Microneedle growth factor introduction technology: an innovative therapy for scientifically eliminating acne pits and scars

1. Technical principle: Precise activation of skin self-healing power

1. Microneedle growth factor introduction technology is a breakthrough in the field of skin repair today. It cleverly combines the dual effects of physical stimulation and bioactive factors to provide skin problems such as acne pits and acne scars. Provides scientific and effective solutions.

• Physical activation mechanism of microneedles: During treatment, professional physicians use rollers or electric devices with medical-grade stainless steel microneedles to create countless micro channels on the skin surface. The diameter of these channels is only 1% of the hair’s length, and the depth is accurately controlled between 0.5 and 2.5 mm, just reaching the depth of the dermis layer. This controllable micro-damage can:
• activate the skin’s self-repair mechanism, initiate the wound healing process,
• stimulate fibroblast activity, promote collagen regeneration,

Significantly improve skin microcirculation, increase blood flow in the treatment area

• 2, Precise delivery of growth factors: During the golden window period when the microneedle channel remains open (about 15-30 minutes), the doctor will immediately apply or introduce a high-purity bioactive growth factor preparation. These factors directly reach the dermis layer through microchannels, bypassing the epidermal barrier, and increasing the absorption efficiency by dozens of times. Clinically commonly used growth factors include:
• Epidermal growth factor (EGF): promotes the proliferation and differentiation of epidermal cells and accelerates wound healing
• Fibroblast growth factor (bFGF): stimulates the synthesis of collagen and elastic fibers, improves skin texture

Vascular endothelial growth factor (VEGF): promotes angiogenesis, improves local microcirculation

• 3, synergistic effect: When the physical stimulation of microneedles synergize with the biochemical signals of growth factors, it can produce a triple repair effect:
• Collagen remodeling: Promote the orderly arrangement of type I and type III collagen, fill the depressions
• Epidermal regeneration: Increase the thickness of the epidermis (Clinical trials have shown that it can thicken by about 8%)

Barrier repair: Reestablish healthy skin barrier function and improve moisturizing and anti-allergic capabilities

2. Applicable population and core problems to solve

• Microneedle growth factor introduction technology is particularly suitable for solving the following skin problems:
• Various types of depressed scars: icicle type, van type, and crush type acne pits left after acne, linear depressed scars after surgery or trauma
• Large pores: Significantly improve the uneven skin quality of oval and horny pores caused by collagen loss
• : Improve skin roughness and improve overall smoothness and luster

Striped problem: Reduce the rupture of the dermis such as stretch marks, growth marks, and obesity marks

3 Standardize operating procedures: Double guarantees of safety and effectiveness

Preoperative evaluation and preparation

1. Comprehensive skin assessment: Doctors will carefully analyze scar type, depth, skin thickness and pigmentation tendency, and formulate an individualized plan
2. Skin preparation: Stop retinoin products 2 weeks before surgery to avoid exposure to the sun; sensitive muscles can be relieved and pretreated
3. Contraindications Screening: Excluding active acne, herpes, skin infections, coagulation disorders and scar constitutions

Standardized treatment process
1. Cleaning and anesthesia: After thorough disinfection with a medical grade detergent, apply compound lidocaine cream (40-60 minutes)
2. Microneedle operation:

• Select needle length and device based on scar type (Manual needle roller/electric microneedle/gold RF microneedle)
• Press in specific direction Roll evenly (lengthwise, horizontal, diagonal) to ensure comprehensive coverage of the treatment area.
• The operation time is usually 15-25 minutes, and the endpoint is petechial hemorrhage or uniform red spots.

3. Growth factor introduction:

• Immediately use a sterile cotton swab to apply a thin layer of growth factor gel to the treatment area.
• Use a finger pulp tap or a needle-free introducer to promote absorption.
• The entire process is sterile to avoid cross infection

Professional care after surgery
1. Immediate care: Apply medical grade collagen mask cold for 15-20 minutes to reduce redness and swelling reactions
2. Critical repair period (72 hours after surgery):

• Continue to use growth factor gel (3-4 times a day)
• Avoid using ordinary cleansing products and use only physiological saline to clean
• Strictly protect against physical sun (Cap, umbrella, sunscreen mask)

3. Recovery period (3-7 days):

• After the tiny scabs fall off, start using the medical repair mask
• You can add barrier repair ingredients such as high-purity ceramide
• Avoid rubbing and grabbing the treatment area

4. Preoperative and postoperative effects

Summary

Microneedle growth factor introduction technology has become the mainstream choice for acne scars and skin regeneration due to its exact efficacy, controllable safety and short recovery period. With the development of regenerative medicine, this technology has also been continuously improved, providing a scientific and reliable choice for people who pursue healthy skin. Only by strictly following medical standards, selecting formal institutions, and providing good postoperative care can the goal of skin rejuvenation be achieved safely and effectively.
