Sound therapy

Vibroacoustic therapy is a therapeutic effect of complex-modulated mechanical vibrations. With such an effect, the body or its individual parts can "find" their own resonant frequencies, i.e. frequencies that have a physiological effect.

Thus, low-frequency vibrations selectively excite the mechanoreceptors of the skin (Pacini and Meissner corpuscles and free nerve endings) and autonomic nerve conductors. Medium-frequency vibrations affect the vessels, and high-frequency vibrations affect the smooth muscles. Such frequency-selective action reflexively causes the expansion of the vessels of the dermis and activation of microcirculation, reduction of edema and increase in turgor of the dermis. It is assumed that vibroacoustic effects activate venous and lymphatic outflows due to the effect on valves (vascular pumps), which pass liquid only in one direction.

Melomassage (from the Greek melos - song, melody) is a sliding massage of the face and body with sounding tuning forks. When working on the face, a frequency of 128 Hz is used, corresponding to the frequency of oscillations of the facial muscles. When working on the body, low-frequency vibration (up to 40 Hz) is usually used, which excites encapsulated mechanoreceptors that form reflex reactions of activation of local blood and lymph flow (sliding micro-pumping) and relax tense superficial muscles with a subsequent increase in their tone.

Melomassage is effective for all conditions that are accompanied by swelling of the face and neck, such as postoperative swelling or physiological swelling around the eyes.

Ultrasound therapy is the use of ultra-high frequency sound waves (ultrasound) in the range from 500 to 3000 kHz for therapeutic and prophylactic purposes. Ultrasound is able to penetrate the skin, and the depth of penetration will depend on its frequency: the higher the frequency, the worse the penetration. Thus, ultrasonic waves with a frequency of 800–1000 kHz reach a depth of 8–10 cm, and with a frequency of 2500–3000 kHz - a depth of 1–3 cm.

Ultrasound waves used for therapeutic purposes are propagated in a conical beam; the space penetrated by them is called a sound field. Skin, like any biological tissue, is a heterogeneous system and consists of different structures (media) with different acoustic conductivity. When ultrasound passes from one medium to another, refraction and/or reflection of waves is observed. Thus, refraction of ultrasound rays occurs at the boundary of the epidermis-dermis, subcutaneous fat-muscle media. Subcutaneous fat has the lowest absorption capacity, while muscles, nerves, and bone tissue have the highest. Energy absorption increases at the boundary of different tissues.

Indications for the use of ultrasound therapy in cosmetology are cellulite, hyperpigmentation, degenerative-destructive diseases of the joints, consequences of injuries, inflammatory diseases of the skin and muscles, smoothing of wrinkles, atopic dermatitis, trophic ulcers.

Music therapy. Stress is an inevitable companion of man. Arising for various reasons and in different situations, it affects our body, disrupting harmony and psycho-emotional status. It is ineffective to tidy up the skin and appearance of a person whose soul is in disarray.

A good cosmetologist is also a subtle psychologist. Any methods that restore harmony and improve mood are good for "treating" the soul. The healing power of sound lies in its beneficial effect on our inner world: good music, the sounds of nature (birds singing, the sound of water, the rustling of leaves) relieve stress and improve mood.

Often, a cosmetic procedure is accompanied by music. In the SPA concept, music occupies such a significant place that it is given a lot of attention - to the point that special melodies are written to create an atmosphere of relaxation. How can one not recall the expression "music of the soul"!
Sound destruction

Ultrasonic peeling is a common method of cleansing facial skin using physical effects. Exfoliation of horny scales from the skin surface (desquamation) is controlled by enzymes (including chymotrypsin), which destroy intercellular connections. In turn, the activity of chymotrypsin depends on the water content, since it can only work in a liquid environment.

One of the ways to break the bonds between the horny scales and speed up peeling is the effect of intense ultrasound waves, causing boiling (cavitation) of the contact medium applied to the skin. This in turn leads to the destruction of desmosomes between the keratinized keratinocytes, which accelerates their peeling. Ultrasound also affects the dermis, especially its dense fibrous structures, "loosening" and accelerating their renewal. The lifting effect observed after the ultrasound procedure is primarily due to increased hydration of the stratum corneum.

Ultrasound is used to introduce drugs into the skin that inhibit hair growth. Several procedures are usually required, since the gel only affects those follicles that are in the active growth stage. This method is painless (except for preliminary waxing), but it has many contraindications. In particular, the active drug cannot distinguish hair germ cells from cells of other tissues and can destroy surrounding skin cells.
