I’m not saying you should fire your aesthetician, but good skin health unquestionably comes from within, not from without. Skin is merely the reflection of good health. We know that smokers’ skin is very prone to wrinkles, and most think this is from the smoke directly off the tip of the cigarette. It could just as easily be from the internal destruction of health over time.
Also consider the public health issue of avoiding sun to protect from skin cancer. This sounds great, until you combine the fact that this is leading to a rash of Vitamin D deficiency with its long list of detrimental effects and the fact that the most common areas of melanoma are the back (in males) and lower legs (women)–NOT areas with the most sun exposure.
This means that other factors are likely playing the larger role in our increase in melanoma rates. The heavy deficiencies of protective phytochemicals in our processed diets offer nothing to protect our skin from UV-induced damage. This study supports this concept, finding that an extract from green tea protects the skin from UV-induced damage and improves overall appearance.
This does NOT mean that we all start taking green tea supplements. What this means is that tea (not just green, but black and white as well) should be the primarily drink we take in to achieve the greatest long term protection.
