Skin ages both externally and internally. The number one cause of external aging is sun exposure. Ultraviolet rays in sunlight cause damage at the cellular level. This leads to wrinkles as well as skin cancer. In addition, external aging is caused by exposure to environmental factors such as pollution. This is called oxidative damage. Internal aging is a genetic process. This occurs when the two key structural components of skin, collagen and elastin, diminish over time. Internal aging causes the skin to lose elasticity and firmness. This eventually results in sagging, dullness, and wrinkles.

How do I prevent internal and external aging?! While you can’t stop internal aging, there are ingredients that help postpone the process. There are also many ingredients that prevent the external aging process. These anti-aging ingredients are found in each and every Likewise moisturizer as well as our full line of anti-aging products.

A key element in anti-aging and UV protection is vitamin D. It’s a well-documented fact that when ultraviolet (UV) rays from sunlight strike your skin, they can trigger vitamin D production. It’s also a well-known fact that UV rays are the number one cause of skin cancer. This reason alone should be enough to convince you to seek your vitamin D elsewhere!

If you’re curious about how to get the vitamin D the right way, consider the following:

  • Get your vitamin D from supplements and food such as fish, fish liver oil, eggs, milk, cheese, yogurt, fortified soy milk or orange juice, and certain cereals and breads.
  • Get the right amount of vitamin D. You should check with the Food and Nutrition Board and consult your primary care physician for the recommended dose of vitamin D – high doses can be unsafe.

A new skin study published by the Annals of Internal Medicine confirms what doctors have long preached. Daily, year-round sunscreen use can significantly slow the skin's aging process by as much as 24 percent (June 3, 2013):
