Introduction
Laser technology has revolutionized dermatology, offering precise, non-invasive solutions for skin rejuvenation, scar revision, pigmentation correction, and more. As a manufacturer of high-end laser systems in China, Mico Aes specializes in producing professional CO2, Q-switched, and fractional laser equipment for beauty clinics, dermatologists, and medical spas worldwide.
In this guide, we explore the scientific principles, treatment strategies, and clinical applications of laser skin therapy—focusing on how to optimize results using Mico Aes’s advanced laser technologies.
I. Understanding Laser Fundamentals
1. Wavelengths & the Electromagnetic Spectrum
Laser wavelengths correspond to their positions on the electromagnetic spectrum—not the width of the beam. Different wavelengths interact with various chromophores (e.g., melanin, water, hemoglobin), allowing targeted treatments with minimal collateral damage.
2. Core Laser Effects
- Selective Photothermal Effect: Absorbed energy transforms into heat to destroy pigment or tissue.
- Mechanical Disruption: High-energy bursts create shock waves to break pigment particles.
- Photochemical Reactions: Less common, but relevant in PDT and specialized treatments.
II. Regional Parameter Adjustment in Facial Treatments
Different areas of the face have distinct needs:
- T-zone: Sebum-rich, prone to photodamage. Aggressive settings risk post-inflammatory hyperpigmentation.
- U-zone: Sensitive to pigment. Fractional CO2 lasers or RF microneedling are ideal here.
Clinical Insight: Customizing parameters by region—one of the core strengths of Mico Aes devices—ensures safety and efficacy.
III. Laser Mole Removal
A. CO2 Laser Technique
- Energy & Frequency: Higher settings allow fast carbonization while reducing surrounding tissue damage.
- Treatment Area: Shape the wound like a shallow saucer to avoid scars.
- Field Visibility: Slight over-treatment around the lesion improves visibility and control.
B. Q-Switched Laser Comparison
| Feature | Q-switched Laser | CO2 Laser |
|---|---|---|
| Mechanism | Photothermal + mechanical | Thermal ablation |
| Pulse Duration | Nanoseconds | Milliseconds |
| Recovery | Faster, low scarring | Slower, higher risk |
| Best for | Acne scars, pigment | Superficial lesions |
C. Domestic vs. Imported Lasers
- Domestic (Mico Aes): Offer flexible parameter tuning, better suited for tailored acne scar removal.
- Imported Brands: Often fixed-parameter systems, which may increase the risk of blistering and swelling.
IV. Laser Treatment for Age Spots
A. CO2 Laser Use
- Vaporize thin layers gently.
- Avoid over-penetration to prevent excessive damage.
- Allow natural regeneration to restore skin integrity.
B. Result Factors
- Standardization: Misuse leads to erythema, long recovery.
- Depth Management: Vaporizing all layers delays healing and increases pigment risk.
- Tip: Treat only 3/5 of lesion depth and let thermal diffusion complete the process.
V. Types of Age Spots & Best Lasers
| Type | Treatment |
|---|---|
| Keratotic | CO2 laser |
| Pigment-dominant | IPL |
| Low pigment | Fractional + IPL |
Key Strategies:
- IPL is ideal for superficial pigment but needs pigment accumulation.
- Pre-treat with fractional laser to improve absorption and efficacy.
VI. Managing Competitive Pigment Absorption
- Exposure Time: CO2 lasers must work in bursts <2 seconds.
- Energy Matching: Adjust energy-frequency combo (e.g., 2.5J @ 100Hz = 10J @ 25Hz).
- Hydration: Low skin moisture hinders results. Hydration infusion pre-treatment helps.
VII. Atrophic Scar Repair
A. Target Areas
- Forehead/Nose: Lack subcutaneous fat; require subcision before laser.
B. Post-Treatment Protocol
- 0–3 Days: Dry healing preferred.
- 3+ Days: Moist environment aids recovery.
Mico Aes devices provide adjustable power settings for phase-appropriate healing.
VIII. Treating Melasma with Nevus of Ota
Treat Nevus of Ota first using Q-switched lasers, then follow with melasma therapy. Allow 6-month intervals between treatments.
Barrier Repair: Limit exfoliation and switch to barrier-strengthening skincare.
IX. Superficial Scar Combination Therapy
- Step 1: Use 1064nm laser to mechanically flatten scar bulges.
- Step 2: Apply CO2 laser to stimulate collagen in recessed areas.
X. Analogy for Skin Conditions & Laser Therapy
| Skin Condition | Analogy |
|---|---|
| Barrier Damage | Soil salinization |
| Dehydration | Drought |
| Microbial Imbalance | Pests |
Future Direction: Combine lasers with chemical peels and skincare for a complete solution.
XI. Challenges of Phototherapy Alone
| Issue | Limitation | Alternative |
|---|---|---|
| Microbial imbalance | pH can’t be corrected | Microneedling + Probiotics |
| Deep pigment | IPL/laser fail | CO2 + derma roller |
XII. Microneedling Support
- Rebuilds barrier.
- Reduces PIH after laser.
- Balances skin microbiome.
In Chinese clinical practice (e.g., Yunnan), microneedling is recommended in over 90% of laser cases.
XIII. Specialized Laser Techniques
A. Q-switched Dual Mode
- Low energy: Pigment.
- High energy: Texture refinement.
B. Depressed Scar Treatment
Use Q-switched laser to precisely remove concave edges. Surrounding skin fills in naturally.
C. Acne Scars
Avoid fractional lasers for depressions. Instead, remove raised edges to flatten the surface.
D. Nevus of Ota
- No Barrier Damage: Use mild energy until subdermal bleeding appears.
- With Barrier Damage: Lightly exfoliate for regeneration—not for beginners.
XIV. Blackhead Clearance: Laser + Salicylic Acid
- Laser + BHA improves sebum clearance.
- Manual extrusion after laser ensures complete removal.
- Add lipolytic agents for deep cleansing.
XV. Fractional Laser for Hair Regrowth & Tattoos
Hair Regrowth
- Only triggers vellus hair—not effective for permanent hair restoration.
Tattoo Removal
- Must penetrate all pigment layers.
- Carbon-based inks may overheat, causing blisters or infection.
XVI. Fractional Laser Technology Highlights
A. Mico Aes COE Fractional Laser
- Excellent vaporization with minimal carbonization.
- 1.5mm spacing avoids PIH.
- Adjustable dot spacing for safety and control.
XVII. Expanding Laser Applications
A. Hemangiomas
- Dye lasers often leave residue.
- IPL + fractional combo is more effective.
B. Anti-Aging
- Fractional lasers offer visible tightening in 6–12 months.
- Outperforms ultrasound in long-term results.
C. Laser Vaporization
- 1064nm laser reduces post-lip tattoo itch and bumps.
D. Laser Selection for Scars
| Laser | Pros | Cons |
|---|---|---|
| CO2 | Smooths raised scars | Risk to epidermis |
| Q-switched | Low scarring | Requires precision |
E. Scar Combination Plan
- Fractional: For thick scars
- Subcision: For adhesion-based scars
- Q-switched: For surface recovery
F. Syringoma Treatment
- Avoid full ablation.
- Laser puncture targets sweat duct precisely.
- Multiple passes ensure safety with minimal pigment change.
