If your sunscreen expiration date was sometime during the Reagan administration, it might be time to replace it. Honestly, if you’re using it that infrequent, you’re leaving yourself exposed. The quality and efficacy of any product diminishes beyond its expiration date. For sunscreen, this is a big deal. You may be, unknowingly, over-exposing your skin to the sun’s ultraviolet rays that most often leads to premature skin aging and skin cancer. Open your cabinet and look at the date. Do you notice that odd color? What about the lumpy gunk or runny slime coming from the bottle? Throw it away and get a medical grade sunscreen. At Paladin Dermatology, we carry ELTA MD Daily or ELTA MD Clear for daily use on your face and the Elta Spray for the rest of your body. Apply a blueberry-sized drop of sunscreen to your face every morning after cleansing/shaving, and don’t forget about your ears. These sunscreens have a moisturizing base, so don’t feel like you need two different products. If you’re going out in the sun, apply your sunscreen 20 minutes beforehand, and reapply every 1-2 hours.
