The 1550nm and 1927nm wavelengths are combined in non-ablative fractional lasers to provide comprehensive skin rejuvenation.

The 1550nm and 1927nm wavelengthsare combined in non-ablative fractional lasers to provide comprehensive skin rejuvenation. The 1550nm Erbium laser deeply penetrates (up to) to remodel collagen and treat Acne scars, wrinkles, and texture, while the 1927nm Thulium laser targets superficial layers to address pigmentation, melasma, and brighten skin tone. 

Advantages of 1550nm (Erbium Fiber Laser)

• Deep Tissue Stimulation:Penetrates deep into the dermis to target deep-seated problems like acne scarring, surgical scars, and significant wrinkles.
• Collagen Regeneration:Creates microthermal zones (MTZs) that prompt collagen and elastin remodeling to improve skin tightening and elasticity.
• Safe and Controlled:As a non-ablative laser, it treats the dermis without removing the surface skin, leading to faster healing compared to ablative alternatives. 

Advantages of 1927nm (Thulium Laser)

• Surface Pigmentation Removal:High water absorption makes it extremely effective at treating superficial skin concerns, including age spots, sun damage, and melasma.
• Brighter Tone & Texture:Improves skin tone and brightness by targeting the epidermis and papillary dermis.
• Quick Treatment:Covers a higher percentage of the skin’s surface, offering faster treatment times for large areas of pigmentation. 

Combined Advantages (1550/1927 Duo)

• Full-Layer Rejuvenation:The dual treatment tackles both superficial pigmentation (1927nm) and deep texture issues (1550nm) simultaneously.
• Minimal Downtime:Both are non-ablative, keeping the stratum corneum intact, resulting in fast recovery and minimal side effects.
• Versatility:Safe for various skin types to treat acne scars, sun damage, wrinkles, and uneven skin texture. 

The Three Ways Clinics Use Dual Wavelength Fractional Laser

While every protocol should be tailored to the specific needs of each patient, MultiFrax provides clinics with three practical options that correspond to how patients present.

Option 1: 1550nm Only for Deeper Texture and Dermal Remodelling

Choose 1550nm when the main goal is collagen remodelling, scar revision, or structural textural change.

Option 2: 1927nm Only for Superficial Tone and Pigment

When brightness, clarity, and dyschromia correction are the major goals, 1927nm is the best choice for superficial delivery.

Option 3: Treat Mixed Concerns in a Single Pass

When clinically suitable, combine both wavelengths, especially for patients who want improvement in texture and tone within the same visit. This helps them avoid splitting their plan across different devices or separate treatment types.

This is the main clinical and commercial advantage: you can treat more thoroughly, without forcing patients into a compromised plan that addresses only one layer of the problem.

What 1550nm Contributes

The 1550nm erbium glass wavelength penetrates deeper into the dermis, resulting in controlled columns of thermal coagulation while leaving the epidermis intact.

This makes it especially useful for concerns that require dermal collagen activation and architectural change rather than just surface correction.

Clinically, 1550nm is typically used for:

• Acne scarring
• Fine lines and wrinkles
• Textural irregularities
• Surgical and traumatic scars
• General skin ageing, where firmness and structure are the priority

Because it works deeper, 1550nm triggers a strong wound-healing response, driving neocollagenesis over time. Patients often see progressive improvements across weeks to months, which suits clinics offering course-based treatment plans rather than one-off sessions.

Downtime is usually minimal. Erythema and oedema are expected, and patients should be advised accordingly.

What 1927nm Contributes

The 1927nm thulium wavelength is more strongly absorbed by water, resulting in a shallower penetration profile that concentrates energy in the epidermis and superficial dermis. This makes it particularly well-suited to pigmentary and tone-related concerns.

Clinics most often use 1927nm when treating:

• Sun damage
• Lentigines and dyschromia
• Melasma
• Uneven skin tone
• Superficial photoageing

Importantly, fractional 1927nm thulium has published clinical evidence supporting its use in melasma and photoageing, with studies showing improvement in pigmentation and overall skin quality when appropriate parameters and patient selection are used.

Downtime is often lighter compared with deeper fractional work, but patients should still expect short-term redness and temporary skin roughness.

When Using Both Together Makes the Biggest Difference

In real-world practice, patients rarely present with a single, isolated concern. Texture issues are often associated with pigmentation, acne scarring commonly comes with post-inflammatory colour changes, and photoageing tends to show up as a blend of dull tone, uneven pigment, and early lines.

In these circumstances, it’s limiting to treat the skin as if you have to choose one priority and ignore the rest. This is where dual-wavelength capability becomes genuinely useful in the clinic.

Clinics can build smarter treatment journeys by sequencing wavelengths across a course, alternating sessions to target different layers, or address multiple issues in a single visit when clinically appropriate.

There is published clinical evidence supporting combined 1550nm and 1927nm fractional approaches as generally well tolerated, with predictable, brief side effects. For clinics, the practical advantage is simple: you can deliver more complete results with fewer compromises, while keeping protocols personalised and results-focused.

Patient Selection and Risk Management

A dual-wavelength platform still requires careful planning, and successful outcomes depend as much on patient selection and risk management as they do on the device itself.

Assess:

• Fitzpatrick skin type
• History of pigmentary issues
• Current sun exposure and photoprotection habits
• Adherence potential and aftercare compliance
• Tolerance for downtime
• Previous inflammatory responses and healing processes

High-Risk Profiles and PIH Prevention

This is especially significant when pigment is part of the treatment goal, because dyschromia issues often overlap with a higher risk profile for post-inflammatory hyperpigmentation.

For higher Fitzpatrick types, or anyone with a history of PIH, a conservative approach is the best option: start with lower settings, consider test spots, extend intervals where needed, and maintain clear communication.

Recovery & Expectations

Pre- and post-treatment photoprotection is required. Patients should also understand that “non-ablative” does not imply “no recovery”. Setting expectations for redness, swelling, and short-term skin roughness helps to ensure satisfaction, while diligent aftercare instructions promote cleaner healing and more predictable outcomes.

Why Clinics Choose MultiFrax

From a business standpoint, MultiFrax solves a common issue for modern aesthetic clinics: expanding clinical capability without increasing device clutter, training burden, or capital spend across multiple platforms.

Instead of having one device that excels at texture and another that targets pigment, MultiFrax combines two proven non-ablative fractional wavelengths in a single platform. That supports a broader indication range while keeping workflows efficient.

The dual wavelength versatility also improves consultations. It makes it easier to explain why a patient’s concern is multi-layered and how you plan to treat it without compromise through:

• faster visible improvement in tone and clarity when appropriate
• progressive structural improvement in texture and scarring over time
• clearer course-based programmes that encourage long-term retention

Handheld Delivery for Consistent, Efficient Treatments

The handheld delivery also plays a role in efficiency. It’s simple for staff to use, comfortable to use across a full clinic list, and helps clinics maintain controlled, repeatable coverage. This becomes key when you’re standardising protocols across multiple practitioners and building course-based programmes.
