A picture can speak a thousand words, and this video on what the sun does to your skin certainly achieves that.
If your in denial about the risks of UV and why your skin requires protection, this video puts it into perspective.
Thomas Leveritt uses an ultraviolet lens to capture sun damage in the skin, which is usually invisible to the naked eye.
Those who took part in the video look shocked when they see the damage UV does to their skin, which appears healthy in normal light.
He also does a really great job of showing just how effective sunscreen is when applied to the skin, which looks black in ultra violet light.
