Sunscreen is key to protecting your skin against the sun\u2019s harmful rays that can cause skin cancer. But which kind should you use and how often should you apply it? And is there a difference between SPF 15, 50 and 100? Newsday<\/strong> asked local dermatologists to help sort it out.<\/p>\n\n\n\n

Why is it important to wear sunscreen?<\/h3>\n\n\n\n

Ultraviolet (UV) radiation from the sun causes the formation of free radicals that can damage skin at the cellular or DNA level, said Dr. Navin Arora<\/a><\/span><\/strong>, a dermatologist and medical director of Borealis Dermatology in Garden City and Syosset. UV exposure can cause early signs of aging such as wrinkles and sun spots, as well as skin cancer. Sunblock can prevent the effects of chronic UV exposure, he said.<\/p>\n\n\n\n

What are the different types of sunscreen?<\/h3>\n\n\n\n

There is physical sunscreen and chemical sunscreen, explained Dr. Raman Madan, director of cosmetic dermatology at Northwell Health, who sees patients in Huntington and New Hyde Park. \u201cPhysical sunscreen has titanium dioxide or zinc oxide in it and that protects you by physically blocking the sun from touching your skin,\u201d he said. \u201cChemical sun-screen goes into your skin and prevents any UV damage when the sun hits your skin.\u201d<\/p>\n\n\n\n

How often should you apply and reapply sunscreen?<\/h3>\n\n\n\n

You should apply it at least every two hours and even more when you are swimming and going into the water, Madan said<\/p>\n\n\n\n

Arora<\/a><\/span><\/strong> suggests putting on sunscreen at home, before you get to the beach or the pool, to give it time to absorb before your sun exposure. \u201cPeople think \u2018Oh, I\u2019m at the beach. Let me put it on now\u2019 but you have this 30-to 45-minute window where it hasn\u2019t fully absorbed and now you are really susceptible.\u201d<\/p>\n\n\n\n

What SPF sunscreen should you use? Is a higher SPF better to use?<\/h3>\n\n\n\n

SPF 30 and above is fine, Madan said. \u201cSPF 30 protects you from 97% of the sun, SPF 50 is 98% and SPF 100 is close to 99%,\u201d he said. \u201cI\u2019m OK with people using the SPF 30 be-cause it\u2019s still giving you a lot of protection and usually it goes on a little bit lighter than SPF 100.\u201d<\/p>\n\n\n\n

\u201cIt\u2019s really how much do you apply, how often do you apply,\u201d Arora<\/a><\/span><\/strong> said. \u201cThose are the more important characteristics of the sunblock rather than sometimes the numbers beyond 30 SPF or 50 SPF.\u201d<\/p>\n\n\n\n

What else can I do to protect myself from the sun?<\/h3>\n\n\n\n

\u201cAvoid peak hours, the sun is strongest between 10 a.m. and 2 p.m.,\u201d Madan said. \u201cThere is clothing with SPF built into it, which I use with my kids. And wear a hat and sunglasses. All those things make a big, big difference.\u201d<\/p>\n\n\n\n
