It is those daily drops of UV exposure that you might not see today or tomorrow but years from now it will show up in the form of wrinkles, age spots and hyper pigmentation.
Your daily exercise and errands should not contribute to pre-mature aging. It is the daily drops of UV Rays as you are outside exercising, on a walk, hiking and driving in your car that are aging you faster than necessary. Even though you might use SPF your skin it is still exposed to the UVA Rays which represent 95% of the Sun's Rays and are the main contributor to skin aging. By covering up with eclisse you are adding another layer of protection.
This commitment to covering up and protecting yourself from the daily drops will make a world of difference to the aging of your skin. You can keep your skin looking decades younger than your actual age.
