The Signs of Photo-Aging: How to Prevent Irreversible Sun Damage
It is estimated that 1 in 5 Americans will develop skin cancer in

Effect UVB and UVA Rays Have on Your Skin
As new research comes out, the kinds of damage each UV ray causes
changes. Even though Vitamin D is provided by the sun, and is extremely
important to us in supporting the health of our bones, muscles, skin, eyesight,
heart and immune system, we still need to take necessary precautions not to
abuse our time in the sun.
UVB rays are chiefly responsible for giving you a sunburn. UVB rays are
strongest from April-October between the times of 10am and 4pm. UVA rays are
around equally during all times and seasons, cause tanning and will also be
responsible for most of your skin aging as they penetrate skin more deeply. UVA
rays, unlike UVB rays, can penetrate windows and even lightweight clothing -
even on a cloudy day. Both can cause cancer and premature aging because of the
damage being done to the skin cells and their DNA.
It is also important to note that getting tan causes irreversible
damage to your skin, which you will see as you age.
Moderation in sun exposure and using proper sun protection are
your keys to safety since long-term, excessive exposure to sunlight can
increase the risk of certain types of skin cancer.
