The ability of our skin to protect us from chemicals is something we inherit. Some people are less well-protected which could imply an increased risk of being afflicted by skin disease or cancer. A new study from Karolinska Institutet in Sweden that has been published in Environmental Health Perspectives shows how the rate of uptake of common chemicals is faster in people with a genetically weakened skin barrier.
We are continually exposed to chemicals from many different sources, for example, food, hygiene products, cosmetics and textiles. Many people are also exposed to chemicals at their place of work which can constitute a work environment problem.
The protein filaggrin is important for the structure and moisture balance of the skin, properties that affect the skin’s ability to function as a barrier against chemicals. Earlier research has indicated that inherited variations of DNA sequences for filaggrin mean some people have less good
