How vitamin A was found to be a Vitamin Vitamins are organic compounds that are essential to human metabolism, but that humans are unable to synthesize so they must be acquired through food. During evolution, we “simply” lost some enzymes required for their synthesis. Observations made before 1900: Nutritional deprivation caused corneal ulcers, blindness, and high mortality. Also, an unknown substance present in milk and egg yolk is essential for nutrition. In the early 20th century it was found that this unknown substance was fat soluble. The growth-supporting “accessory factor” in milk and egg yolk became known as ‘fat-soluble A’ in 1918 and then ‘vitamin A’ in 1920. Further research,…

In my opinion, mitochondria, antioxidants, and protection from UV are the keys to keeping skin healthy for the many years our skin has to do its job. In other words, the need to protect skin from UV and strong oxidants, and to protect the integrity of mitochondria is NOT age specific. It is not practical to have several mitochondria creams to target different ages. It is easier to formulate the best possible mitochondria cream (Revitalizing Night Cream) and “layer” products to complement its action. For example, a woman of 50 may wish to layer Anti-Aging Cream on top of Revitalizing Night Cream and/or Collagen Serum. Let me explain why mitochondria…

Collagen fibers give the skin resistance to strain and traction. Collagen constitutes about 70% of skin mass, but total collagen decreases about 1% per year. It may look like a small decline, but as such a major component of the skin it will affect skin volume and its physical properties. Also, aging changes collagen structure. What was an organized pattern in young skin, becomes an assembly of disorganized bundles of thick fibrils in older skin. It is not only quantity, it is also quality. We know that aging decreases skin thickness and elasticity, and it is likely that collagen is a good part of the solution. If we care about…

The New York Times posted an article last month with this headline: ‘Second Skin’ May Reduce Wrinkles, Eyebags, Scientists Say. If you continue reading, you will find that title to be slightly misleading. Let’s break down what the article actually states. A silicone solution is applied to your skin and becomes a mesh that stretches and covers your skin with a transparent film that will last for up to 24 hours. It will not reduce wrinkles, just hide them underneath the transparent mask. You can’t criticize a scientist for trying to make money. We don’t pledge a Hippocratic-type oath that forbids us from benefitting financially from our breakthroughs. It would definitely not be the first time that somebody with a PhD…
