Eucalyptus Radiata Leaf/Stem Extract is a versatile botanical ingredient utilized for its broad spectrum of skin benefits.

Antimicrobial Anti-inflammatory Antioxidant Oil-regulating Purifying Decongesting Soothing Barrier support Anti-aging Depigmenting Masking Perfuming

Science

Mechanism of Action

Eucalyptus Radiata Leaf/Stem Extract functions through several pathways to enhance skin health. For oily skin, it provides purifying and decongesting effects, aiding in sebum regulation. It supports the skin barrier and moisture levels by potentially stimulating ceramide production within the epidermis. The extract also exerts cooling and anti-inflammatory actions, which can reduce redness and discomfort. Furthermore, its rich composition of tannins, saponins, and flavonoids may contribute to anti-aging benefits by promoting collagen density. The essential oil components, notably 1,8-cineole, underpin its demonstrated antimicrobial efficacy against various bacteria. Related Eucalyptus species have also shown in vitro anti-aging (reducing senescence markers, upregulating collagen type 1) and depigmenting (tyrosinase and melanin inhibition) activities.

Safety

Safety Profile

CIR Status
Safe with restrictions
Max tested
0.4%
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Eucalyptus-derived ingredients are safe in cosmetics with restrictions, with a maximum concentration of 0.4% for leave-on products (based on Eucalyptus Globulus Leaf Oil, serving as a general guideline). However, Eucalyptus radiata essential oil contains components like eucalyptol (1,8-cineole, up to 75%) which can be irritating and cause allergic skin reactions. Careful formulation is essential to remain non-sensitizing and adhere to IFRA restrictions for components like citral and geraniol.
