The sunlight that reaches us comprises two harmful rays: long wave ultraviolet A (UVA) and short wave ultraviolet B (UVB). Simply put, UVA causes Aging, and UVB causes Burn.
UVA rays penetrate deep into the dermis, the skin’s thickest layer. Unprotected exposure can lead to premature skin aging and wrinkling (photoaging) and suppression of the immune system.
UVB rays will usually burn the superficial layers of your skin. It plays a crucial role in the development of skin cancer. The intensity of UVB rays varies by season, location, and time of day, with 10 AM to 4 PM being the peak hours. Sunburned skin doesn’t just feel awful; it can cause permanent damage over time.
