The #1 drug to avoid, according to science

This is the category that holds the majority of the skin-damaging culprits. Man-made substances such as acrylic, polyester, rayonacetate and nylon treated with thousands of harmful toxic chemicals during production, according to ScienceDaily. In a study from Stockholm University, researchers selected four groups of substances related to health risks and tested them for “occurrence, amount, toxicity and how easily they can penetrate the skin”, and the highest concentrations of two of the substances were found in none other than polyester.

Toxic chemicals aside, synthetics simply don’t breathe, as anyone who has worn polyester on a hot summer’s day knows this well. The fabric also traps odors, which Popular Science explained in an article. Not to go into too much gory detail, but skin bacteria found in sweat feed off chemicals that synthetic fibers can’t absorb, creating an environment for smelly bacteria to grow. All signs point to polyester being the number one worst fabric for the skin.
