Sunscreen: How to Select, Apply, and Use It Correctly

When To Apply Sunscreen

• Apply sunscreen at least two times a day. First application should be approximately 30 minutes before being in the sun so that it can be absorbed by the skin and less likely to wash off when you perspire. Second application should be around midday (12-1pm).
• Application of sunscreen is advisable even on cloudy days because although UVB radiation is minimal, UVA radiation (known to brake down collagen and cause skin cancer) is always present during daytime. Also most lamps irradiate small but continuos ammounts of UVA when lit.
• Remember to reapply sunscreen after swimming or strenuous exercise.
• Apply sunscreen often throughout the day if you work outdoors (every two hours), and wear hats (caps do not protect the ears and nape of neck area) and protective clothing (long sleeves shirts and long pants).

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.

What To Look for When You Buy Sunscreen

·         Pick a broad-spectrum sunscreen that protects against UV-A and UV-B rays.

·         Read product labels. Look for a waterproof brand if you will be sweating or swimming. Buy a nonstinging product or one specifically formulated for your face.
