3- Not Wearing Sunscreen
Regularly wearing sunscreen won’t just protect you from potentially deadly skin cancer; it’ll keep you looking younger as well. Over time, UV light exposure can damage the skin, causing long-term changes like photoaging, or premature aging of the skin because of sun exposure, says Harvard Medical School. Photoaging causes changes in collagen deep down within the skin, leading to the formation of wrinkles and fine lines. To avoid it, experts advise consistently wearing a sunscreen of at least 30 SPF, with a broad spectrum of protection against both UVA and UVB rays.
