Nerves & Glands
Distributed to arrector pili muscles.
Motor nerve fibers
Supplies nutrients and oxygen to the skin.
Blood
Average cell turnover rate in adults.
28 days
Chemically active atoms or molecules with unpaired electrons making them unstable.
Free Radicals
Smoking, drinking, drugs, and poor diet.
Accelerate the aging process.
Connected to hair follicle and produce oil, which protects skin surface.
Sebaceous glands
Contain only colorless corpuscles, bathe the skin cells, remove toxins and cellular waste.
Lymph
Causes stretching and damage to elastin and collagen.
UV radiation
Derived from reactions with oxygen molecules that search the body for other electrons that will allow them to become stable, neutral molecules again.
Reactive oxidants
Contracts blood vessels.
Nicotine
Help regulate body temperature and eliminate waste products by excreting sweat.
Sudoriferous glands
Ceramides, waxy lipid molecules important to the barrier function and water-holding capacity.
Glycolipids
Stimulate cell turnover and reduce visible signs of aging.
Vitamin A and AHA's
Deactivates the oxidizer and stops the oxidation from continuing.
Normal oxidation
Dilation of the capillary walls.
Telangiectasia
Found under arms and in genital area.
Apocrine glands
Lipids are reduced if skin is dry, damaged, or mature.
Lipid reduction
Aging rays.
UVA
Antioxidants help neutralize the chain reaction and stabilize the free radical's electrons.
Prevention of free radicals
Chronic vascular disorder characterized by couperose veins and congestion of the skin.
Rosacea
Found all over the body, but primarily on the forehead, palms, and soles.
Eccrine glands
Drinking lots of water to keep cells healthy.
Hydration
Burning Rays
UVB
UV exposure, unhealthy foods, chemicals, smoke, trauma from medical treatments.
Causes of free radicals
Estrogens from plants.
Phytoestrogens
