To understand why Ultrasound Waves are so good for your skin, let’s have a look at human skin. Our skin tissue consist of three layers:

1. Epidermis
2. Dermis
3. Hypodermis

1. EPIDERMIS

This is the outermost layer of the skin and is especially thick on the palms of the hands and the soles of the feet. The epidermis is only a few millimeters thick.

Within the epidermis are various layers of cells, the outermost of which is called the stratum corneum (or horny layer). This surface layer is composed of twenty-five to thirty sub-layers of flattened scale-like cells, which are continually being cast off by friction and replaced by the cells of the deeper epidermal layers. This surface layer is the real protective layer of the skin.

A normal circle of metabolism of the cells is 28 days, but aging causes this metabolic speed to be reduced by up to 40 days.  New skin cells are formed in the deepest layer within the epidermis, called the stratum germinativum. This layer is very important as no other layer can form these new cells which gradually move towards the outer layers of the skin as the stratum corneum is abraded or shed.

2. DERMIS

The dermis is a tough and elastic layer containing white fibrous tissue interlaced with yellow elastic fibres. The nutrition of the epidermis comes from the dermis. If the dermis is not healthy, the epidermis would not be healthy either.
Many structures are embedded in the dermis including:

• Blood vessels
• Lymphatic capillaries and vessels
• Sensory nerve endings
• Sweat glands and their ducts
• Sebaceous glands
• Hair follicles, hair bulbs and hair roots.

The blood vessels may vasodilate in hot weather and may be more easily seen beneath the skin. This process enables greater circulation to the skin and increases heat loss from the body, helping the body to maintain a constant temperature (part of temperature homeostasis). This process also increases the absorption rate of some chemicals, for example, organic solvents.

The sweat glands are tubular glands found in most areas of the body. They are most numerous in the palms and soles of the feet. Sweat or perspiration excreted by these glands helps cool the body in hot weather to assist in temperature regulation (temperature homeostasis) of the body.

The sebaceous glands are the oil secreting glands that help lubricate the hair shaft and outermost layer of the skin. A certain amount of oil on the skin is necessary to keep it soft and pliable. This natural oil on the skin also helps to give skin its water resistance

3. HYPODERMIS

This is the deepest skin layer. It connects or binds the dermis above it to the underlying organs. The hypodermis is mainly composed of loose fibrous connective tissue and fat. Females have a hypodermis that is generally about 8% thicker than in males.

The fatty tissue keeps our body heat not to be over vaporized. When the body contacts with the outside world, it functions as a good barrier. Fat is transformed to fatty acid and triglyceride and stored in the fatty cells. The fatty cells are responsible for composing, storing and burning fat in order to offer energy that organs or tissues need.

However, if fat deposits too much, the density of the fatty cells would become too high to be easily transformed again. The deposit fat becomes lipid cellulite tissue. Aging reduces our metabolism. Once the fat stored up, it is not easy to decompose again. Due to the reduction of metabolic speed, the older person finds it harder to lose weight than a younger person.

IN SUMMARY

Your skin is constantly regenerated every 28 days and the barrier in the middle of epidermis protects skin against the external environment and matter. The barrier is very important in order to protect skin, but has negative affect in respect of beauty treatments, because it interferes with absorption of nourishment products such as lotions and creams.

Fortunately, the high frequency ultrasound waves of our Ultrasonic Massagers can pass through skin protection and remove the waste product from pores which cannot be cleaned by facial washing. It also activates each cellular-tissue to reverse the effects of muscle's slackness and contraction functions.
