Eucalyptus silica

It is obtained by steam distillation of the leaves of the blue gum eucalyptus, which is native to Australia and known for its medicinal properties. It is a natural essential oil without synthetic additives, often used in organic cosmetics for its pure origin. This oil is colourless to pale yellow, with a distinctive camphor-like scent that evokes the freshness of a forest. Traditionally used to clear the airways, it is valued in modern cosmetics for its antiseptic effects. The production process preserves bioactive compounds from the leaves, creating a concentrated product rich in natural essences. Blue gum eucalyptus grows in temperate climates, and its leaves are rich in essential oils. They are harvested at the optimum stage of maturity for maximum effectiveness.

The essential oil has strong antibacterial and anti-inflammatory properties thanks to its main component, eucalyptol (1,8-cineole, 80-91 %), which disrupts bacterial cell walls and regulates sebum production. It soothes irritated skin, reduces redness and provides a cooling effect. It prevents inflammation, cleanses pores and promotes healthy-looking skin. At concentrations of up to 1 %, it is suitable for topical use in cleansers, toners and creams, where it acts as an antiseptic without drying out the skin. It also has antioxidant effects that protect against free radicals.

It is particularly recommended for oily, acne-prone and blemish-prone skin, where it regulates sebum and fights acne-causing bacteria. It is also suitable for combination skin prone to inflammation, or for people who play sport, thanks to its cooling effect on irritated skin. People with very sensitive skin or fragrance allergies should avoid it, as it may cause sensitisation (EU sensitisation index 5 %). Pregnant women and children should use it with caution and always dilute it.

A study published in PMC showed that Eucalyptus globulus essential oil inhibits tyrosinase and melanin production, producing a depigmenting effect and reducing inflammation without irritating the skin (PMC, 2022). Further research confirmed antibacterial activity against MRSA and anti-inflammatory effects that relieve swelling and pain (Healthline, 2023). At a concentration of 10 μL, it neutralises 55,44 % of ABTS radicals, demonstrating strong antioxidant properties (PMC, 2023). These data confirm its safety when diluted and its potential in dermocosmetics.
