With the days getting longer and the temperatures getting warmer, we can expect to find ourselves outside more often. But as you reach for the sunscreen you purchased last year, is it still effective in protecting your skin from sun damage?  Maybe.  Sunscreen does expire and is effective for three years after being produced.  However it may be a hard date to determine as not all containers carry a date. Plus where you stored your sunscreen matters.  Extreme temperature and humidity fluctuations can shorten its lifespan too.  So a bottle of sunscreen stored in the glovebox of your car may only be effective for a few months compared to bottles stored at room temperature. The best advice is that if you are in doubt, toss it out.  Also, if the sunscreen ingredients have separated, looks watery or has a funny smell, toss it out and purchase a new tube.
