RF stands for Radio Frequency, which refers to the generation of an electric current (alternating current) between the positive and negative electrodes whose magnitude and direction change periodically. The electric and magnetic fields generated by the current generate electromagnetic waves, and the period of this electromagnetic wave fluctuation is between 300KHz and 300GHz (300,000 times/second to 300,000,000,000,000 times/second). 

When the radio frequency current passes through the dermis of the skin tissue, the charged particles in the skin cells will resist the radio frequency wave, thus generating oscillations in the rapidly changing electromagnetic field and causing heat. When the heat in the dermis accumulates to a certain extent, it will destroy the existing collagen triple helix structure and cause the molecules to tighten, while the fibroblasts responsible for producing collagen molecules will produce new collagen molecules. With long-term use, the total amount of collagen in the dermis will increase, achieving the effect of wrinkle removal and tightening. 

Generally once every 3-4 days; For mature skin such as rough, dry, and aging, once every 2-3 days; For people with good skin, it can be used for daily maintenance, once every 1-2 weeks. 

The MLAY professional radio frequency beauty device uses bipolar radio frequency technology to heat the deep tissue of the skin, stimulate the production of collagen and elastin, thereby lifting and tightening the skin and reducing wrinkles. The radio frequency energy can penetrate deep into the skin layer, promote cell renewal and metabolism, and make the skin firmer and smoother. 

Initial results can be seen within 1 to 4 weeks after use, including improved skin firmness and radiance. After continued use for several months, the results will be more significant, and skin texture and elasticity will be significantly improved. 

The beauty device is designed to be suitable for all skin types, including dry, oily, combination and sensitive skin. Its gentle radio frequency energy can effectively care for a variety of skin types without causing allergies or irritation. 

The device is safe to use and has no obvious side effects. A few users may feel a slight sensation of heat or redness on the skin during initial use, but these symptoms usually subside within a few hours. Please make sure your skin is clean and free of makeup before use to prevent irritation. 

This beauty instrument is suitable for multiple parts of the face and body, including the face, neck, arms, thighs and abdomen. It can effectively improve skin sagging and wrinkles in various parts. 

When using the device, you can use a radio frequency gel or lubricant to ensure that the radio frequency energy is better transmitted and protect the skin. At the same time, it is recommended to apply a moisturizing lotion or essence after use to lock in moisture and nutrients. 

For best results, it is recommended to use it twice a week for 20-30 minutes each time. Too frequent use may cause over-irritation of the skin.
