Fight signs of aging with cashew leaf extract, says study



As recently reported by market research and data firm Statista, “the global cosmetic antioxidant market is projected to reach $150.9 million by the end of 2023​,” and has demonstrated steady growth since 2017. More than ever, consumers demand better-performing anti-aging products with more sustainable ingredients to address fine lines, wrinkles, and dullness.

To better meet consumer demand, cosmetics and personal care product manufacturers searching for innovative new topical ingredients should note a recent study examining cashew leaf extract’s efficacy as a cosmetic ingredient. The study examined “the bioactive components of cashew leaf extracts to determine their contents of potential antioxidant, anti-tyrosinase, and anti-collagenase agents as natural sources for skincare products.​”

What is cashew leaf extract?

Belonging to the Anacardiaceae ​family, the cashew tree (Anacardium occidentale​ L.) is commonly found throughout southeast Asia and tropical America. The fruit is edible, and historically, “the leaf, stem and bark extracts are used in traditional medicines to treat inflammation, diarrhea, rheumatic diseases, hypertension, and infectious diseases​,” treatments that were successful due to the plant’s antioxidant and anti-inflammatory properties.

As further detailed in the study, cashew lead extract contains phytochemicals, including “flavonoids, polyphenols, alkaloids, saponins, tannins, coumarin, quinone and cardiac glycoside, indicating the potential bioactivity of plants as antioxidant sources​.” Plants are already used in various applications in cosmetic and personal beauty products, including skin-lightening and anti-aging moisturizers, sunscreens, and cosmetics.
