Sunscreen 101: Understanding SPF, UVA, and UVB Protection
In order to maintain healthy and glowing skin, one must protect the skin from the sun’s damaging rays. Sunscreen is a crucial component of a daily skincare routine, and it is essential to understand the basics of sunscreen to ensure optimal protection.
SPF, UVA, and UVB are the three most common terms that you will come across when shopping for sunscreen.
Sun Protection Factor which is commonly known as SPF shield your skin from UVB rays. The higher the SPF value, the more protection it offers against UVB rays. However, it is important to note that SPF does not measure protection against UVA rays, which can penetrate deeper into the skin and cause premature aging, wrinkles, and skin cancer.
UVA rays are responsible for the aging effects of the sun on the skin. They are present throughout the day and can also penetrate through clouds and windows. Because UVA rays are not filtered by glass, it is necessary to wear sunscreen even when indoors. UVA protection is measured by the PA rating (Protection Grade of UVA), which ranges from PA+ to PA++++. The greater the number of plus signs, the greater the level of protection. UVB rays are the primary cause of sunburn and also the reason of skin cancer. They are strongest between 10 am to 4 pm and are responsible for most of the skin damage caused by the sun.
UVB protection is measured by the SPF value, which ranges from 15 to 100+. When you wear sunscreen with an SPF of 30, your skin will burn 30 times more slowly than it would if you did not. When choosing a sunscreen, it is important to look for a broad-spectrum sunscreen that protects against both UVA and UVB rays. It should also have an SPF of at least 30 and be water-resistant if you plan to swim or sweat.
It is recommended to apply sunscreen 15 minutes before going outside and reapply every two hours or after swimming or sweating. In conclusion, understanding SPF, UVA, and UVB protection is essential for choosing the right sunscreen for optimal protection against the sun’s harmful rays. Remember to always wear sunscreen, even on cloudy days, and reapply every two hours for maximum protection. Taking care of your skin today can prevent premature aging and help reduce the risk of skin cancer.
