radio frequency microneedles: a technological tool to accurately combat skin aging
With the changes in lifestyle, skin problems have become increasingly prominent, especially wrinkles, sagging and scars that trouble many people. As an innovative cosmetic treatment that combines minimally invasive and energy technology, radio frequency microneedles are becoming a popular choice to solve these problems.
With the development of medical beauty technology, radio frequency microneedle therapy has attracted much attention in recent years. This technology combines microneedles and radio frequency energy to accurately improve skin slack, wrinkles, acne scars and other problems.
It pierces the epidermis through microneedles and delivers radio frequency energy directly to the dermis layer to stimulate collagen regeneration, thereby achieving the effect of tightening the skin and diluting wrinkles.
I. Working principle
The working principle of RF microneedles is based on the treatment concept of breaking first and then standing. The device penetrates the surface of the skin through extremely small microneedles, creating microscopic channels, while the tip of the needle releases radio frequency energy to the deep layers of the dermis.
This technology can be adjusted between 0.5 and 3.5 mm depending on individual skin conditions, ensuring that energy is accurately applied to the root cause of the problem.
During penetration, microneedles will form tiny radio frequency thermal damage areas inside the skin, promoting the secretion of various cytokines through mechanical stimulation and thermal effects, inducing immediate contraction of collagen and deposition of new collagen.
2. Type difference
Radio frequency microneedles are mainly divided into two types: insulated type and non-insulated type. Most of the needle bodies of insulated RF microneedles are wrapped in insulating materials, and only releases energy at the tip of the needle can effectively protect the epidermis and reduce postoperative discomfort and damage.
The entire needle body of the non-insulated RF microneedle can transmit energy, and the treatment effect of is stronger.. However, for sensitive skin, the energy intensity may need to be adjusted to avoid adverse reactions.
Depending on the treatment site, RF microneedle equipment is also divided into facial system, eye-specific and body system types. The special eye equipment adopts a 0.3mm ultra-fine needle design, which is more suitable for delicate skin around the eyes.
3. Efficacy application
Radio frequency microneedles are prominent in facial rejuvenation. Data shows that after three treatments, even deep law lines can be reduced by by 60- 70%. accompanied by the natural reset of apple muscle.
Radio frequency microneedles can also play an important role in acne scar repair. Clinical data shows that after treatment, scar improvement can reach 2-3 levels (according to the ECCA scale), and the pore shrinkage rate is on average 43%.
Radio frequency microneedles are also suitable for body shaping and tightening, such as postpartum abdominal relaxation and arm butterfly sleeves. For thin skin in the neck, there is also a special 0.8mm microneedle design to ensure safe and effective treatment.
4. Applicable population
RF microneedles are most suitable for people over the age of 25 who have anti-aging needs, as well as those with mild to moderate skin slack, wrinkles, scars, and large pores.
For early dynamic lines and lines caused by skin relaxation, the effect of radio frequency microneedles is particularly significant. It can provide a good improvement even for cases that remain stiff after filling.
Radio frequency microneedles basically do not damage the epidermis and skin accessory structures, have a short stop period, and the incidence of pigmentation is low.is especially suitable for Asian people with dark skin skin .
5. Treatment process
Retinoin products need to be stopped for one week before treatment and professional skin barrier testing is performed. Topical anesthetic will be applied for about 30 minutes on the day of treatment, and the entire treatment process will take about 30-60 minutes.
There may be slight tingling during treatment. Most people can tolerate it, which is similar to the feeling of a soft rubber band. There may be slight redness and swelling within 24 hours after surgery, and fine scabs may appear about 3 days after surgery. These are normal repair processes.
It is recommended to use a medical restoration mask immediately after treatment and avoid makeup for 3 days. Strict sun protection (SPF30 or above) for at least 2 weeks, and daily supplementation of collagen peptides can help maintain the effect.
6. Post-operative care and maintenance time
Postoperative care directly affects the final effect. The 24 hours after treatment is the golden repair period requires the use of medical restoration products; avoid using irritating skin care products for the first 3 days.
The skin may become swollen or ruddy after treatment, which usually takes about a week to recover. During this period, avoid heavy makeup or excessive skin cleaning to avoid exacerbating postoperative irritation.
Good work and rest habits and scientific home care can make the treatment effect twice the result with half the effort. The effect of RF microneedles can usually last for 1-2 years, and it is recommended to carry out regular maintenance treatment to maintain the best effect.
The radio frequency microneedle market is growing rapidly. It is expected that by 2025, the market size of commercial radio frequency microneedle systems in China will reach 12 billion yuan .
As Shenzhen, Chengdu and other places actively build medical beauty capitals, domestic radio frequency microneedle equipment has even been certified by the US FDA, marking that the domestic optoelectronic medical beauty device brand is moving towards globalization.
It is crucial to select a professional medical institution and qualified doctors for RF microneedle treatment, so as to ensure the safety and effectiveness of the treatment.
In the future, radio frequency microneedle technology will continue to develop in the direction of intelligence and comfort, bringing accurate and efficient skin treatment experience to more people.
