Somewhere in the ballpark of 10 million Americans suffer from Seasonal Affective Disorder (S.A.D.), also commonly called winter blues. Those who experience S.A.D. are. . . well. . . sad. And you can paint the sadness on a spectrum — from mild malaise to severe depression. For those who live north of a virtual line going from DC to San Jose, winter blues is a real thing.
The ultraviolet sun ray UVA1 causes skin damage and is responsible for kickstarting the photoaging, or premature aging, process. The University of Michigan Department in Dermatology conducted a study and found that even in low levels, UVA1 ultimately leads to saggy and wrinkled skin. It is yet undetermined whether or not UVA1 exposure is linked to skin cancer. Finally, most sunscreens sold on the market do not protect against UVA1.
Our daily passive exposure to sunlight year-round – even on seemingly sunless and chilly days, combined with the blue light radiations coming from our electronic devices, is where most of our photoaging - the premature aging of our skin due to sunlight and UV radiation - is happening.
With the summer in full swing, you might be carrying that sunscreen as if it were a bottle of fresh water in the middle of the Death Valley.

Wearing sunscreen at all time is actually a mistake and under a few specific conditions, you should give your skin a break from SPF of all kinds, even the mineral ones.
