What's Contained In One Square Inch Of Skin?

If you regularly follow my blogs and have visited my website,, then you know that I'm a licensed esthetician - a skin care specialist. I write books and articles about holistic skin and body care, create chemical-free skin care and personal care products, and teach and lecture about proper skin care plus the topics of herbalism, nutrition, and aromatherapy as they relate to skin care. I'm all about skin, you see. I thought that in this blog, instead of talking about a particular skin / health concern or offering you a nutritional tidbit or recipe to feed your skin, I'd give you the inside scoop on what one square inch of your skin contains. The following is pure structural information - anatomy and physiology 101. I'm sure you will find it fascinating! Your skin performs so many jobs - a good reason to always keep it in tip top shape.
