Radio frequency (RF) skin tightening is a nonsurgical and noninvasive treatment for your skin.
Radio frequency is a type of electromagnetic radiation at a specific frequency range, also
known as radio waves. Electromagnetic radiation can be classified as low energy or high energy
depending on the amount of energy released, range of wavelengths and frequencies. X-rays and
gamma rays are examples of high energy radiation. Radio frequency is the lowest energy
electromagnetic radiation. Radio waves, Wi-Fi, and microwaves are all forms of RF waves.

Radio frequency is divided into bands, from very low to very high. Very low frequencies
transmit longer distances, between 10-33 km. So, people use them mainly for communicating
voice, data and entertainment media. High frequency transmits just a little distance. So it’s this
RF generating electrical current people use to help the human body in medicine and aesthetics.
Radio frequency skin tightening uses radio frequency (RF) between 122 and 167°F (50–
75°C) to heat the deep layer of your skin known as your dermis to stimulate cutaneous
collagen, elastin and hyaluronic acid production for tightening the skin and reducing the
appearance of fine lines wrinkles and sagging skin without damaging the top layer of your skin.

To deliver heat to the dermis and the subcutis – the adipose-rich tissue beneath the
dermis, devices have different penetration depths depending on the number of electrodes, for
example, monopolar, bipolar or unipolar. Currently, Monopolar Capacitive Radiofrequency
represents the gold standard of treatments designed to tighten skin in a noninvasive trend.
The primary benefits of RF therapy are tightening your skin and getting rid of wrinkles.

And it may also help fight sun damage due to its ability stimulate the production of collagen.
The procedure normally takes less than an hour and should be nearly painless. No
downtime or post-treatment skin care is required. There might be side effects after the
treatment, for example, temporary swelling, redness, and tingling.
