What Is Ozonized Oleic Acid?
Ozonized oleic acid is a modified form of oleic acid, a naturally occurring fatty acid found in plant and animal oils. The ozonisation process alters the chemical structure of oleic acid by introducing ozone, which changes how the ingredient behaves in formulations and on skin.
In skincare products, it functions as an emollient and skin protectant, helping to soften the skin surface and support barrier function. The modification process is intended to enhance its stability and efficacy compared to standard oleic acid.
How It Works
Ozonized oleic acid works primarily as an emollient, meaning it sits on the skin surface and in the outer layers to reduce water loss and soften the stratum corneum (the outermost skin layer). The ozonisation process is thought to enhance the ingredient's ability to interact with skin lipids, potentially improving its barrier-protective properties.
Clinical Evidence & References
Published research on ozonized oleic acid in skincare is limited. One case study describes its use as part of a multi-ingredient topical treatment for a severe non-healing wound in a patient with a rare genetic condition, where it showed promising results alongside other active ingredients and complementary therapies. However, this is a single case and does not establish efficacy for routine skincare use.
Further evidence is needed to determine its effectiveness for common skin concerns and how it compares to standard oleic acid or other emollients in typical formulations.
How to Use
Ozonized oleic acid is typically found in leave-on products such as creams and serums. Apply to clean, damp skin to optimise hydration. It works well alongside humectants (such as glycerol) and can be layered with other treatments. If using in a formulation with active ingredients, apply after water-based products but before or mixed with heavier creams.
