Factors in Skin Aging.
What causes these signs of aging, and what can we do to prevent them? As Dr. Björn Örvar, cofounder and CSO of BIOEFFECT points out, “There are many factors that affect our skin and how fast the skin ages.” Though genes play a role in that process, how much of a role has yet to be determined. It’s also been scientifically proven that the skin is affected by diet as well as smoking. But as Dr. Örvar also points out, “We know the environment is usually not nice to our skin.” In fact, air pollution is highly detrimental to it. A recent study in theJournal of Investigative Dermatology, “Airborne Particle Exposure and Extrinsic Skin Aging” (December 2010), assessed the influence of air pollution on skin aging in 400 women. It found that “Air pollution exposure was significantly correlated to extrinsic skin aging signs.” In fact, one of the most astounding findings in the study was the fact that dark spots may not be exclusively linked to sun exposure, as was previously thought, but to oxidative stress.
