With age, the most intuitive changes in the body are often reflected in the skin. When we look in the mirror, the fine lines, loose contours, and inelastic skin that gradually appear are silently telling that we’re getting old. Behind these signs of ageing, there is a key biochemical process, that is, the loss of collagen.
In the face of this irreversible physiological process, modern cosmetic medicine has been exploring effective intervention methods. The emergence of fractional RF technology provides a scientific and efficient solution for collagen regeneration. This article will deeply explore the relationship between collagen and skin ageing, and introduce in detail how the microneedle can achieve the rejuvenation and reversal of the skin through the perfect combination of radio frequency and microneedle.
1. The Deep Relationship Between Collagen and Skin Ageing
1.1 The Core Role of Collagen in Skin Structure
To understand the mechanism of skin ageing, we first need to understand the core function of collagen in skin structure. The skin is divided into three layers: epidermis, dermis and subcutaneous tissue, and collagen mainly exists in the dermis, accounting for 75%-80% of the protein content of the dermis. It is like a sophisticated three-dimensional network, which not only provides mechanical support for the skin, but also participates in key physiological processes such as cell proliferation, differentiation, migration and survival.
Collagen fibres are intertwined into a mesh structure, which forms a “spring system” of the skin together with elastic fibres. This system gives the skin two key characteristics: tension and elasticity. The tension allows the skin to resist gravity stretching and maintain a tight contour. The elasticity ensures that the skin can be restored to its original state after being stretched or squeezed. When the system is sound, the skin is full, smooth and shiny.
1.2 The Cycle Law of Collagen Loss
The loss of collagen does not occur suddenly, but follows a specific life cycle. From a physiological point of view, the metabolism of collagen is a dynamic balancing process – old collagen is decomposed and new collagen is synthesised. However, this balance is gradually broken with age.
20 Years Old: The Quiet Beginning of Ageing
Many people think that anti-ageing is something after the age of 30, but scientific research reveals a cruel fact: when women are 20 years old, collagen has begun to age. During this period, the synthesis rate of collagen began to slow down, while the decomposition rate remained unchanged or increased slightly, resulting in the beginning of net loss. Although it is difficult to detect with the naked eye, subtle changes have occurred in the bottom layer of the skin.
25 Years Old: The Turning Point of Loss
25 years old is the key node of collagen loss. Research shows that at this time, collagen loss reaches its peak, and the decomposition rate obviously exceeds the synthesis rate. This is also why most people find the fine lines in eye round, forehead and other parts from this age. The self-healing ability of the skin begins to decline, and the recovery time after staying up late becomes longer. These are the external manifestations of the accelerated loss of collagen.
40 Years Old: The Grim Reality of Losing More Than Half
By the age of 40, the collagen content in a woman’s body is less than half of that at the age of 18. This data comes from the statistical results of many clinical studies, which means that the supporting structure of the skin has been seriously weakened. At this stage, the facial contour begins to blur, the wrinkles deepen, the mandible line relaxes, and the wrinkles change from dynamic to static, which can be clearly seen even when the face is expressionless. The deep wrinkles on the faces of the elderly are the inevitable result of the large loss of collagen.
2.Fractional RF Microneedle: New Anti-Ageing Technology
The core principle of fractional rf microneedle equipment is to combine microneedle puncture with radio frequency energy. It opens the skin microchannel through the physical and mechanical stimulation of the microneedle, and at the same time, the needle tip releases precise and controllable radio frequency energy to heat the dermis.
This double stimulation of “mechanical + thermal energy” can accurately activate the self-repair mechanism of the skin. When the skin is slightly damaged, it will start the healing process, synthesise a large number of new collagen and elastic fibres, and rearrange them, so as to fill wrinkles and improve skin quality. The thermal effect of radio frequency can also promote local blood circulation, accelerate metabolism, and improve the skin condition from the root cause.
3. The Core Advantages of Fractional RF Microneedle
3.1 Accurate and Controllable, Personalised Treatment
The fractional rf microneedle device supports multiple parameter adjustment. The length of the needle tip can be adjusted with an accuracy of 0.1mm in the range of 0.3mm to 3mm, which means that the operator can accurately deliver energy to the corresponding skin layer (epidermis or dermis) according to the treatment site (such as around the eyes, cheeks) and skin problems. In addition, the equipment provides a variety of needles such as 25 needles, 49 needles, 81 needles, etc. to meet different treatment needs and realise real personalised solutions.
3.2 The Energy Goes Directly to the Target Tissue, and the Epidermis is not Damaged
The device adopts a needle insulation design, releasing radio frequency energy only at the tip of the needle. This key technology ensures that 100% of the radio frequency energy accurately acts on the target dermis, and the energy does not flow through the epidermis. Therefore, the epidermis will not be damaged by heat, there will be no scabs after treatment, and there will be no risk of colour sinking, which greatly improves the safety and comfort of treatment, and postoperative care is also simpler.
3.3 Dual Treatment Mode, Widely Used
The equipment is usually equipped with two types of treatment heads: dual max SRF handpiece and microneedle handpiece. This design enables the equipment to flexibly respond to the diverse needs of different customers, from acne scars, stretch marks to facial firming and lifting, all of which have good effects.
3.4 The Effect is Remarkable and Long-Term
After one treatment, the increase of new collagen in the skin can reach more than 30%. Due to the continuous action of new collagen, the treatment effect can be maintained for a long time, and the effect can be maintained for more than 5 years after the complete course of treatment. Its automated output control system can ensure the uniform distribution of energy in the dermis, making the treatment effect more stable and ideal.
FAQ
Q: Will the fractional rf microneedle treatment be very painful?
Epidermal anaesthetic cream is usually applied before treatment to reduce discomfort. During the treatment process, there may be a slight feeling of acupuncture and warmth when the microneedle is pierced and the radiofrequency energy is released, but most people can tolerate it. After treatment, there may be a slight burning sensation on the skin, which usually subsides within a few hours.
Q: How long does it take to recover after the treatment? What are the precautions?
Due to the insulation of the needle, there is no thermal damage to the epidermis, so the recovery period is relatively short. After treatment, there is generally only slight redness and swelling, which usually subsides within 24 to 48 hours. After the operation, you need to pay attention to strict sun protection, use mild repair skin care products, and strengthen moisturising. At the same time, it is recommended to avoid using irritating cosmetics and exoliating products within a week.
Q: What skin problems can gold microneedle mainly solve? How many times do you need to do it?
Wrinkes: such as facial fine lines, fine lines, crow’s feet, etc.
Scars: such as acne pits, surgical scars, etc.
Sagging skin: large pores, loose skin on the face and neck.
Lines: stretch marks, obesity lines, etc.
The specific number of treatments varies from person to person. Generally, it is recommended to take 3-5 times for a course of treatment, with an interval of about 1 month each time, in order to achieve the ideal effect.
