Physiology of Aging

The physiology of aging on the face involves the skin, which covers our
body like an invisible shield. It also maintains body temperature, keeps fluids in
and bacteria out. It is the first line of defense.

The skin is the body's biggest organ. Continual cellular and tissue
regeneration determines its health and vitality. The top layer of the epidermis is
made up of keratin, a protein material, which is effective in absorbing harmful
ultraviolet rays before they penetrate the skin's surface. The skin needs to be kept
well-cleansed, free of ashy buildup and lubricated.

The dermis is just below the epidermis. The dermis is the skin layer most
affected by the aging process. This is where collagen and elastin is located, which
is the support system as a network of interlocking protein fibers that makes the
skin firm and resilient. Collagen is the most abundant protein in the body. It is
found in the skin and all connective tissues. It is the basic glue that binds the
cells together. As we age, it becomes increasingly rigid and inflexible.
The collapsing of collagen is what contributes to the wrinkling and
sagging of the skin. Wrinkle patterns can be inherited, but the extent of the
wrinkling has more to do with life style, unprotected exposure and general health.
As the skin ages, epidermal cell generation slows, decreasing by 50%
postmenopausal. The skin becomes thinner and less flexible. It is less able to
repair damaged cells, and less capable of retaining its moisture level. The
sebaceous glands, which discharge oil, begin cutting back as estrogen and
progesterone levels drop. With the reduction of these natural oils, the skin becomes
dry and rough, making wrinkles even more apparent.

Nature, as the law of gravity, pulls our face down as we age even though
wrinkle patterns vary from person to person. The tissue under the eyes is
extremely thin and delicate. It stretches easily to accommodate fat and fluids. As
the ligament that normally supports the protective layer under the eye weakens,
the tissue begins to sag. Sagging skin and protruding fat causes shadows, which
show up as dark circles. This typically occurs after 40.

Different types of wrinkles are caused by different kinds of stress, and as
a consequence, the treatment varies. There are 4 kinds of lines, or wrinkles that
develop on the face.
1) Wrinkles
Technically, wrinkles are the most superficial, fine lines that run in many
directions. They are primarily caused by sun damage and other stresses that dry
the skin.
2) Creases
Creases are deeper, thicker individual lines cause by movement, sleep
position and sun damage.
3) Folds
Folds are elevations on the skins surface as a result of gravity and facial
movement acting on skin that has lost subcutaneous fat and elasticity. Such
loss may be due to age or sun damage.
4) Furrows
Furrows are the reverse of folds and are similarly caused by loss of fat and
elastic tissue, as well as facial movements or repeated expressions.
The loss of skin elasticity and subcutaneous fat is the earliest natural
aging event. This affects the cheeks first, then spreads to the temples, progresses
around the eyes, and finally to the chin and neck. The condition of our skin
indicates our age, health, emotions and habits.

Acupressure uses pressing, rubbing, tapping and shaking techniques.
Acupuncture is done first then acupressure for best results.
The stomach and large intestine channels pass the face area, as well as the
head and neck, plus local points. The spleen regulates muscles on the face and the
lungs rule the skin.
Minor side effects of acupuncture on facials such as bruising, bleeding
and skin irritation do occur from time to time.
Herbal remedies can be used in conjunction with acupressure and
acupuncture.
