Daily use of a good sunscreen will fend off sunburns today, and help prevent the damage that leads to prematurely aged skin later on in life.

Growing up in Southern California, summertime meant heading to the beach or swimming pool, a bottle of what was then labeled “tanning oil” in hand. SPF wasn’t a thing back then. In fact, I often slathered mineral oil on my skin to increase the tanning effects. Of course, I paid a price for that youthful foolishness with sunburns back then, and today, in freckled patches of sun damage along with a greatly increased risk of skin cancer.

Here are a few more important facts (although, for the full rundown, you should check out The American Cancer Society’s website):
These rays are connected to the “broad spectrum protection” you see on sunscreens.
While UVA rays are less intense than UVB rays, they penetrate your skin more deeply. Basically, exposure to UVA rays can cause genetic damage to cells in the top layer of your skin, where most skin …read more
