This summer slow the signs of aging.
By Dr. Oscar Hevia
Nothing accelerates the aging process like ultraviolet rays – also known as THE SUN! This summer slow down the signs of aging and avoid the risks of skin cancer with the daily use of sunscreen. Here is a little shared wisdom about sunscreen to prepare for the summer months ahead.
Chemical Sunscreens vs. Physical Sunscreens
Chemical sunscreens contain substances, such as “oxybenzone” or “octocrylene”, that absorb ultraviolet rays, while physical sunscreens that reflect or scatter ultraviolet rays, usually contain zinc oxide or titanium oxide. Physical sunscreens are considered safer since they lack certain chemical ingredients that may be of concern to some people.
The best sunscreens are labeled “broad spectrum”, which means they protect from both the burning rays (UVB), and the tanning rays (UVA). Both chemical and physical sunscreens can achieve this!
How often should they be applied?
This depends on the setting. For recreational activities, the sunscreen should be applied at least twice during the day, even more if you are bathing. Daily wear sunscreens can be applied once in the morning, provided your occupation does not require you to be outdoors regularly.
As always, please remember…
The most effective prevention measure is to avoid sun exposure. No matter how much we try to repair/protect our skin, it’s much better not to damage it in the first place! Although sunscreens can be quite sophisticated these days, they are never good enough to protect from the damaging rays. ■
