SPF is actually important no matter what your skintone is! The sunlight that reaches us is made up of two types of harmful rays: long wave ultraviolet A (UVA) and short wave ultraviolet B (UVB). UVA rays penetrate deep into the dermis, the skin’s thickest layer. Unprotected exposure can lead to premature skin ageing and wrinkling (photoaging), and suppression of the immune system. While UVA rays don’t cause sunburn, they do penetrate the skin more deeply than UVB rays and can lead to darkening, wrinkles and an increased risk of skin cancer.

UVB rays will usually burn the superficial layers of your skin. It plays a key role in the development of skin cancer. The intensity of UVB rays vary by season, location and time of day, with 10AM to 4PM being the peak hours. Sunburned skin doesn’t just feel awful, it can cause permanent damage over time. So, regardless of your skin tone, it is super important to protect your skin!
