potent anti-inflammatory activity.
- 05 An ozone gel formulation at 5-10 µL/mL enhanced regenerative processes, accelerating wound closure in human dermal fibroblasts and keratinocytes.
- 06 Concentrations exceeding 0.1% (>1000 ppm) achieved substantial viral inactivation (≥94.38%) of SARS-CoV-2 within 20 seconds, highlighting its potent disinfectant capabilities.

Dusting Analysis
Ozonized glycerin is a multifaceted active ingredient with clinically supported benefits across multiple skin concerns, making it a key component in precision formulations rather than a 'dusting' ingredient.
The Formula
Formulation
Stability
For optimal preservation of its oxidizing power, ozonized glycerin formulations are typically stable for over 2 years when stored refrigerated at 2°C to 8°C (36°F to 46°F) and protected from light and heat. While some patented formulations achieve 3-year shelf stability without refrigeration and remain odorless, refrigeration is generally recommended. Freezing is not advisable. The purity of the base glycerin is critical; research-grade glycerin (99.5% or higher) is essential to prevent unpredictable reactions with ozone and the formation of potentially harmful byproducts.
Safety
Safety Profile
Extensive animal studies have shown no signs of toxicity. Human clinical trials involving daily facial application of an 0.08% (800 ppm) formulation for two months revealed no adverse effects. Cosmetic products featuring ozonized glycerin have been available since 2004, including those for atopic dermatitis and sensitive skin, with no reported side effects, supporting its low irritancy profile. However, concentrated ozonized glycerin presents a very low pH (approximately 2) and hypertonic properties, necessitating careful dilution and buffering to a neutral pH (e.g., with sodium bicarbonate) for safe and effective topical application.
