RF beauty targets tissue for heating, causing the subcutaneous collagen to shrink and tighten, while cooling measures are taken on the skin surface. The dermis is heated while the epidermis maintains a normal temperature. At this time, two reactions will occur: first, the dermis becomes thicker, and wrinkles become lighter or disappear; second, the subcutaneous collagen is reshaped, producing new collagen, and becoming firmer after one treatment.
How does RF work?
RF is an electromagnetic wave with high frequency alternating changes within a certain frequency range (3KHz~300MHz). RF technology, also known as RF skin lift, penetrates the epidermis and acts on the dermis through a rapidly alternating electromagnetic field, causing water molecules to move and rub to generate heat, heating the collagen fibers to 55~65℃ (think of it as a microwave heating food). The heat energy at this temperature can cause the collagen fibers to shrink instantly, fuse with each other, and reshape, making the dermis thicker, thereby achieving the effect of skin rejuvenation. It is essentially a thermal injury. Tissue thermal injury can also initiate the body’s wound healing response, stimulate fibroblasts, promote collagen cell production, and increase skin volume, thereby reducing or delaying skin sagging and wrinkles.
Classification of RF
RF is divided into Unipolar radio frequency and multipolar radio frequency. Unipolar radio frequency has one end connected to the skin and the other end connected to the ground through the body, forming a unidirectional active electrode to transmit current. Unipolar radio frequency has high energy, greater power, high price, deeper penetration, and more intense pain. It has significant therapeutic effect in a single session and is suitable for people with deep and large wrinkles and severely loose skin. Multipolar radio frequency contains positive and negative poles, represented by Thermolift Accent pro. Compared with Unipolar radio frequency, it has a shallower depth of action, is more controllable and safer. Suitable for people with shallow wrinkles and early-stage sagging skin.
The difference between medical and home RF
RF is an essential treatment for medical beauty and anti-aging. Medical RF is treatment-oriented, with the characteristics of “fast, fierce and accurate”, high energy and high cost. Most of them require a certain recovery period after treatment, and the pain is more obvious. The treatment risk is also greater. Therefore, it must be operated by professional and experienced doctors.
Is RF skin tightening really useful?
If you want to fight aging, you have to know why the skin ages. The skin of a 20-year-old is firm and moisturized, but the skin of a 30-year-old shows various changes: fine lines, sagging, loss of elasticity… The most important reason is that the content of collagen in the skin is gradually decreasing.
Collagen can maintain the morphological structure of our skin and tissues and organs, and can also repair damaged tissues. In particular, 70-80% of the dermis of the skin is collagen. The more collagen, the fuller and more elastic the skin.
However, as we age, our metabolism slows down, and the collagen in our body gradually decreases. At around 20 years old, the collagen content in the human body reaches its peak, which is also the best time for the skin. At the age of 40, the collagen loss is only half of that at the age of 20, and wrinkles around the eyes increase, nasolabial folds deepen, and skin elasticity decreases. This is what we call getting old. If you want to keep your skin young, you must find a way to replenish the skin’s collagen and reduce collagen loss.
This is where radio frequency comes into play.
RF is a highly penetrating electromagnetic wave. Through adjustment, it can selectively penetrate into the dermis and subcutaneous fat layer to heat the tissue cells. When the temperature reaches 45-60℃, the collagen in the dermis will shrink immediately. , and denaturation occurs, just like blanching meat in hot water, the moment the skin touches the hot water, it will shrink.
At this time, the skin will feel that it is injured and start to start the repair mechanism, secreting more collagen fibers and elastic fibers to accelerate the regeneration and synthesis of collagen. In this way, the collagen content in the dermis will be significantly increased, and the new collagen will be more It can effectively support the skin structure and smooth out wrinkles.
In simple terms,RF beauty is a beauty method that applies external stimulation to activate the potential of human skin. It is not an implant-filling beauty and will not trigger chemical reactions.
In addition to common skin beauty, skin tightening and wrinkle removal, RF can also help dissolve fat. Through the action of RF electromagnetic waves on the subcutaneous fat layer, heating and enhancing lymphatic drainage, it can improve the appearance of fat masses to a certain extent and promote fat metabolism. Repair skin scars, through the Unipolar radio frequency emission energy, form micro-peeling on the skin surface, and then act on the dermis to accelerate collagen remodeling, help scars restore flatness, and improve color difference.
Finally, let me summarize for everyone that radio frequency beauty is really effective for anti-aging and wrinkle removal. If your skin is slightly loose and has fine lines, but your current budget is limited, you can consider using radio frequency beauty devices for long-term care and improvement. If you have sufficient budget, your skin is severely loose, and you hope to see “immediate” improvement after one treatment, the radio frequency beauty program of professional institutions is more worthy of choice.
RF suitable and contraindication groups
Suitable groups
①Deeper wrinkles and mild to moderate skin relaxation: forehead wrinkles, frown lines, crow’s feet, nose root wrinkles, nasolabial folds, perioral wrinkles, neck wrinkles, etc., especially forehead wrinkles and periorbital wrinkles.
② Double jaw removal.
③RF muscle slimming: used for muscle-type calf shaping, masseter hypertrophy face slimming, etc.
④ Stretch marks and other atrophic lines.
⑤ Skin tightening after liposuction, etc.
Contraindication groups
① Local lesions such as damage and inflammation in the treatment area.
② Patients with diseases that affect conductivity such as dry skin.
③ Patients with pacemakers
Considerations for frequency of use
(1) Skin sensitivity
Everyone’s skin reacts differently to RF. Some people may experience redness or mild inflammation, while others may have no discomfort. For those with sensitive skin, it is recommended to start with a lower frequency and gradually increase to the frequency that the skin adapts to. At the same time, observe skin changes regularly and adjust the frequency of use accordingly.
(2)Maintaining the treatment effect
After achieving the desired effect. it is egually important to maintain the skin condition. Generally speaking, using a RF device once a week or every other week can help to continuously promote collagen production and maintain the skin’s firmness and youthfulness.
(3) Expert advice
Although home RF devices are generally safe and reliable, it is still a wise choice to consult a skin care expert before starting to use them. Experts can provide personalized usage frequency recommendations and other skin care recommendations based on your skin condition.
In summary, the recommended usage frequency of home RF beauty devices is 2-3 times a week, 10-15 minutes each time. But please be sure to pay attention to skin reactions and adjust the usage frequency in time according to your personal situation. With proper use and maintenance,home RF devices will become a safe and effective assistant for you to have firm and youthful skin.
Precautions for RF treatment
Before surgery
Communicate fully with the doctor. Many people who need treatment are afraid of plastic surgery because of the fear caused by lack of understanding. In fact, these concerns can be relieved by talking with the doctor.
After surgery
Wrinkle removal and stretch mark treatment
①Since the skin may be slightly peeled or dry, a mild moisturizer can be used after surgery.
② Reduce sun exposure. Although there is no need to prevent sun exposure after RF treatment, it is recommended to minimize sun exposure to prevent photoaging.
③ After RF treatment, please do not bathe in hot water within one week (water that does not exceed body temperature is fine)
④ After RF treatment, please do not take a hot spring or sauna bath for one week.
Notes on RF muscle slimming
① Try not to move the muscles in the surgical area after surgery to reduce swelling.
② If muscle weakness and soreness are obvious after surgery, you can actively exercise under the guidance of a doctor in the early stage, but once muscle strength is restored, you must stop to prevent excessive exercise from causing muscle hypertrophy.
③ After RF ablation of the gastrocnemius muscle, you need to use an elastic band for 1 month as prescribed by the doctor to help restore muscle function and shape the legs.
The essence of RF technology for skin is a kind of thermal damage. For people with sensitive skin irritation, severely damaged skin barrier, and inflammatory reactions caused by other skin diseases, both radio frequency and other anti-aging medical beauty projects should be avoided and considered after the skin barrier function is restored. The increase in temperature during the radio frequency process will accelerate the loss of skin moisture, making the skin dry after treatment. This is a normal phenomenon and requires timely replenishment of water, including drinking water and strengthening skin moisturizing care. On the premise of ensuring hydration, radio frequency can also improve skin quality by accelerating the repair of the barrier function. It does not directly stimulate or damage the skin, nor does it cause skin sensitivity. Radio frequency is an effective way to penetrate deep into the bottom layer of the skin for anti-aging.
