Vitamin A for Skin Health

This is the first in a series of topics discussing Vitamins for your skin health. Later topics will include botanical ingredients as well as natural compounds such as DMAE, MSM and CoQ10.

Let's go alphabetical starting with A, Vitamin A that is! It's common knowledge that Vitamin A is good for the skin. Many have found relief from acne by applying serums, lotions and cremes containing Vitamin A. There are two common forms found in consumer products. The most potent form of Vitamin A is called Retinol (Retinol Palmitate). This form is found in meat products and vitamin supplements. In higher concentrations Retinol can be quite toxic. The vegetable form of Vitamin A is beta-carotene and is a non-toxic precusror of Vitamin A (sometimes called pro-Vitamin A) that is converted in the body into retinol and stored in the liver.

Before we get into the nitty-gritty let's summarize what collagen is. Think of it as the glue (it's actually a protein) that holds all kinds of body tissue together. It helps to provide the skin with strength, flexibility, and resilience. As people age collagen degradation occurs, leading to wrinkles. Drum roll please...Vitamin A increases collagen absorption for the skin. Wooo hoooo!!!

OK, bear with me on the science stuff for a moment. There's been some debate as to which type of Vitamin A is best. Retinol Palmitate nourishes the skin and assists in the rejuvenation process that maintains a more youthful appearance. But what about beta-carotene? According to research, "topical beta-carotene has been shown to penetrate well into the epidermis and induced a 10-fold increase of epidermal retinyl esters, which demonstrates that topical beta-carotene is converted into retinyl esters by the epidermis and becomes a precursor of epidermal vitamin A."*  Retinyl ester is what Retinol becomes after being fully broken down. Simply put, beta-carotene (the mildest form of Vitamin A) works great in lotions, serums and cremes to increase collagen absorption!

Vitamin A is also a powerful antioxidant because it traps free radicals. Free radicals are a byproduct of normal cell function, pollution, and UV radiation from the sun. The free radical bonds to other molecules causing proteins (remember, collagen is a protein) and other essential molecules to not function as they should. This asserts that many of the changes that occur as our bodies age are caused by free radicals.  Luckily, antioxidants can minimize free radical damage.

Increased collagen absorption and the ability to fight free radicals. Vitamin A packs a one-two punch!
