Healthier Me: Take a "Shot" of Sunscreen

Posted: Updated:

Next time you head to the pool or the beach at the lake-- grab your sunscreen and your shot glass.

It's not for booze. The shooter is actually for your sunscreen. It's a way to eyeball just how much sunscreen you should be putting on.

A shot glass holds about an ounce to an ounce and a half and that's how much sunscreen an adult should be putting on before heading out in the sun.

Sanford Health Dermatologist Dr. Yulia Khan says one of the biggest problems with sunscreen is that people often don't use enough.

Dr. Khan says sunscreen needs to be applied in a thick layer and reapplied at least every 2 hours.  

Adults need to apply at least 1 ounce of sunscreen per application. That means most people will need to head back to the store to buy more.

Dr. Yulia Khan/Sanford Health Dermatologist: "A bottle of sunscreen is typically 8 ounces, so if you put an ounce on and reapply every few hours - that bottle will only last you a couple of days at most."

A thick layer of sunscreen feels "goopy" when you first put it on -- that's ok. It will take a few minutes to absorb into the skin.

If you are using a spray, doctors recommend you use one that is not clear. The light white coloring helps you see where you have sprayed. Like the cream, it will quickly absorb into your skin.

Here's a good reminder too. Sunscreen should be applied at least 15 minutes before going outside. There are two reasons for this: (1) Chemical sunscreens need several minutes to soak into the skin to give full protection. (2) It limits sun exposure before and during sunscreen application.
