The popularity of home radiofrequency beauty devices is currently on the rise, accompanied by mixed reviews of the products. Some people say that buying beauty devices is a waste of “intellectual money”, while others praise that they can achieve similar anti-aging effects as those in beauty salons. So, can radiofrequency beauty devices truly improve the problem of skin aging?
The mechanism of skin aging and skin care needs
The skin is composed of the epidermis, dermis and subcutaneous tissue. The key to skin aging lies in the dermis layer. The dermis layer is approximately 2 millimeters thick, and the papillary layer, subpapillary layer and fibrous layer contain collagen fibers, which are the key to determining the skin condition. The dermal papillary layer is sensitive to temperature, while the collagen fiber layer is the target of radiofrequency beauty device care. The energy acts on this layer, ensuring the effect while not causing a strong burning sensation.
The causes of skin aging are diverse. Ultraviolet radiation, pathological inflammation, environmental pollution, and heavy metal damage can all damage the skin. Free radical oxidation is the main factor. When human cells generate energy through respiration, free radicals and antioxidants are produced simultaneously. Before the age of 18-20, there are more antioxidants than free radicals, and the skin condition is good; after that, free radicals prevail, and skin begins to show signs of aging. Therefore, skin care needs to focus on antioxidants, anti-inflammation and promoting metabolism.
The working principle of radiofrequency beauty devices
The working principle of radiofrequency beauty devices is to use radiofrequency energy to penetrate the epidermis and heat the collagen protein in the dermis layer, making the damaged collagen protein inactive, stimulating fibroblasts to generate new collagen protein, thereby achieving anti-aging effects such as reducing wrinkles and repairing contours.
Its professionalism lies in the research of skin cell biology, radiofrequency circuit system topology and physical parameters. If gel is involved, organic chemistry effects need to be considered. In practical applications, there are many cognitive misunderstandings. Radiofrequency does not dissolve fat because fat is non-conductive and radiofrequency energy is difficult to reach the fat layer; the depth of radiofrequency action depends on the frequency, not the distance between the electrode head; frequency has no direct correlation with heating; frequency determines the position of energy action, while the degree of heating is affected by multiple factors. High frequency is the technical difficulty and key advantage of radiofrequency beauty devices.
Function differentiation and purchase points of beauty devices
Most beauty devices on the market integrate multiple functions. The import/export function claims to assist in the absorption of skin care products, but current technology cannot achieve this without damaging the skin barrier; the microcurrent function has unclear effects; the muscle contraction and electric shock sensation it brings may have lifting effects, but it is prone to causing muscle relaxation and dependence; the ultrasonic skin exfoliation machine causes significant damage to the epidermis when cleaning the skin; LED red and blue light has limited cosmetic effects due to power limitations; IPL hair removal devices have an effective principle, but their functions are highly homogeneous.
When purchasing radiofrequency beauty devices, frequency, waveform and power are key parameters. Frequency determines the depth of energy action; 1 MHz is the basic threshold, the higher the better, above 4 MHz is close to the level of medical beauty Thermage; waveform is best with a sine wave; power, under the condition of meeting the frequency, determines the amount of effective energy. In addition, LED red and blue light can be an added feature, while EMS, import/export functions have side effects, and when purchasing, caution is needed.
Home radiofrequency beauty devices as representative products of physical skin care have certain potential in the anti-aging field. Consumers who understand the mechanism of skin aging and the working principle of beauty devices can master the purchase points and make more scientific choices for their own products, making wiser decisions in the pursuit of beauty. With the continuous progress of technology, radiofrequency beauty devices are expected to bring more possibilities to skin care in the future.
