While the natural aging process will occur and cause loss of collagen in our skin, UV damage will most certainly cause the skin to age more quickly. The sun and other UV sources such as tanning beds produce both UV-A and UV-B rays.
- UV-B rays are responsible for tanning/burning of the skin , and may lead to skin cancer.
- UV-B only penetrates the epidermis (very top layer of skin).
- UV-A deeply penetrates the skin in the dermis and causes the breakdown of collagen. Collagen is what gives our skin its support and youthful elasticity. UV-A induced breakdown is what can lead to wrinkly and leathery skin.
Some interesting facts about UV-A (Aging rays) to make you think twice about applying your sunscreen daily.
- UV-A is the same strength year round
- You don’t feel this UV ray as heat, and temperature does not dictate the amount of UV radiation being emitted.
- 99% of the UV radiation that reaches the Earth's surface is UV-A
- Up to 40 percent of the sun's UV radiation reaches the earth on a cloudy day.
- Car windows can block approximately 97% of UV-B rays, but UV-A rays are only blocked - out by 37%.
You are getting UV-A exposure anytime the sun is out. Any time of day, and any day of the year. UV-damage does not show up as sunburn, and will silently age your skin. While it is most important to get the first application on in the morning, it is also important to reapply if you know you will have longer periods of exposure. There are many choices for a great broad spectrum sunscreen that will protect against damaging UV-A and UV-B rays.
