Development of RF-technologies in cosmetology

History of development of RF-technologies

RF involves the use of a specific radio frequency electromagnetic field. This type of radiation is a form of actinotherapy. The technique results in the thermolipolysis of adipose tissue, reducing the visibility of cellulite and rejuvenating the skin. Massage with radio waves is painless and does not cause discomfort.

n 1908, a new technique called diathermy began to be used in physiotherapy for treating musculoskeletal disorders. The application of high-frequency alternating current promoted deep tissue warming. The use of this technology led to noticeable improvements in skin condition and a reduction in the subcutaneous fat layer.

The RF methodology was first introduced into medicine by the French physiologist Jacques Arsène d'Arsonval in the 1880s.  He used spark devices created by Nikola Tesla, who had demonstrated their safety for use on the human body.

In Europe, ultra-high-frequency therapy began to be used in 1926. In 2001, there was an improved method — thermage, which a year later was approved for use in aesthetic medicine. The main advantage of thermolifting is the direct release of heat in the dermis and subcutaneous layer.

The principle of RF-technology

The technology of radio wave lifting is based on the principle of applying high-frequency electric current to the skin. This results in controlled heating of the dermis and subcutaneous fat tissue. Throughout the procedure, a specific temperature is maintained. The heating activates collagen denaturation and stimulates the synthetic activity of fibroblasts. The aesthetic effect of the procedure is based on controlled inflammation, which triggers processes of restructuring and rejuvenation.

Modern radiofrequency therapy devices generate waves that affect metabolism. Penetrating the skin they fight age-related changes, vascular netting, laxity, and enlarged pores. RF facelift provides controlled contraction of collagen fibers. The delayed results are achieved through compensatory mechanisms that stimulate the production of three-dimensional, oriented neocollagen. This process enhances youthfulness, firmness, and elasticity. Numerous clinical trials confirm significant improvements in skin appearance and visible effects following a course of radiofrequency lifting.

Generations of RF-technology

In RF lifting, aesthetic cosmetology specialists use devices from three generations:

1. Monopolar — the first generation of devices that have an aggressive but effective action.

2. Bipolar — harmless devices that provide high efficiency, especially on the skin of the face.

3. Multipolar — have a large number of electrodes in the arm, able to cover large areas of skin in a short period of time.

Technical characteristics of the equipment directly affect the degree of pain, duration and cost of the course.

RF facelift: pros and cons

Modern certified equipment for cosmetology is relatively safe and well tolerated by clients, providing the desired result. The high efficiency of RF-lifting has a number of advantages:

• persistent result for a long period;

• fast action;

• increasing effect from 2 to 6 months;

• ease of performing the procedure;

• no need for special care after the session;

• non-surgical method;

No damage is left after the session. The device prevents traumatization of the epidermis. The method does not require rehabilitation. Compliance with the protocol of RF-lifting cosmetologist, proper preparation of the skin, following the client's recommendations minimizes the possibility of side effects.

What is dangerous RF-lifting? Radio wave lifting, like other active apparatus techniques, can lead to complications. Potential disadvantages of the procedure depend on three factors: the individual's reaction and adherence to recommendations, the quality of the equipment, and the qualifications of the cosmetologist. Complications from local skin reactions may include hyperemia, slight swelling, a sensation of warmth in the treated area, tingling, and allergic dermatitis. Poor-quality device, low qualification of the specialist, the choice of the boundary intensity of the device has a number of negative consequences: burn, pain, discomfort, itching, tingling, fibrosis, subcutaneous hemorrhages.

Effectiveness

The primary biological effect of RF lifting is the heating of collagen fibers, which promotes skin densification and tightening. When exposed to an electric field, charged particles begin to oscillate, generating an electric current within the tissues. This movement causes friction between the particles, leading to the release of heat. Tissues with higher electrolyte content generate more heat.

Absorption of radio waves is more intense in subcutaneous fat, muscles, fluids, soft organs. The vibrations can be generated continuously or pulsed. Pulsed technique involves minimal thermal effect and a deeper spread of action.Fat tissue undergoes the most significant warming, while muscle tissue experiences less heating, highlighting one of the main advantages of this therapy.

RF lifting has a positive effect on blood circulation. After therapy, blood vessels expand, increasing their permeability. Thanks to this, the cells are enriched with oxygen, there is an active flow of nutrients to the tissues, lipolytic hormones.

Temperature increase promotes muscle relaxation, improving perceptual reflexes. Heat reduces blood viscosity, hemodynamic resistance. It is worth noting that these phenomena form contraindications to the procedure: rosacea, inflammation of veins, tendency to bleeding GI bleeding, coagulation disorders, heart failure, arterial hypertension.

The use of radio waves helps with anesthesia and stimulates the production of endorphins. After the procedure, the patient experiences a feeling of warmth and may notice slight redness in the treated area. RF lifting shows positive results, with noticeable improvements in the skin's appearance before and after the session.

Indications for RF-lifting

Radiofrequency skin tightening is the most effective alternative to surgery, as well as other cosmetic operations. A positive result is often noticeable after the first session. Indications for RF lifting include:

• Reduced skin elasticity on the face, arms, legs, neck, chest, abdomen, back, buttocks;

• bags under the eyes;

• wrinkles;

• «double chin»;

• cellulite;

• photoaging;

• sagging after weight loss, pregnancy;

• the presence of stretch marks;

• scars, scars, post-acne.

Hardware RF lifting provides a mild whitening effect and gentle exfoliation of keratinized cells. After the procedure, clients experience a feeling of lightness and comfort. This technique is recommended for those who are not ready for major surgical interventions but wish to reduce wrinkles and improve skin elasticity. RF lifting receives positive reviews and can be combined with most other cosmetic procedures.
