If you\u2019re swimming or sweating a lot, you\u2019ll need to reapply more often.<\/p>\n<p data-journey-content=\"true\" data-node-id=\"9\" class=\"css-1ood0zq emevuu60\">And don\u2019t be afraid to be liberal with your application. Most people don\u2019t apply enough sunblock in the first application, so they aren\u2019t getting the same level of protection as stated on the label, explains <a href=\"https:\/\/lesliebaumannmd.com\/#home\" target=\"_blank\" data-vars-ga-outbound-link=\"https:\/\/lesliebaumannmd.com\/#home\" data-vars-ga-ux-element=\"Hyperlink\" data-vars-ga-call-to-action=\"Leslie Baumann, M.D.\" data-node-id=\"9.1\" class=\"body-link css-hllz2d emevuu60\" rel=\"nofollow noopener\">Leslie Baumann, M.D.<\/a>, a board-certified dermatologist, researcher, and founder of <a rel=\"nofollow noopener\" href=\"https:\/\/derm.net\/\" target=\"_blank\" data-vars-ga-outbound-link=\"https:\/\/derm.net\/\" data-vars-ga-ux-element=\"Hyperlink\" data-vars-ga-call-to-action=\"Baumann Cosmetic Dermatology\" data-node-id=\"9.3\" class=\"body-link css-hllz2d emevuu60\">Baumann Cosmetic Dermatology<\/a>. \u201cThis makes the sunscreen less effective, causing it to lose its ability to protect the skin,\u201d she notes.<\/p>\n<p data-journey-content=\"true\" data-node-id=\"10\" class=\"css-1ood0zq emevuu60\">Think you can skip sunscreen when it\u2019s cold or cloudy outside? Not so fast. Ultraviolet light, including UVB rays that damage your skin, may be less present on a cloudy day, but UVA rays are just as strong and cause more skin damage, per Dr. Baumann. In other words, you still need to wear sunscreen on rainy days and even during cold weather activities like skiing.<\/p>\n<p><strong data-node-id=\"11.0\">Should you ever reapply sunscreen more often? <\/strong><\/p>\n<p data-journey-content=\"true\" data-node-id=\"12\" class=\"css-1ood0zq emevuu60\">As a general rule, reapplying sunscreen every two hours will protect you from the sun\u2019s harmful rays. But there are a few situations where you may want to reapply more often:<\/p>\n<ul data-node-id=\"13\" class=\"css-12c7ta7 emevuu60\">\n<li aria-level=\"1\" style=\"list-style-type:disc;\" data-node-id=\"13.0\"><strong data-node-id=\"13.0.0\">When you\u2019re driving. <\/strong>\u201cPeople underestimate how much sun exposure they get when they\u2019re in the car,\u201d Dr. Woolery-Lloyd says. Whether you\u2019re the driver or a passenger, there\u2019s a good chance you\u2019re in direct sunlight, so you definitely want to abide by the two-hour reapplication rule. Dr. Woolery-Lloyd says she tells her patients to be extra cautious during long commutes.<\/li>\n<li aria-level=\"1\" style=\"list-style-type:disc;\" data-node-id=\"13.1\"><strong data-node-id=\"13.1.0\">When you\u2019re swimming. <\/strong>Water-resistant sunscreens are great, but they still need to be reapplied every two hours. You should also reapply sunscreen every time you dry off with a towel. When you wipe away the water, you\u2019re also wiping off your sunscreen.<\/li>\n<li aria-level=\"1\" style=\"list-style-type:disc;\" data-node-id=\"13.2\"><strong data-node-id=\"13.2.0\">When you\u2019re sitting next to a window. <\/strong>You\u2019re not safe from the sun\u2019s rays just because you\u2019re indoors; windows actually make it easy for the sun&#8217;s rays to get to you, whether they\u2019re open or closed. \u201cIf your office has a window, you can bet that you\u2019re actually getting quite a bit of sun,\u201d Dr. Woolery-Lloyd notes. So if you\u2019re sitting by a window for an extended period of time, follow the sunscreen rule and re-up every two hours (or more).<\/li>\n<\/ul>\n<p><strong data-node-id=\"14.0\">How does sunscreen work?<\/strong><\/p>\n<p data-journey-content=\"true\" data-node-id=\"15\" class=\"css-1ood0zq emevuu60\">There are two types of sunscreen: those with <a href=\"https:\/\/www.prevention.com\/beauty\/skin-care\/a31487742\/physical-vs-chemical-sunscreen\/\" target=\"_self\" data-vars-ga-outbound-link=\"https:\/\/www.prevention.com\/beauty\/skin-care\/a31487742\/physical-vs-chemical-sunscreen\/\" data-vars-ga-ux-element=\"Hyperlink\" data-vars-ga-call-to-action=\"physical or chemical blockers\" data-node-id=\"15.1\" class=\"body-link css-hllz2d emevuu60\" rel=\"nofollow noopener\">physical or chemical blockers<\/a>. Physical (or mineral) sunscreens contain ingredients like zinc oxide or titanium dioxide that sit on the skin, physically preventing UV rays from penetrating it. Chemical sunscreens have ingredients such as avobenzone and octisalate, which absorb UV rays before they can harm your skin. Physical sunscreens tend to be better for <a href=\"https:\/\/www.prevention.com\/beauty\/skin-care\/g35218769\/best-sunscreen-for-sensitive-skin\/\" target=\"_self\" data-vars-ga-outbound-link=\"https:\/\/www.prevention.com\/beauty\/skin-care\/g35218769\/best-sunscreen-for-sensitive-skin\/\" data-vars-ga-ux-element=\"Hyperlink\" data-vars-ga-call-to-action=\"sunscreens for sensitive skin\" data-node-id=\"15.3\" class=\"body-link css-hllz2d emevuu60\" rel=\"nofollow noopener\">sunscreens for sensitive skin<\/a>, but both types are safe and effective, according to the <a href=\"https:\/\/www.skincancer.org\/skin-cancer-prevention\/sun-protection\/sunscreen\/\" target=\"_blank\" data-vars-ga-outbound-link=\"https:\/\/www.skincancer.org\/skin-cancer-prevention\/sun-protection\/sunscreen\/\" data-vars-ga-ux-element=\"Hyperlink\" data-vars-ga-call-to-action=\"Skin Cancer Foundation\" data-node-id=\"15.5\" class=\"body-link css-hllz2d emevuu60\" rel=\"nofollow noopener\">Skin Cancer Foundation<\/a>.<\/p>\n<p data-journey-content=\"true\" data-node-id=\"16\" class=\"css-1ood0zq emevuu60\">To understand how sunscreen works (no matter which type you choose), think of it like a cup that gets filled by the sun\u2019s rays, Dr. Woolery-Lloyd explains. After a few hours, the cup gets full and can\u2019t absorb any more rays, so they go into your skin instead. \u201cReapplying sunscreen is like putting out a fresh cup to absorb the sun\u2019s rays, rather than letting it get into your skin,\u201d Dr. Woolery-Lloyd explains.<\/p>\n<p><strong data-node-id=\"17.0\">Tips for remembering to reapply sunscreen<\/strong><\/p>\n<p data-journey-content=\"true\" data-node-id=\"18\" class=\"css-1ood0zq emevuu60\">It\u2019s easy to forget to reapply your sunscreen, but there are things you can do to help you remember. To get into a daily habit, try adding it to your regular routine. \u201cApply sunscreen in the morning after you brush your teeth, then apply it again before you go to lunch or anytime you are headed outside,\u201d Dr. Baumann suggests. Don\u2019t forget areas like your ears, neck (front and back), chest, and the top of your hands.<\/p>\n<p data-journey-content=\"true\" data-node-id=\"19\" class=\"css-1ood0zq emevuu60\">Above all, find a sunscreen you love, <a href=\"https:\/\/www.prevention.com\/beauty\/skin-care\/g71204115\/best-sunscreen-for-face\/\" target=\"_self\" data-vars-ga-outbound-link=\"https:\/\/www.prevention.com\/beauty\/skin-care\/g71204115\/best-sunscreen-for-face\/\" data-vars-ga-ux-element=\"Hyperlink\" data-vars-ga-call-to-action=\"especially for your face\" data-node-id=\"19.1\" class=\"body-link css-hllz2d emevuu60\" rel=\"nofollow noopener\">especially for your face<\/a> (since reapplying here can be a bit tricky).
