acne pits, acne scars and various traumatic scars have long plagued hundreds of millions of people around the world. These skin problems are not only aesthetic challenges, but also invisible killers that affect mental health. Traditional treatment methods such as laser grinding, chemical exfoliation and even surgical resection often have problems such as long recovery period, limited effect, and high recurrence rate. According to statistics, about 30% of acne patients will develop moderate to severe acne pits, and nearly half of them do not respond well to single laser treatment. Faced with these challenges, the field of medical aesthetics has ushered in breakthroughs in recent years. The combination treatment of RF gold microneedles and PRP autologous serum protein is becoming the gold standard for solving stubborn acne pits and scars.

1. Core principle of technology: triple synergy mechanism

RF gold microneedle: precise and controllable three-dimensional restoration

Golden microneedle technology represents a major leap in the field of microneedle therapy, and its core lies in the perfect combination of traditional microneedles and radio frequency energy. During treatment, the gold-coated microneedle array penetrates the epidermis at a precisely controlled depth, reaching the deep dermis and even the subcutaneous tissue. The gold coating not only has excellent biocompatibility, but more importantly, it can serve as an ideal conductor of radio frequency energy to ensure efficient energy transmission.
When the microneedle reaches the preset depth, the radio frequency energy released by the needle body creates a columnar thermal effect area in the dermis, and the temperature can be accurately controlled between 55-65℃. This temperature range is exactly the optimal temperature point for collagen denaturation and reorganization. It can not only effectively stimulate collagen contraction, but also activate fibroblasts to produce new collagen, elastic fibers and hyaluronic acid8. It is worth noting that the 3DEEP multi-phase control technology adopted by the latest generation of equipment outputs energy simultaneously through six radio frequency transmitters to ensure uniform distribution of thermal stimulus and avoid uneven hot spots common to traditional dot matrix lasers.
The unique advantage of gold microneedles is that their layered and controllable microneedles depth can be flexibly adjusted according to different treatment areas: shallower depths are used to improve fine lines and pores; medium depths are suitable for acne pit repair; and deep treatments can effectively improve stretch marks and skin relaxation. At the same time, because energy is concentrated below the tip of the needle, the epidermis is only slightly injured by microneedle puncture, which greatly reduces the risk of pigmentation and is especially suitable for Asian skin types.

PRP Autologous serum protein: activates the skin’s self-regeneration potential

The core value of PRP lies in the high concentration of growth factors it contains, including:

• Platelet-derived growth factor (PDGF): promotes fibroblast proliferation and angiogenesis
• Transforming growth factor-β(TGF-β): Stimulate the synthesis of collagen and extracellular matrix
• Epidermal growth factor (EGF): Accelerate epidermal regeneration and barrier repair
• Vascular endothelial growth factor (VEGF): Improve local microcirculation

Collaborative mechanism of combination therapy: 1+1>2 Doubling effect

The combination of RF gold microneedles and PRP is by no means a simple superposition, but produces a two-way synergistic and mutually reinforcing physiological effect:

• Microneedle channels enhance PRP penetration: The fine channels created by the gold microneedles provide a highway for macromolecular growth factors in PRP to directly enter the dermis“”, greatly improving the transdermal penetration rate of the active ingredients. Experimental data shows that introduction of microneedles can increase the retention rate of growth factors in the dermis to more than 20 times that of traditional application.
• Radio frequency heat stimulation enhances PRP activity: Moderate heat effects not only stimulate collagen remodeling, but also activate heat shock proteins and enhance cell responsiveness to growth factors. Studies have found that thermal stimulation at 42-45℃ can increase the sensitivity of fibroblasts to TGF-by 3 times.
• PRP alleviates thermal injury and promotes healing: Growth factors accelerate the healing process of microneedle wounds, reduce postoperative redness, and inhibit the risk of post-inflammatory pigmentation (PIH) that may be caused by radio frequency.

The clinical advantages of this combination treatment have been fully verified in the actual case of Zhongnan Hospital of Wuhan University: a 32-year-old female patient left a deep and large acne pit after severe acne, and the previous dot matrix laser treatment had poor results. After receiving three RF gold microneedles combined with PRP treatments, the acne pits were significantly improved, and the recovery period was shortened by nearly 40% compared with laser alone.

 

2. Applicable population: Scientific guidelines for safe treatment

RF gold microneedle +PRP combination treatment is especially suitable for the following five groups of people:

1. Patients with refractory acne pits : Especially for those with sunken scars of icicle and van models, traditional laser treatment has limited effect. Combination therapy significantly improves the appearance of potholes through Collagen remodeling and Dermal thickening
2. Hypertrophic scar troubled : Prominent scars formed after surgery or trauma can be smoothed and softened by Scar softening needle (containing hormone or 5-FU) and then received combination treatment to optimize the surface texture
3. Early and mid-term skin aging : Regarding problems such as Skin relaxation Increased fine lines Large pores and other problems occurring between the ages of 25 and 45, Combination treatment can simultaneously achieve tightening, rejuvenation and texture improvement
4. Stretch marks/growth marks : Especially in the red stripe stage (early stage), the effect is better. Dermal collagen regeneration can repair broken elastic fibers
5. Patients with recurrent active acne: Radio frequency energy inhibits sebaceous gland activity and reduces oil production;PRP regulates the local microenvironment and reduces inflammation recurrence
