By Shot Glass or Coins
Another way to apply sunscreen on your whole body in a well-proportioned manner and measured quantity is by using a shot glass. When it comes time to apply to the face, you won’t need as much, a whole shot glass would be too much. For your face, Ilyas says you’ll use enough sunscreen to fill the bottom of your shot glass.
You can also use a nickel to measure up the quantity of sunscreen to use on your face. Put your loose change to good use. Put a nickel-size dollop on your face.
