Not too long ago I shared a picture of my own patient who looked years younger once her skin tone was evened out compared to eight years prior when she was eight years younger and her skin tone was all sorts of places because of sundown. So what can you do to help yourself? The damage is usually done before you're 20, but it does get worse if you keep laying out in the sun. So number one, sunscreen obviously. Sunscreen. Just wear the damn sunscreen already and stop being scared of it. Number 2a. Avoid the sun at peak hours. Usually peak hours are on average anywhere from 10am to like 4pm depending where you are on planet Earth and the equator, but that's a good rule of thumb. And number three, invest in UV protective clothing, clothing with UPF or hats with UV protection, I. E. Visors that actually protect against UV rays that can worsen your sun damage and risk for skin cancer.
