Modern cosmetology offers a wide range of treatments to rejuvenate and firm the skin. One of the most popular and effective is radiofrequency (RF) treatment. This non-invasive method, often referred to as a “lift without a scalpel,” makes it possible to achieve spectacular results without surgical intervention. In this article we will take a closer look at how radiofrequency waves work, their use in cosmetics, effects and contraindications.
What are radio waves?
Radiofrequency (RF) waves are a type of radiofrequency electromagnetic radiation. Aesthetic medicine uses waves with frequencies from 0.5 to 7 MHz. During treatment, radio waves penetrate the skin and reach the deeper layers, where they generate heat. It is this thermal effect that forms the basis of radio waves in cosmetics.
How do radio waves work on the skin?
The heat generated by the radio waves causes:
- Shortening of collagen fibers: Collagen is the protein responsible for skin firmness and elasticity. When exposed to heat, collagen fibers shrink, resulting in an immediate lifting effect.
- Stimulation of fibroblasts: Fibroblasts are cells that produce collagen and elastin. Heat stimulates them to work harder, leading to an increase in the production of these proteins and improved skin density.
- Improved microcirculation: Heat dilates blood vessels, which improves blood and lymph flow. As a result, the skin is better oxygenated and nourished, and toxins are removed faster.
- Fat reduction: In some treatments, radio waves are used to reduce body fat. The heat causes fat cells to break down, which are then removed from the body.
Application of radio waves in cosmetics
Radio waves are widely used in cosmetics, both for the face and body. They are most commonly performed for:
- Wrinkle reduction: Radio waves effectively shallow wrinkles, both facial and static.
- Skin firming: RF wave treatments improve the firmness and elasticity of skin on the face, neck, décolleté, shoulders, abdomen, thighs and buttocks.
- Facial oval modeling: Radio waves can lift the facial oval and reduce so-called “hamsters.”
- Cellulite reduction: Radio waves help break down fat cells and smooth the skin.
- Scar treatment: RF waves can be used to treat acne scars and stretch marks.
Course of treatment with radio waves
Treatment with radio waves is painless and requires no special preparation. A special gel is applied to the cleansed skin, which makes it easier to move the head of the device. The beautician then applies the head to the skin and begins the treatment. During the procedure, the patient feels a pleasant warmth. The duration of the treatment depends on the area to be treated and ranges from a dozen to several tens of minutes.
Effects of treatments with radio waves
The effects of radiofrequency treatments are visible after the first treatment. The skin is tighter, firmer and smoother. Wrinkles are shallowened and facial ovals are lifted. The full effects of the treatment are visible after a few weeks, when the production of new collagen begins. To maintain the effects, it is recommended to perform a series of treatments at intervals of several weeks.
Contraindications to treatments with radio waves
Although radiofrequency treatments are safe, there are some contraindications to performing them. These include:
- pregnancy and breastfeeding
- cancers
- Metal implants in the body (pacemaker, orthopedic implants)
- Skin diseases at the treatment site (e.g., acne, eczema)
- epilepsy
- blood clotting disorders
- Liver or kidney failure
Recommendations after the procedure
After the treatment with radio waves, the skin may be slightly red and swollen. These symptoms disappear spontaneously after a few hours. In the first days after the procedure, sunbathing, sauna and swimming pool should be avoided. It is also recommended to use creams with a UV filter.
Radio waves – summary
Radiofrequency wave treatments are an effective and safe method of skin rejuvenation and firming. They allow you to achieve spectacular results without surgical intervention. If you are looking for a way to improve the appearance of your skin, radio waves are an excellent solution.
