Sunscreen<\/strong>, also known as sunblock<\/strong> or sun cream<\/strong>, is a photoprotective topical product for the skin that mainly absorbs, or to a much lesser extent reflects, some of the sun’s ultraviolet (UV) radiation and thus helps protect against sunburn and most importantly prevent skin cancer.<\/p>\n\n\n\n

Sunscreens come as lotions, sprays, gels, foams (such as an expanded foam lotion or whipped lotion), sticks, powders and other topical products. Sunscreens are common supplements to clothing, particularly sunglasses, sunhats and special sun protective clothing, and other forms of photoprotection (such as umbrellas). <\/p>\n\n\n\n

Sunscreen types<\/h2>\n\n\n\n

Sunscreens are classified into inorganic (mistakenly called ‘physical’) sunscreens (i.e., zinc oxide and titanium dioxide) and organic (also, mistakenly referred to as ‘chemical’) sunscreens.<\/p>\n\n\n\n

Despite popular belief, both types of sunscreens work mainly by absorption of UV light, not by reflecting or scattering it.<\/p>\n\n\n\n

Medical organizations such as the American Cancer Society recommend the use of sunscreen because it aids in the prevention of squamous cell carcinomas.The routine use of sunscreens may also reduce the risk of melanoma. However, many sunscreens do not block ultraviolet A (UVA) radiation, yet protection from UVA is important for the prevention of skin cancer.<\/p>\n\n\n\n

Research by the FDA on the safety of the main three organic UV filters (oxybenzone, homosalate and octocrylene) found that the three ingredients could be detected on the skin, in blood, in breast milk and in urine samples weeks after no longer being used.<\/p>\n\n\n\n

To provide a better indication of their ability to protect against skin cancer and other diseases associated with UVA radiation (such as phytophotodermatitis), the use of broad-spectrum sunscreens has been recommended.<\/p>\n\n\n\n

Why you should avoid sunscreen higher than SPF 50?<\/h2>\n\n\n\n

SPF (short for “sun protection factor”) is a measure of how well a sunscreen protects you from UVB. It seems like an SPF 100 sunscreen would give you double the protection of an SPF 50 sunscreen. But the truth is that higher-SPF products are only marginally better at shielding you from UVB, according to the Skin Cancer Foundation<\/a>. SPF 30 blocks nearly 97% of UVB radiation, SPF 50 blocks about 98%, and SPF 100 blocks about 99%. <\/p>\n\n\n\n

A higher SPF product might also encourage you to stay out in the sun longer. Moreover, researches indicate the higher SPF ,the more side effects due to complexity of ingredients. Instead, choose an SPF between 15 and 50, apply liberally, and reapply often.<\/p>\n\n\n\n
