How to Take Care of Your Skin This Summer
Summer holidays are for family picnics, poolside fun, days at the beach and sunshine. But sunlight contains ultraviolet (UV) radiation, which consists of different types of rays that cause sunburn, skin damage, and can contribute to skin cancer.
Before you have your fun in the sun this summer, here’s what you need to know about taking care of your skin.
UVA vs UVB
UVA rays penetrate deep into the dermis, the skin’s thickest layer. Unprotected exposure to the sun can lead to premature aging and wrinkling (photoaging), and suppression of the immune system. UVB rays will usually burn the superficial layers of your skin and play a key role in the development of skin cancer.
What is SPF?
Sun Protection Factor (SPF) is a measure of how well a sunscreen will protect your skin from UVB rays. SPF is based on how long it takes for sunscreen treated skin to burn compared to skin with no sunscreen, e.g. an SPF 15 blocks 93% of UVB rays, SPF 30 blocks 97%, SPF 50 goes up to 98% and SPF 100 will protect you against 99% of UVA and UVB rays. It is important to note that no SPF offers 100% protection.
