Update: Click Here to Read our Nuance Facial Serum Review

The beautiful Salma Hayek is reportedly coming out with her own skin care line, a venture she has been thinking about for several years now. The line, called “Nuance,” will launch sometime next year and will be sold at CVS drugstores. Of course, this means it will be affordable; on top of that, it will focus on natural ingredients, specifically ones that are indigenous to Hayek’s native country, Mexico.

Hayek claims that her grandmother died at age 96 with “no wrinkles” and that her mother’s skin is equally flawless, all thanks to certain Mexican beauty secrets that involve special ingredients.

One of these ingredients is tepezcohuite, formally known as mimosa tenuiflora. It is a tree native to northern Brazil and southern Mexico. The Maya people have used the bark of tepezcohuite trees since the 10th century to treat skin abrasions. It is also used to treat burns; in fact, in 1984, the city of San Juanico suffered a terrible gas explosion that killed 500 people and left over 5,000 people with burns, which were treated successfully with tepezcohuite.

In addition to its wound healing abilities, the bark has an antiseptic effect and contains tannins (astringents) and flavonoids, which fight free radicals and inhibit the degradation of collagen and elastin. The bark also has a mysterious regenerative effect on skin and tissue. It has the ability to promote the growth rate of human cells in culture and has been shown to stimulate dermal fibroblast activity. Tepezcohuite inhibits hyaluronidase, an act that protects hyaluronic acid in the skin. Studies show that at a 10% concentration, tepezcohuite can treat eczema and skin inflammation.

Information about mimosa tenuiflora is limited, though. It has not made its presence known in cosmetics (at least, not noticeably) and most of the people talking about it are bloggers or people who are looking for remedies for certain skin ailments. There is no information about the seemingly magical plant on the FDA’s website or on any other sites that list safety information.

One tepezcohuite product that seems to be talked about online quite a bit is Tepezcohuite Pomade Arbol de Vida, which used to be sold on Amazon but is not anymore. According to the only other website I could find that sells it, its ingredients are wonderfully simple: petroleum jelly, tepezcohuite oil, wheat germ oil and rosehip oil.
