Polymorphous Light Eruption Polymorphous light eruption, or PLE, is the most common skin disease caused by sunlight. It is also called polymorphic light eruption (PMLE). Other variants include juvenile spring eruption and benign summer light eruption. PLE is not the same as sunburn, but may appear as something like a sunburn rash. PLE arises spontaneously in people who are sensitive to ultraviolet light and is characterized as one type of photodermatosis. It usually manifests as an itchy rash—little red bumps or slightly raised patches of skin—after sun exposure in people who are photosensitive. While the rash can take different forms...

Sun exposure is responsible for most of the visible aging of your skin—far more than all other factors combined. Yes, UV rays from the sun are the primary cause of wrinkles, pigmentation, sun spots, reduced skin elasticity, the degradation of skin texture, and many other signs of skin aging. In fact, many scientific estimates have shown that up to 80-90% of how young or old you look for your age is due to how much sun exposure you’ve sustained. And this has been shown repeatedly, in different parts of the world, over many years and in many different clinical studies....

There’s a lot of confusion surrounding sunlight and the production of Vitamin D. People commonly think that if the sun is up and they are outside in the sun, they are going to produce Vitamin D. This is not the case! There are many reasons why you won’t make Vitamin D in the sun—even during the middle of the day. But most significantly, the sun cannot stimulate your production of Vitamin D if the sun isn’t high enough in the sky. UVB Rays And Vitamin D The reason is that UVB rays—and only UVB rays—catalyze the production of Vitamin D....

It’s true. The average vegetable or fruit produced today has significantly less vitamins and minerals than the varieties that were grown decades ago. And this decline in nutrients has been taking place for at least 50 or 60 years. How Much Have The Nutrients In Fruits And Vegetables Decreased? The landmark study on this topic was published in 2004 by Donald Davis. Entitled Changes in USDA food composition data for 43 garden crops, 1950 to 1999, the paper details the results of the measurements of 43 garden crops for 13 nutrients and how the data changed between 1950 and 1999....

What Is Grape Seed Extract? Grapes have been cultivated and eaten for a long time. But grapes, along with other parts of the Vitis vinifera plant such as the leaves and sap, have also been used in traditional medicine in Europe for thousands of years. From the Egyptians to the ancient Greeks, the healing power of grapes and wine were realized, and grapes and grapevines were used to treat a variety of conditions including inflammation, pain, constipation, infections, and even various diseases. Today, grape seed extract is made primarily from the seeds of wine grapes. Grape seed extract has a...
