When To Apply Sunscreen
Apply sunscreen approximately 30 minutes before being in the sun (for best results) so that it can be absorbed by the skin and less likely to wash off when you perspire.
Remember to reapply sunscreen after swimming or strenuous exercise.
Apply sunscreen often throughout the day if you work outdoors, and wear hats and protective clothing.
How To Apply Sunscreen
Shake well before use to mix particles that might be clumped up in the container. Consider using the new spray-on or stick types of sunscreen.
Be sure to apply enough sunscreen. As a rule of thumb, use an ounce (a handful) to cover your entire body.
Use on all parts of your skin exposed to the sun, including the ears, back, shoulders, and the back of the knees and legs.
Apply thickly and thoroughly.
Be careful when applying sunscreen around the eyes.
