Do I need to reapply my sunscreen at the end of the day at my office?
You’re welcome!! Sunscreens do degrade on the skin over time slowly with exposure to light, blotting or wiping the skin, exposure to our natural skin oils, etc. I’ve never seen a study on how fast they degrade in an office environment. The real question is what are you doing when you leave the office? If you are in the car for awhile, walking outside, going for a run, etc., I would recommend reapplying the sunscreen before you leave the office. Dr. I
