What Is Cymbopogon Citratus (Lemongrass) Leaf Oil?

Also known as Oil of Verbena. As a volatile fragrant oil, it contains compounds (including limonene and citral) that can cause sensitivity when applied to skin. For more information, see the entry for Cymbopogon Citrates.

How It Works

The antioxidant effects of lemongrass oil are attributed to its volatile compounds, particularly citral. In laboratory assays, these compounds demonstrate the ability to neutralise free radicals and inhibit lipid peroxidation—a process that can damage skin cells and contribute to ageing. However, most of this evidence comes from in-vitro studies, so the extent to which these benefits translate to living skin remains unclear.

The antimicrobial activity appears to work through the oil's chemical constituents interfering with the growth and biofilm formation of certain microorganisms. Again, most research has been conducted in controlled laboratory settings rather than on human skin, so practical efficacy in skincare products requires further investigation.

Clinical Evidence & References

In-vitro studies show that lemongrass oil exhibits antioxidant activity comparable to some established antioxidants, and demonstrates antimicrobial and antifungal properties in laboratory conditions. One study explored its use in a microemulsion-based hydrogel formula for acne treatment, showing promising formulation characteristics, though human efficacy data were not reported. Another investigation examined its potential to inhibit fungal biofilm formation on medical devices.

What is important to note is that most evidence is laboratory-based. Human clinical trials investigating the skin benefits of lemongrass oil in topical formulations are limited, so we cannot yet confidently state how effective it is when applied to skin in real-world conditions. The concentrations used in research may also differ significantly from those found in cosmetic products.

How to Use

Lemongrass oil is typically used in very low concentrations in skincare formulations, so it is unlikely to be an active treatment on its own. It works best as part of a broader formulation with other well-established skincare ingredients. If you are incorporating a lemongrass-containing product into your routine, use it as directed on the product label—usually daily or as tolerated. Patch test first if you have sensitive skin or are prone to irritation.

Safety & Precautions

Lemongrass oil is generally well-tolerated when used in cosmetic concentrations. However, it is listed as a fragrance allergen in EU regulations, so individuals with fragrance sensitivity or known citral sensitivity should avoid it or patch test first. Essential oils can be irritating if used at high concentrations or on broken skin.
