No. The plant extracts in Ultra Veil have not been shown to prevent skin cancer. It is interesting to note, however, that four extracts in Ultra Veil (Phellinus linteus, Scutellaria baicalensis, Thymus serpyllum, and Aspalathus linearis) are considered to have possible anti-cancer properties. Even more intriguing, data from a 2007 Korean university study suggests that Scutellaria baicalensis may have the potential to inhibit development of skin cancer. Nevertheless, there is no concrete clinical evidence at this time that the extracts in Ultra Veil prevent skin cancer and Amarte does not make this claim. While this concept is an intriguing theoretical possibility, Amarte wishes to be perfectly clear in stating that the extracts in Ultra Veil have not been clinically proven to prevent skin cancer and are not intended to further reduce the risk of skin cancer that users can reasonably expect when applying Ultra Veil per FDA guidelines.
