Science
Mechanism of Action
Eucalyptus Dunnii Leaf Extract operates through a diverse array of bioactive compounds, including polyphenols, flavonoids, terpenoids, and organic acids. It functions as an astringent, helping to reduce the appearance of pores and manage excess oil by unclogging them. Its inherent cleansing, antimicrobial, and anti-inflammatory properties aid in mitigating acne and reducing overall skin inflammation. The extract significantly reinforces the skin's protective barrier by promoting tight junction formation and increasing ceramide levels within keratinocytes, thereby enhancing hydration and water retention, particularly beneficial for dry skin. Furthermore, its antioxidant capacity and potential to inhibit AGE formation and stimulate collagen synthesis contribute to anti-aging effects.

Key findings
- 01 An aqueous crude extract from a related Eucalyptus species significantly improved acne-affected skin by 90% over three weeks when applied daily, with no reported side effects.
- 02 In-vitro tests using a related Eucalyptus extract at 1% and 3% concentrations demonstrated enhanced tight junction formation, indicative of improved skin barrier function.
- 03 Topical application of a general Eucalyptus extract on human subjects increased ceramide levels in keratinocytes, leading to improved water-holding and barrier functions in dry skin.
- 04 Eucalyptus extracts demonstrated anti-aging effects and increased collagen density in rats exposed to UVB light, suggesting potential benefits for skin firmness and elasticity.

Formulation
Stability
Aqueous extracts of Eucalyptus dunnii leaves contain polar compounds such as polyphenols, flavonoids, terpenoids, and organic acids, making them water-soluble. Related aqueous crude extracts have been successfully prepared for skin use at pH 6.
Safety
Safety Profile
The CIR Expert Panel considers Eucalyptus globulus-derived ingredients safe when formulated to be non-sensitizing. While a specific maximum concentration for Eucalyptus Dunnii Leaf Extract is not established, a related aqueous Eucalyptus extract used at 50% in human acne treatment demonstrated no adverse effects. It is important to note that a maximum concentration of 0.4% has been specified for Eucalyptus Globulus Leaf Oil, which is chemically distinct from the leaf extract and has shown a low, but present, risk of sensitization (0.24%-0.6% in patch tests).
