I happen to think men believe that women spend way too much time on their skin/beauty regimens, which could be true (LOL).

What some men may not know is that by age 50 men are more likely than women to develop melanoma. And, that number continues to increase. (At age 65, men are 2 times more likely as women the same age to get Melanoma). At the age of 80 it is 3 times more likely. The research facts reveal Melanoma is harder on men.

I can actually confirm that none of the men I know use SPF.
If you are a man reading this post – do you? On a walk recently, I asked a neighbor, whom I see often, whether he had on SPF – he quickly admitted he did not. In addition, he did not have on a hat. This man is about 65-70 years old. I suggested he may want to consider using an SPF. He promised he would. As I said, The research shows that at his age he is 2 times more likely than a woman to develop melanoma. According to the AAD: 1 in 5 Americans will develop skin cancer in their lifetime.

In addition, Melanoma is more than 20 times more common in whites than in African Americans. Overall, the lifetime risk of getting melanoma is about 2.6% (1 in 38) for whites, 0.1% (1 in 1,000) for Blacks, and 0.6% (1 in 167) for Hispanics.

Although skin cancer is less prevalent in the black community than in the white population, when it does occur among people of color, it tends to be diagnosed at a later, and more advanced, stage.
