Wrinkles are inextricably tied to aging. Middle-aged adults regularly check for wrinkles the way teenagers check for pimples. Skin creams, medical techniques, and foods are all marketed to help reduce the effects of aging, promising to reduce or even prevent wrinkles, altogether. Whether you wear yours proudly or seek to smooth them away, you might wonder how wrinkles come about and how to slow their development without discovering the fountain of youth.


1. Root Cause of Wrinkles: Lack of Collagen

The root cause of all wrinkles is a lack or breakdown of collagen. After the age of 20, the human body produces one percent less collagen every year. Collagen lies between the epidermis and the subcutaneous tissue, in the area known as the dermis. About 80% of the dermis is made up of this connective tissue. When collagen weakens and breaks, the skin loses structure. There are many reasons why collagen bonds weaken.
