Citrus Australasica Seed Oil

Citrus Australasica Seed Oil is extracted from the seeds of the finger lime, a native Australian citrus fruit. Like other plant seed oils, it contains a blend of fatty acids and polyphenolic compounds that give it both conditioning and antioxidant properties.In skincare formulations, it functions primarily as a skin conditioner and humectant—helping to soften the skin and support hydration—whilst its antioxidant compounds may help protect against environmental stressors.

The oil conditions skin through its fatty acid profile, which mirrors the skin's natural lipids and helps maintain barrier integrity. Its humectant action works by drawing water from the deeper layers of skin to the surface, supporting overall hydration levels.The antioxidant compounds in the oil—primarily polyphenols—are thought to help neutralise reactive oxygen species (free radicals) generated by UV exposure, pollution, and natural metabolic processes. This may help reduce oxidative stress, a key factor in skin ageing and inflammation.

This oil works well in serums, facial oils, and moisturisers where it can be applied to clean skin, either alone or layered under other products. It can be used daily as part of a routine, though those with very oily skin may prefer to use it only in the evening or mix it into a lighter moisturiser rather than apply it neat.

Citrus Australasica Seed Oil is generally well-tolerated and suitable for most skin types. As with any plant oil, patch testing is advisable for those with known sensitivities to citrus or botanical extracts.
