Having facials at home is quite common these days. Many people buy some form of beauty equipment to complement treatments at home. Radio Frequency (RF) devices are entry-level choices for those who want to achieve a professional result at home. Are you aware of the principles behind each device and how to pick one that’s right for you? Check out the following guide for choosing an RF beauty device.


Radio Frequency (RF) is a form of electromagnetic wave. The principle of RF is to pass an electric current through the skin to create an electrical resistance. The heat generated from RF when applied to the skin causes collagen to contract and stimulates rebirth. This is known as collagen self-generation. During the treatment, you can see the skin firming up and getting fuller right away. The RF treatment significantly remove wrinkles, fine lines and uplifts sagging contours. We often hear about RF and HIFU in beauty treatments. But what is the difference between the two? Refer to the table below:

HIFU RF
Technology High-energy focused ultrasound Electromagnetic wave
Depth 4.5mm into muscle membrane 2-3mm into subcutaneous layer
Effect / Result Tighten and lift skin, sharpen contours and improve sagging skin Tighten skin, reduce fine lines
Frequency of use Once every 21-28 days 3-4 times a week on average (depending on the individual device)
Applicable area Tighten loose skin around the cheeks, avoid thin areas of the skin around forehead and nerve lines Improve loose skin or treat delicate areas such as the upper and lower eyelids, reduce fine lines in delicate areas such as the eyes
Suitable for Sagging contours for a lifting effect Loose skin, fine lines, or for general maintenance

What to Consider before Buying?


1. Applicable area

Select the appropriate face or beauty device according to where the device is to be applied.


2. Target skin conditions

If you have several skin problems, select an all-in-one beauty device. First-time users can choose an RF beauty device with multi modes which is easier to operate.



Functions and Modes


Most RF beauty devices are equipped with various functions and modes targeted at different skin problems. One device is all you need. Below are some common functions and modes:


1. RF

The heat generated from the RF is used to stimulate collagen self-regeneration; tighten skin, fill wrinkles, restore the skin’s elasticity and shine.


2. EMS microwave

By stimulating muscle movement, it lifts and tightens skin to restore elasticity.


3. LED light

Red light improves aging skin; blue light is suitable for oil control and reduces acne; green light lightens melanin and brightens skin.


4. Super pulse current

It promotes cellular blood circulation and metabolism, enhances the concentrated infusion of beauty essence for deep absorption.


5. Ion-in and ion-out

Voltage is used to lift out skin impurities and infiltrate skincare ingredients into the skin to enhance penetration.


6. Vibrating

Massages and relaxes skin while reducing any electrical irritation.
