As home-use beauty devices grow increasingly popular, let’s take a look at how they work and answer some of the most common questions people have about them.

Radiofrequency Principle

(1) Stimulation of Collagen Regeneration

Collagen accounts for approximately 70% of human skin. With aging, external environmental factors, and changes in internal physiological conditions, collagen loss accelerates after the age of 30, peaks at around 50, and gradually diminishes after 60.

When skin aging occurs, it loses elasticity and luster, and wrinkles appear. The aging process of facial skin is mainly caused by the atrophy of the dermis due to the aging of epidermal cells.

(2) Stimulation of Fat Breakdown

One of the main causes of fat accumulation and obesity is the enlargement of subcutaneous fat cells, which slows fat metabolism and increases the incidence of obesity or localized adiposity.

One reason for the enlargement of subcutaneous fat cells is the reduction of collagen fibers in subcutaneous tissue.

Therefore, home-use radiofrequency beauty devices can promote blood circulation in subcutaneous tissue and speed up metabolism, thereby helping to achieve a slimming effect.

(3) Stimulation of Fiber Regeneration

Fibrous tissue, including muscles, ligaments, and other soft tissues, is an important structural component of the body.

Pathological changes or damage to these structures can lead to decreased physical function and various disorders.

For example, back pain caused by muscle injury is often due to myofascial damage.

Medical RF technology can effectively promote the repair of myofascia for therapeutic purposes.

(4) Improvement of Vascular Function

Blood vessels are among the basic material conditions that sustain life activities.

Poor blood flow increases the incidence of many diseases, such as hypertension, hyperglycemia, diabetes, atherosclerosis, thromboangiitis obliterans, varicose veins, lower extremity venous thrombosis, cerebral infarction, stroke, hemiplegia, coronary heart disease, and myocardial infarction

FAQ about Home-use RF Beauty Devices

1. Can RF beauty devices plump sunken cheeks?No. Facial hollowness is caused by bone aging, loss of muscle and fat volume. RF devices mainly act on the dermis layer and cannot reach the fat layer. They only use thermal energy to stimulate collagen regeneration in the dermis for anti-aging effects.
2. Are RF beauty devices just a placebo?Home-use RF devices are not placebos. They work effectively with consistent use.By delivering thermal energy to heat and stimulate collagen to contract immediately, they help tighten and lift the skin, promote collagen regeneration, and improve skin aging.
3. Is higher temperature better for RF devices?No. The safe threshold for the epidermis is 43°C.The ideal temperature for RF to work on the dermis is around 55–56°C, which supports better collagen synthesis without damaging the skin.
4. Why does my face get red after using RF?Redness may occur if your skin is sensitive, thin, or in a fragile condition.Lower energy levels can lead to better tolerance and reduce redness.
5. What age can start using RF beauty devices?Women who care about their skin condition can start using RF devices from the age of 20–25+.Earlier use helps prevent aging in advance and maintain good skin condition.
6. Will my skin revert back if I stop using RF?Stopping RF use does not immediately return your skin to its original poor condition.However, skin naturally ages over time. Without continuous RF care, the aging process may become faster and more noticeable.
