Though the skin is made up of several varying elements, there are some basics that we know about.  For example, we know about collagen and elastin.  These are the things that build our skin, hold it together, and keep it from stretching out too much without snapping back into place.  In addition, we now know about peptides.  They have now replaced collagen and elastin because quite frankly you can only supplement so much in before you beat it out by finding an ingredient that actually actively produces more with limitless possibilities to some degree, especially with regular use.  Third, we’ve really come to focus on hyaluronic acid.  It’s a natural moisturizer that obviously cushions the skin as well and cushions the joints.  All of these decrease over time, and all of these are really the elements that we need.  After all, from the beginning, our bodies are built to protect themselves.  They do this in part by using the skin, and the skin wears down over time as its protective elements wear down.  So you replace these, and therefore you are able to achieve those greater results you are looking for in general with healthy, beautiful, and truly more youthful skin.
