Broad Spectrum ProtectionThe main purpose of sunscreen is to keep the sun’s ultraviolet radiation from reaching the skin—sunscreen achieves this by blocking and deflecting UVA and UVB rays from the skin’s surface. Both damaging, UVB rays are primarily responsible for sunburns, while UVA rays damage DNA by penetrating deep into the skins underlying layers. Know this: UVA rays exacerbate the carcinogenic effects of UVB rays. Thus, it’s important to find a broad spectrum sunscreen that protects against both UVA and UVB rays.
All Day, Every DayWith so many options available to you, it can be difficult to know which sunscreen will work best for you. Unless you spend the majority of your time outdoors, SPF 30 is sufficient for daily use. We encourage our patients to seek out skin care and beauty products that incorporate SPF protection. Women, seek out makeup with built in SPF protection—moisturizers, foundations, and even certain powders can provide protection. Men, in addition to a daily moisturizer, many aftershaves now include SPF protection.
