Aging Skin

All of that environmental exposure is what causes our skin to have the appearance of age. For most of us, when we think about aging skin, the first thing that comes to mind are the fine lines that start to appear around our eyes and mouths and the wrinkles along our brow line and chins. But the effects of aging on skin go deeper than appearance.  Aging actually prevents the skin from functioning as it should:

  • The skin’s outer layer, known as the epidermis, takes longer to recover from injury. This is because dead skin cells do not shed as quickly and turnover of new skin cells may decrease slightly
  • The outermost layer of the epidermis loses fat, making the skin drier
  • The skin's inner layer, the dermis, loses collagen, the elastic tissue that keeps the skin plump and protects it against injury
  • The skin also loses elastin, the substance that enables skin to snap back into place, and hyaluronic acid, which allows the skin to retain moisture
  • The sweat glands become less efficient at producing sweat, increasing the amount of time it takes to cool off the body on a hot day
