Aristotelia Chilensis Leaf Extract

Aristotelia chilensis leaf extract comes from the maqui berry plant, native to Chile and long used in traditional Mapuche medicine. The extract is derived from the leaves rather than the more commonly known berries, and contains a range of bioactive alkaloids and polyphenols that give it potential biological activity.

In skincare, it functions as a skin conditioner, meaning it helps to support the skin's texture and overall condition. The alkaloids present in the leaves have shown activity at a cellular level, though research into its specific cosmetic applications remains limited.

Aristotelia chilensis leaves contain alkaloids such as aristoteline and hobartine, alongside polyphenols like quercetin. These compounds are thought to work through multiple pathways: they may interact with cellular receptors and ion channels involved in inflammatory responses, and they can neutralise free radicals through antioxidant action.

However, most research to date has examined the berries or isolated compounds in laboratory settings. How these mechanisms translate to meaningful benefits when the leaf extract is applied topically in finished products is not yet well established.

As Aristotelia chilensis leaf extract is typically a supporting ingredient rather than the main active, it is most effective when used as part of a broader skincare routine. Incorporate it into morning or evening applications as part of a serum, toner, or moisturiser. There is no evidence that higher concentrations deliver proportionally better results, so follow the product instructions and use as directed.
