Skin to skin: Potential benefits of upcycled mangosteen peel extract, study – USA

The research team, Tan et al, was recently published in Cosmetics exploring the potential of mangosteen peels as a cosmetic ingredient, both because of its skincare properties, upcycling potential and impact on local economies.

Mangosteen is a sweet, juicy fruit cultivated mainly in Southeast Asia, particularly Malaysia. The fruit is often processed into juices, concentrates and dried fruits for consumption, leaving behind waste like peels.

Tan et al used mangosteen peels to create an upcycled, standardized extract with potential anti-aging, antioxidant, anti-wrinkle and pigmentation control effects.

“Natural antioxidants derived from natural sources such as mangosteen peel are preferable to synthetic antioxidants due to the undesirable side effects of synthetic antioxidants,”​ Tan et al said. “Hence, the objective of this study is to formulate and evaluate novel herbal face creams containing mangosteen peel extract that was standardized.”

Potential as active botanical

Antioxidant ingredients are commonly used to fight free radicals and mitigate their skin aging effects. Tan et al also said botanical ingredients may be preferable to synthetic ones to avoid adverse effects like skin dryness and irritation.

The research team found that their mangosteen peel extract had stronger antioxidant capacity compared to ascorbic acid, butylated hydroxytoluene and Trolox. Tan et al said, particularly compared to BHT’s possible skin irritation and pulmonary toxicity, mangosteen peel extract is relatively safe and effective.
