Introducing NIR: The Power of Near-Infrared Light for Skin Rejuvenation

What is NIR?

NIR (Near-Infrared) technology uses the near-infrared spectrum (900-1800nm, peaking around 1300nm) to deeply heat the skin, achieving tightening and anti-aging effects.

What beauty uses does NIR have?

The 1300nm laser excels in the following beauty and anti-aging treatments:

• Skin Tightening;
• Reducing Deep Wrinkles;
• Improving Skin Texture;
• Treating Superficial and Deep Pigmentary Issues (such as photoaging).

How effective is NIR treatment?

• Skin Tightening: NIR technology heats the dermis, stimulating the contraction and regeneration of collagen and elastin fibers, improving skin laxity and fine lines, making the skin firmer.
• Skin Quality Improvement: The photothermal effect of NIR light waves enhances vascular function, improves circulation, and increases the production of collagen and elastin fibers, enhancing the smoothness and transparency of the skin, resulting in a fair and radiant complexion.
• Non-Invasive Treatment: The NIR treatment process is non-invasive and painless, suitable for multiple areas such as the face and neck, with no recovery period required after treatment.

What is the principle behind NIR treatment?

1. Deep Penetration
   • The 1300nm wavelength of NIR light can penetrate deeply into the dermis and even deeper tissues. Compared to shorter wavelength lasers (such as 808nm or 1064nm), the 1300nm wavelength can more effectively reach the deeper structures of the skin without causing excessive damage to the epidermis, making it suitable for deep anti-aging treatments.
2. Water Absorption Peak
   • The 1300nm wavelength is close to a higher absorption peak of water. Since human skin tissue contains a large amount of water, this wavelength can selectively absorb heat to act on the deep layers of the skin, producing a warming effect. This effect can stimulate the contraction of collagen and elastin fibers in the dermis, activate fibroblasts, promote the regeneration of collagen and elastin, improve skin elasticity, reduce wrinkles, and achieve anti-aging effects.
3. Thermal Action and Micro-Injury Repair Mechanism
   • The 1300nm laser can cause micro-thermal damage to the skin through non-ablative or micro-ablative methods, triggering the skin’s self-repair mechanisms, including stimulating blood circulation, enhancing the regenerative capacity of skin cells, smoothing fine lines, and tightening lax skin.

Why can NIR enhance skin translucency?

1. Collagen and Light Reflection
   • Collagen, constituting 70% of skin proteins, provides structural support, leading to smoother and firmer skin.
   • Even distribution of collagen results in more uniform light reflection, reducing shadows and enhancing skin transparency and luster.
2. Elastin Fibers and Light Scattering
   • Elastin fibers contribute to skin elasticity, with healthy fibers leading to tighter and smoother skin, reducing light scattering and increasing translucency.
3. Deep Skin Optical Properties
   • Increased collagen and elastin improve deep skin structure, reducing light scattering and enhancing light transmittance, adding to skin translucency.
4. Hydration Synergy
   • The increase in collagen and elastin is often accompanied by improved hydration, further enhancing light refraction and reflection, boosting skin transparency and shine.
5. Tangible Effects
   • Skin appears refined, firm, and plump, with more uniform light reflection, giving a more transparent and healthy appearance.

NIR enhances skin translucency by stimulating the production of collagen and elastin, optimizing the reflection and transmission of light within the skin.

How long does NIR treatment take?

NIR treatments typically last 30 minutes for medium-sized areas, such as the face. The exact duration depends on the treated area, handpiece size, and the physician’s technique.

1. Facial Treatment Time
   • Full face: 20-30 minutes
   • Partial areas (eye area or jawline): 10-15 minutes
2. Larger Area Treatments
   • Neck: 10-15 minutes
   • Abdomen or thighs: 30-60 minutes
3. Influencing Factors
   • Area size: Larger areas take longer
   • Handpiece size: Larger coverage, faster treatment
   • Treatment depth and energy: Deeper or higher energy requires slower movement, increasing duration

What should be the interval between NIR treatments?

The frequency of NIR treatments depends on individual skin conditions and treatment goals.

1. Initial Course
   • Every 2-4 weeks, for 4-6 sessions, to stimulate collagen production and improve skin firmness and elasticity.
2. Maintenance Course
   • Every 3-6 months to maintain results and prevent collagen loss.
3. Special Cases
   • For mild skin laxity or short-term enhance, intervals may be shortened under medical guidance.
   • When combined with other anti-aging therapies, the frequency of NIR treatments may be adjusted for optimal results.

What should be noted after NIR treatment?

1. Post-treatment Hydration and Sun Protection
   • Emphasis on hydration and sun protection after treatment to prevent additional UV damage.
2. Experienced Practitioners
   • It is crucial to select experienced professionals to avoid side effects from improper parameter settings.
3. Post-operative Care
   • The skin may experience minor redness and swelling after treatment, which usually subsides within a few hours. Avoid direct sunlight and use sunscreen.
4. Contraindications
   • Pregnant women, individuals with photosensitivity, and those with skin infections or open wounds should avoid NIR treatments.

Are people with different skin tones suitable for NIR treatment?

NIR is suitable for various skin tones but requires adjustments based on skin characteristics.

1. Skin Tone Features
   • Southeast Asian: Precise energy control to prevent PIH.
   • European: High tolerance, significant treatment effects.
   • African: Low energy, cautious operation, enhanced sun protection.
2. NIR Adaptability
   • NIR primarily affects deep layers, minimal direct heat impact on the epidermis, safer for darker skin.
3. Safety and Effectiveness Strategies
   • Southeast Asian: Moderate energy, monitor temperature, boost sun protection and hydration.
   • European: Higher energy density, light hydration.
   • African: Low energy, enhanced cooling,strengthen sun protection and PIH prevention.

What are the advantages of NIR treatment?

1. Non-Invasive and High Safety
   • NIR treatment causes less damage to the epidermis compared to shorter-wavelength lasers, is more comfortable, and less likely to cause inflammation or pigmentation, making it a non-invasive and safer anti-aging option.
2. Deep Penetration Ability
   • NIR light can effectively penetrate the skin, reaching the dermis to stimulate collagen regeneration, improving skin laxity and elasticity.
3. Fast and Significant Effects
   • NIR treatment is fast, known as a lunchtime beauty procedure, with significant effects that can quickly improve skin color and texture.
