Whether you’re driving, at home gazing out at your garden, or sitting by a window at work, you actually may be suffering continual skin damage.

UVA penetrates deep into the skin, causing DNA damage that can accelerate skin aging and lead to skin cancer.If you frequently sit by windows, the single best safeguard against UV damage is transparent window film,sometimes referred to as window tint, which has been specially treated to screen out both UVA and UVB rays. Installing protective film on your windows will keep you virtually UV-free on the road, at home, or at the office.
