Microchannelling has emerged as one of the most talked-about skin rejuvenation treatments in recent years, and for good reason. This advanced evolution of traditional microneedling offers impressive results with significantly less downtime. But what exactly is microchannelling, and how does it differ from other skin treatments? Let’s dive deep into the science, benefits, and everything else you need to know about this innovative procedure.
What is Microchannelling?
Microchannelling is a minimally invasive cosmetic procedure that creates thousands of microscopic channels in the skin using ultra-fine needles or filaments. These controlled micro-injuries trigger the body’s natural healing response, stimulating collagen and elastin production while enhancing the absorption of therapeutic serums.
Unlike traditional microneedling which often uses a rolling or dragging motion, microchannelling employs a vertical stamping technique. This precision approach creates uniform channels without the tearing or lateral damage that can occur with older methods, resulting in less trauma to surrounding tissue and faster recovery times.
The Science Behind Microchannelling
How Your Skin Responds
When microchannels are created in the skin, a fascinating cascade of biological processes begins:
- Immediate Response: The micro-injuries trigger an inflammatory response, sending signals to repair the perceived damage
- Growth Factor Release: Your body releases growth factors and cytokines to the treated area
- Cellular Renewal: Fibroblasts are activated, beginning the production of new collagen and elastin
- Remodelling Phase: Over the following weeks and months, the skin undergoes structural improvements
The Role of Growth Factors
Modern microchannelling treatments often incorporate specialized serums containing growth factors derived from various sources, including stem cells. These bioidentical proteins include:
- Transforming Growth Factors (TGF-β): Essential for collagen synthesis and wound healing
- Epidermal Growth Factor (EGF): Promotes cell growth and differentiation
- Platelet-Derived Growth Factor (PDGF): Stimulates cell division and tissue repair
- Fibroblast Growth Factor (FGF): Encourages new blood vessel formation and collagen production
These growth factors work synergistically with the microchannelling process, accelerating healing and maximizing results.
Microchannelling vs Traditional Microneedling: Key Differences
While both treatments work on similar principles, there are several important distinctions:
Technique and Technology
Traditional Microneedling:
- Uses rolling or pen-like devices with standard needles
- Creates channels through a rolling or vibrating motion
- Needle depths typically range from 0.5mm to 2.5mm
- May cause micro-tearing of the skin
Microchannelling:
- Employs stamping devices with ultra-fine filaments
- Creates precise vertical channels
- Can achieve depths as shallow as 0.3mm for delicate areas
- Minimal lateral damage to skin
Comfort and Downtime
The vertical insertion method of microchannelling typically results in:
- Less discomfort during treatment
- Reduced bleeding and bruising
- Faster healing (usually 24-48 hours versus 3-5 days)
- Lower risk of post-inflammatory hyperpigmentation
Enhanced Serum Delivery
Microchannelling’s uniform channel creation allows for optimal absorption of topical treatments. Studies show that microchannelling can increase product absorption by up to 300%, making it an excellent delivery system for therapeutic serums.
What Can Microchannelling Treat?
This versatile treatment addresses numerous skin concerns:
Aging and Texture Concerns
- Fine lines and wrinkles
- Loss of skin elasticity
- Rough or uneven texture
- Enlarged pores
- Crepey skin
Pigmentation Issues
- Sun damage and age spots
- Melasma
- Post-inflammatory hyperpigmentation
- Uneven skin tone
Scarring
- Acne scars (particularly effective for rolling and boxcar scars)
- Surgical scars
- Stretch marks
- Trauma-related scarring
Other Conditions
- Rosacea (when using appropriate protocols)
- Hair loss and thinning (scalp treatments)
- Overall skin dullness and lack of radiance
The Treatment Process: What to Expect
Pre-Treatment Preparation
Before your microchannelling session:
- Discontinue retinoids and exfoliating acids 3-5 days prior
- Avoid sun exposure and tanning
- Stay hydrated and maintain healthy skin
- Inform your practitioner of any recent injectable treatments
During the Treatment
A typical microchannelling session follows these steps:
- Cleansing: Thorough removal of makeup and impurities
- Numbing (optional): Application of topical anesthetic if needed
- Treatment: Systematic microchannelling across target areas
- Serum Application: Immediate application of growth factor serums
- Soothing: Application of calming products and sun protection
Most sessions last 30-45 minutes, with many clients describing only a mild prickling sensation.
Post-Treatment Care
Proper aftercare is crucial for optimal results:
First 24 Hours:
- Avoid makeup for at least 90 minutes post-treatment
- Keep skin clean and moisturized
- Skip active skincare ingredients
- Protect from sun exposure
Days 2-7:
- Gentle cleansing only
- Hydrating products recommended
- Gradual reintroduction of regular skincare
- Continued sun protection
Long-term:
- Maintain results with quality skincare
- Stay consistent with sun protection
- Consider maintenance treatments
Understanding the Results Timeline
Results from microchannelling develop progressively:
- Immediate: Many notice an instant “glow” from increased circulation
- Week 1-2: Initial improvements in texture and tone become visible
- Week 4-6: Significant changes in fine lines and pigmentation
- Month 3-6: Maximum collagen remodelling and dramatic improvements
Most practitioners recommend 3-6 initial treatments spaced 3-4 weeks apart, followed by maintenance sessions every 3-6 months.
Who is an Ideal Candidate?
Microchannelling suits most skin types and tones, but ideal candidates:
- Have realistic expectations about results
- Are committed to proper aftercare
- Don’t have active skin infections or inflammations
- Haven’t used isotretinoin recently
- Aren’t pregnant or breastfeeding
Those with certain conditions should consult carefully with practitioners:
- Active acne outbreaks
- Keloid scarring tendency
- Blood clotting disorders
- Immunosuppression
Combination Treatments and Protocols
Microchannelling works exceptionally well in combination with other treatments:
Complementary Treatments
- LED Light Therapy: Accelerates healing and reduces inflammation
- Chemical Peels: Can be alternated between microchannelling sessions
- Radiofrequency: Addresses skin laxity alongside texture concerns
- Injectable Treatments: Wait at least 2 weeks between treatments
Treatment Protocols for Specific Concerns
For Acne Scarring:
- More aggressive depths (1.0-1.5mm)
- 4-6 treatments recommended
- May combine with subcision for deep scars
For Melasma:
- Gentler approach with shallower depths
- Focus on barrier repair
- Incorporation of brightening serums
For Anti-Aging:
- Medium depths (0.5-1.0mm)
- Emphasis on growth factor serums
- Regular maintenance crucial
Risks and Considerations
While generally safe, potential side effects include:
- Temporary redness and swelling
- Minor bruising or pinpoint bleeding
- Dryness or flaking during healing
- Risk of infection if aftercare isn’t followed
- Potential for post-inflammatory hyperpigmentation in darker skin tones
Choosing a qualified, experienced practitioner significantly reduces these risks.
