Whether melanoma, basal cell carcinoma or squamous cell carcinoma, the best treatment plan is to prevent skin cancer from developing in the first place. This is achieved by limiting the damage caused by exposure to the sun.
Follow these helpful tips:
Avoid extended, direct exposure to the sun, especially between the peak hours of 10 a.m. and 4 p.m.
Avoid tanning beds and UV tanning booths. Never seek a tan. There is no such thing as a healthy tan – a tan is the skin’s response to the sun’s damaging rays.
Cover up with clothing, including a broad-brimmed hat and UV-blocking sunglasses. Those swim shirts (often with an ultraviolet protection factor of more than 50) are also a great idea, especially for children.
Use a broad spectrum (UVA/UVB) sunscreen with an SPF of 30 or higher every day. For extended outdoor activity, use a water-resistant, broad spectrum (UVA/UVB) sunscreen with an SPF of 30 or higher.
Apply one ounce (two tablespoons) of sunscreen to your entire body 30 minutes before going outside. Apply a generous amount. If you are unsure how much you need, apply twice as thick a layer of sunscreen as you think you should – studies have shown this is the only way to reach the SPF claimed on the bottle. If you burn easily, have blue eyes, red hair and/or freckles, take particular care to do this.
Reapply sunscreen every two hours or immediately after swimming or excessive sweating. Remember to apply sunscreen to the tops of your ears, tip of your nose, back of your hands and tops of your feet. And don’t forget your lips! Use a lip balm with at least an SPF of 30.
Keep newborns out of the sun. Their bodies cannot tolerate direct sunlight and heat. Find shade or cover up. At 6 months of age, baby sunscreens can be applied.
Avoid spray sunscreen as your sole form of sun protection. Although they are easier to apply, sprays fly away in the wind and are often not as effective with practical use. Unless one can be diligent about ensuring a generous layer of sheen uniformly distributed on the skin, sprays should only be used in conjunction with a lotion, which can achieve more uniform coverage.
Sunscreen does go bad. Most will last up to three years – a good trick is to write the purchase date on the bottle so you can keep track. Some sunscreens will have an expiration date printed on the label. If it’s past the date, throw it away. However, if you’re using it as often as you should, you’ll run out way before it goes bad.
When looking at sunscreens, you should be familiar with the two types of UV blockers.
Chemical Blockers. UV blockers are chemicals that absorb into the outer layer of the skin and absorb the UV light, preventing damage. These are conveniently packaged into gels, sprays and non-greasy lotions. Active ingredients to look for include oxybenzone and avobenzone (Parsol®). Other ingredients to look for are helioplex or mexoryl, which are highly recommended when this type of sunscreen is the sole form of UV protection.
Physical Blockers. UV blockers are “nanoparticles” (not chemicals) that physically coat the skin (instead of being absorbed) and reflect the UV light. These sunscreens contain the active ingredient zinc oxide or titanium dioxide. Though generally thicker and harder to rub in, these are considered the best defense against the sun’s harmful UV rays and are recommended for young children. “Baby” and “kids” sunscreens and “invisible zinc” are examples.
