Zeolites, a nanoporous material currently being tested in various other fields, can absorb heavy metals into a creamy cosmetic and offer potential for formulators looking to remove these environmental compounds, preliminary data from Italy and Switzerland suggests.

Writing in cosmetics, Pesando et al. said zeolites are already being tested as a way to absorb toxins and improve the results of various medical treatments, and their research aimed to show the viability of zeolites as a cosmetic ingredient to prevent heavy metals from penetrating through the skin .

“Toxic metals are defined by many as ‘silent killers’ because they replace minerals necessary for life in the body, altering biological functions and structures,” said Pesando et al. “Zeoliths are currently attracting a lot of interest for their absorption properties, capable of trapping toxins in the crystal channels.”

What are zeolites
According to Pesando et al, zeolites are a nanoporous material with an aluminosilicate crystal structure that can be derived naturally or synthetically. In less scientific terms, zeolites can act as “molecular sieves”, moderating what molecules might reach on the surface of the skin.

Tortini et al stated that consumers, especially those born after 2000, are interested in both sunscreen products and the environmental impacts of products.

“The formulation of effective and pleasant sunscreens, with a natural, organic, sustainable connotation, is becoming more and more complex due to the scarcity of suitable ingredients”,According to Tortini et al.

Plants from around the world offer potential for botanical and recycled ingredients, and a research team from Malaysia has found that the skin of mangosteens may hold promise for skin care.

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

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

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

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