write in Beauty products, 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”,According to 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.
This unusual shape has led zeolites to appear in pharmaceutical research, the biomedical field, agriculture, zootechnical fields and in the treatment of skin conditions or lesions such as skin ulcers, surgical incisions and psoriasis.
“Zeolith has excellent properties of absorption, radiation protection, decontamination, detoxification in the human body, but also has the advantage of introducing, by ion exchange, minerals essential to life”,According to Pesando et al.
Dangers of heavy metal exposure
Heavy metals can be encountered in a number of types of pollution, including air, water and soil pollution, and sometimes appear in jewelry and cosmetics, Pesando et al said.
According to an article by Frontiers of pharmacology,Exposure to the heavy metals mercury, lead, chromium, cadmium and arsenic can affect many organs and systems, which can lead to gastrointestinal and renal dysfunction, nervous system disorders, skin damage, vascular damage, dysfunction of the immune system, birth defects and cancer.
Pesando et al stated that the skin is the main area of the body where heavy metals accumulate.
Promising results, more research needed
Research by Pesando et al showed that a creamy skin care formulation containing 3% zeolite powder had “significant performance” in absorbing both nickel and cadmium, although they stated that they did not yet know what chemical mechanisms are at play to increase absorption.
Additionally, Pesando et al stated that it may be possible to adapt zeolites for targeted application, possibly giving them broader and more specific use in protective skin care.
“In fact, zeolite appears to show promise for wound healing, blood clotting, antibacterial properties, and skin regeneration,”According to Pesando et al. “Furthermore, the possibilities of designing zeolite structures by computer simulation methods could improve and amplify zeolite performance and applications.”
The research team said more research needs to be done on the potential benefits of zeolites to human health and blending zeolites to enhance heavy metal absorption, allowing for clinical customization of the ingredient.
