Understanding Sunscreen: The Basics
Sunscreens, often referred to as sun creams, are formulated to protect the skin from the harmful effects of ultraviolet (UV) radiation. There are two types of UV rays that affect the skin: UVA and UVB. UVA rays penetrate the skin more deeply and are primarily responsible for premature aging and wrinkling, while UVB rays are the main cause of sunburn. Both types contribute to the risk of skin cancer.
Types of UV Radiation
Understanding UVA and UVB rays is essential for selecting the right sun protection. UVA rays are long-wave rays that penetrate deep into the dermis, the skin’s thickest layer. They are present with relatively equal intensity during all daylight hours throughout the year, and can penetrate clouds and glass. This makes protection against UVA critical, even on cloudy days or indoors.
UVB rays, on the other hand, are short-wave rays that are primarily responsible for direct damage to the DNA in skin cells and are the main cause of sunburn. They vary by season, location, and time of day, with the most significant amount reaching the Earth’s surface between 10 a.m. and 4 p.m. during the spring and summer months. Understanding this can help you plan outdoor activities at safer times of the day.
