What you have to look forward to (Aging)

Signs of Aging
  • Dry skin increases. As we age our oil production goes down.  When our  skin is dry  wrinkles show more.
  • The signs of photodamage becomes more apparent, such as  hyperpigmentation & hypopigmentation, texture roughness, precancerous lesions, and increased bruising.
  • Thinning of the dermis- reduced as much as 20 % .
  • Decreased cell turnover.  Rate slows from 30% to 50% between ages 30 and 80.
  • Reduced ability to repair damage.
  • Loss of temperature control.
  • Reduced immune response.
  • Collagen content per area of skin surface decreases at 1% per year as we age, and dermis develops fragmented elastic.
  • Elastin structure changes, and the diminished capacity to support microcirculation, and skin strength.
  • Melanocytes decrease 8 % to 20% per decades which leads to increased cancer risk.
  • Hormones- estrogen slows during perimenopause and stops after menopause.  Skin is directly affected by the reduction of estrogen and has its own estrogen receptors.
