Spring is almost on us and it is time to get organized for yard work. One thing to keep in mind as we brave the new season is sunscreen. According to the Mayo Clinic, most sunscreen works at full strength for about three years. So, if you are not sure how old those tubes and sprays are, toss them and replenish.
Incidentally, an SPF 15 product blocks about 94% of UVB rays; an SPF 30 product blocks 97% of UVB rays; and an SPF 45 product blocks about 98% of rays. Most experts tell us to save our money and do not pay for SPF above 30.
