Everyone knows that smoking can worsen wrinkles, but a new discovery by Italian scientists could put tobacco in a new anti-wrinkle role.
Chosen because of its levels of proline and glycine, abundant amino acids in human collagen, wild tobacco was tested on keratinocytes and fibroblasts to determine its anti-aging properties. In addition to acting as an antioxidant, the researchers found that its mix of peptides, amino acids and sugars had an impact at the genetic level.
Tobacco was found to improve the expression of aging-influential sirtuins, while also increasing the cellular response of genes connected to collagen synthesis. Additionally, it inhibits MMPs from breaking down collagen.
Further tests will be performed to confirm tobacco’s anti-aging power, but its sugar-peptide extract is already available in a handful of products as an ingredient called Bionymph.
