SPF IS YOUR BEST FRIEND
Clinical signs of aging are mostly influenced by external factors, specifically sun exposure and photoaging causes 90% of visible skin changes.
We all age and there is nothing we can do to physically slow down the clock. The most effective thing you can do to prevent early signs of aging, and importantly skin cancer is to wear sunscreen.
When purchasing a sunscreen make sure it says broad spectrum on the label. This means it offers protection from both UVA and UVB rays (or recently even UVC) , with at least 30 SPF or higher. I always use SPF 50.
According to the Skin Cancer Foundation, daily sunscreen use can decrease your chances of developing squamous cell carcinoma by approximately 40% and melanoma by 50%.
