2. Skin Info
Contains nerve receptors that allow you to feel touch, pain, and pressure.
Helps control fluid and electrolyte balance.
Helps control your body temperature.
Protects you from the environment.

3. Skin Layers
The outer part (epidermis) contains skin cells, pigment, and proteins.
The middle part (dermis) contains blood vessels, nerves, hair follicles, and oil glands. The dermis provides nutrients to the epidermis.
The inner layer under the dermis (the subcutaneous layer) contains sweat glands, some hair follicles, blood vessels, and fat.

4. Age Effects on the Skin
Stem cell production starts to decline, causing skin cell reproduction to decrease .
Translucency, due to a decrease in melanocytes.
Prone to injuries such as tearing and infection.
Wrinkling appears when collagen and elastic fibers break, thicken, and stick together.
Dark spots
Healing process takes twice as long.

5. Age Effects on the Skin
Inability to retain heat and reduction in sweat gland activity.
Decreased protection against UV light, causing a higher chance for sunburns and skin cancer.
Skin growths
With aging, the outer skin layer (epidermis) thins even though the number of cell layers remains unchanged.

6. Hair Effects
Sebaceous gland activity decreases, affecting the amount of sebum produced, which is vital to healthy hair.
Hair follicles produce less melanin causing hair to turn gray/white.
Thinning, due to loss of estrogen and other hormones.
Becomes brittle, due to decreased production of sebum.
Balding

7. Nail Effects Nails may turn opaque or yellow.
Fingernails become brittle.
Horizontal ridges will often appear (onychorrhexis), due to less efficient blood flow to your extremities as you age.
Nail growth rapidly decreases.
Fingernails and toenails thicken, due to the the piling up of nail cells (oncocytes).

8. The Age of Old Age Twenties: Wrinkles appear Dry skin Thirties:
Balding occurs in men
More wrinkling
Lighter hair can occur
Fifties / sixties
Wrinkles have become more defined and deep within skin
Paleness
Thinning of skin
Women experience hair loss after menopause
