Quick Answer
A 1927nm thulium laser is a fiber-based aesthetic laser whose light is strongly absorbed by water in the skin. Delivered fractionally, it creates microscopic thermal zones that break down superficial pigment and stimulate collagen renewal—while keeping surrounding tissue intact. It sits between gentle non-ablative lasers and aggressive ablative resurfacing, with recovery measured in days rather than weeks.
ประเด็นสำคัญ
- The 1927nm wavelength targets water, making it ideal for superficial pigmentation, sun damage, and texture—concerns concentrated in the upper skin layers.
- Contrary to most marketing pages, the 1927nm thulium laser is not purely “ไม่ระเหย”: imaging research shows it spans a semi-ablative spectrum from 3mJ to 20mJ pulse energy.
- Clinical studies report meaningful improvement in melasma, photoaging, and post-inflammatory hyperpigmentation, with a favorable safety profile across Fitzpatrick skin types II–VI.
- For clinics, the economics are compelling: low consumable costs and 1–3 day downtime enable high treatment volume—fractional resurfacing procedures grew 71.9% year-over-year in the U.S. in 2019.
- Buyers should verify measured tip output (not rated power), wavelength accuracy, and FDA 510(k) or CE documentation before ordering.
What Is a 1927nm Thulium Laser?
A 1927nm thulium laser is a solid-state fiber laser doped with thulium (Tm), a rare-earth element that amplifies light at a wavelength of 1927 nanometers—invisible, near-infrared light. In aesthetic medicine, this wavelength has become one of the most popular choices for fractional skin resurfacing, particularly for pigmentation correction, texture refinement, and low-downtime rejuvenation.
One clarification worth making upfront: “thulium” และ “1927นาโนเมตร” are not interchangeable. Thulium describes the laser medium; 1927nm describes the wavelength it emits. Thulium-based systems can also operate at other wavelengths—for example, 1940nm thulium lasers are widely used in urological surgery. When aesthetic professionals say “thulium laser,” they almost always mean the 1927nm fractional platform. To understand where this wavelength fits among CO2, erbium, and diode systems, see our overview of where thulium sits in the laser spectrum (internal link → /thulium-laser-spectrum/).

How Does the 1927nm Wavelength Work in Skin?
The mechanism is easier to follow than most spec sheets suggest. Here is the sequence, step by step:
- Energy enters the skin. The handpiece delivers 1927nm light in a fractional grid—thousands of microscopic columns rather than one continuous beam.
- Water absorbs the energy. Skin is roughly 60–70% water, and 1927nm is strongly absorbed by it. The light converts to heat within the tissue.
- Microthermal treatment zones (MTZs) form. Each micro-beam creates a controlled thermal column about 0.1–0.15mm wide, damaging targeted cells while sparing the tissue between columns.
- Damaged pigment is eliminated. Treated, melanin-laden keratinocytes are pushed upward and shed through microscopic epidermal necrotic debris (MENDs)—the “bronzing and flaking” patients see days later.
- Collagen remodeling begins. Heat in the superficial dermis triggers a wound-healing response, stimulating fibroblasts to produce new collagen and elastin over the following weeks.
Water is the primary target, but not the only one. Melanin and hemoglobin absorb 1927nm energy to a lesser degree, which contributes to the wavelength’s effectiveness on pigmented lesions and its mild photocoagulation effect on vascular redness. This multi-chromophore profile is part of why thulium laser treatment works well for mixed concerns like melasma with background redness. For a deeper technical explanation of the water-absorption physics, read our guide on how the 1927nm wavelength interacts with water (internal link → /how-thulium-laser-works/).
Non-Ablative or Semi-Ablative? What the Latest Imaging Research Actually Shows
Almost every manufacturer page labels the 1927nm thulium laser as simply “non-ablative.” The most detailed in-vivo imaging study to date suggests that description is incomplete.
In a 2025 study published in the Journal of Cosmetic Dermatology, researchers used optical coherence tomography (OCT) and line-field confocal OCT to image living human skin immediately after 1927nm fractional thulium laser exposure at different pulse energies (Wenande et al., 2025). Their conclusion: the device operates across a spectrum from non-ablative to ablative, depending on settings.
At the low-energy end (3mJ): Effects were confined near the dermo-epidermal junction—subepidermal clefts under an essentially intact stratum corneum. This is classic non-ablative behavior: pigment correction with minimal surface disruption.
At the high-energy end (20mJ): Thermal zones widened dramatically, involved the stratum corneum, and reached ablation depths into the superficial dermis—in some spots resembling the microscopic ablation zones of CO2 fractional lasers.

What this means for buyers and operators: the 1927nm thulium laser is best understood as a tunable platform. Low settings support “lunchtime facial” style rejuvenation with near-zero downtime; higher settings deliver genuine pigment correction approaching micro-ablative results—still with far less recovery than CO2. If you want to understand how delivery pattern shapes these outcomes, our article on fractional vs. non-fractional delivery (internal link → /fractional-vs-non-fractional-thulium/) covers the mechanics in detail.
What Can a 1927nm Thulium Laser Treat?
The treatment menu is broad, but honest positioning matters. The wavelength excels where problems live in the epidermis and upper dermis:
- Melasma and superficial pigmentation — its signature indication
- Sun damage — solar lentigines (sun spots), freckles, uneven tone
- Post-inflammatory hyperpigmentation (PIH) — including in darker skin types
- Enlarged pores and rough texture
- Fine lines and early photoaging
- Post-acne marks and mild textural irregularities
- Scalp and hair support protocols — as an adjunct for laser-assisted delivery of topical products
Indications, Sessions, and Typical Settings
| สิ่งบ่งชี้ | เซสชันทั่วไป | ช่วงเวลา | Energy Profile |
| Melasma / pigmentation | 3–5 | 3–4 สัปดาห์ | Low–moderate (gentle passes) |
| Sun damage / photoaging | 3 | 3–4 สัปดาห์ | ปานกลาง |
| Pore refinement / texture | 3–4 | 4 สัปดาห์ | ปานกลาง |
| เส้นเล็ก | 3–5 | 4 สัปดาห์ | Moderate–higher |
| Post-acne marks | 3–4 | 4 สัปดาห์ | ต่ำ-ปานกลาง |
What it will not do: lift significant skin laxity, erase deep wrinkles, or replace surgical intervention. Managing this expectation upfront is part of running it responsibly—and it protects your clinic’s reputation.

1927nm vs 1550nm vs CO2: Three Wavelengths, Three Jobs
Clinic owners rarely choose in a vacuum. The real question is how the 1927nm thulium laser compares to the other fractional wavelengths you could put in the same treatment room.
Three-Wavelength Comparison
| ปัจจัย | 1927nm Thulium | ~1550nm Erbium Glass | 10,600nm CO2 |
| Water absorption | High (intermediate) | ปานกลาง | สูงมาก |
| ความลึกของการรักษา | Superficial (epidermis/upper dermis) | Deeper dermis | Full epidermal ablation + dermis |
| Ablation type | Non-ablative to semi-ablative | Non-ablative | Ablative |
| การกู้คืน | 1–7 days | 2–5 days | 7–14+ days |
| PIH risk (darker skin) | Low, with proper settings | ต่ำ-ปานกลาง | สูงกว่า |
| Core strengths | Pigment, tone, sun damage | Texture, scars, collagen | Deep wrinkles, scars, dramatic resurfacing |
| Treatment positioning | High-volume, low-downtime | Moderate downtime | Premium, high-downtime |
The 1927nm and 1550nm wavelengths are complements, not competitors—this is exactly the logic behind dual-wavelength platforms like Fraxel Dual (1550 + 1927). A thulium handpiece handles pigment and surface quality; an erbium-glass handpiece handles texture and scarring deeper down. Some manufacturers, including Mico Aes, build dual-wavelength platforms on this model.

What Does the Clinical Evidence Say?
The evidence base is smaller than for CO2, but it is consistent—and worth presenting honestly.
Photoaging in Asian skin. A 2023 prospective study of 27 patients treated three times at monthly intervals found statistically significant improvements in pigmentation, fine wrinkles, pores, epidermal thickness, and elasticity; roughly 70% of patients reported satisfaction, and no patient developed post-inflammatory hyperpigmentation (Li et al., Frontiers in Surgery, 2023 ). The honest caveat: 27 subjects, no control group, no long-term follow-up. Promising and clinically consistent—not definitive proof.
Melasma. A retrospective study of 100 patients treated with the 1927nm fractional thulium laser reported meaningful improvement in melasma with a favorable safety profile (Kurmuş et al., Journal of Cosmetic and Laser Therapy, 2019).
Darker skin types. A low-energy 1927nm protocol treated post-inflammatory hyperpigmentation in Fitzpatrick skin types II–V with improvement and no paradoxical darkening (Wang et al., Dermatologic Surgery, 2022); a smaller pilot in Fitzpatrick IV patients similarly reported improvement without triggering new PIH. This is why the wavelength has earned its skin-of-color-friendly reputation—though conservative parameters and an experienced operator remain the actual safeguard. For how this evidence translates to specific concerns like pore size, see what the evidence says about thulium laser for pores (internal link → /thulium-laser-for-pores/).
Why Clinics Are Investing: The Business Case
The clinical profile only half-explains the wavelength’s rise. The other half is arithmetic.
According to statistics reported by The Aesthetic Society and cited by Dermatology Times, fractional resurfacing was the fastest-growing nonsurgical category tracked in 2019, rising 71.9% year-over-year—with 66,275 procedures performed by member surgeons (Dermatology Times, 2020). Practitioners interviewed for that report priced single 1927nm sessions around $500, with total per-treatment consumable costs of roughly $50—because thulium fiber platforms have no shot-count cartridges and no per-pulse fees.
Sample Payback Math (illustrative)
| รายการ | Figure | Source |
| Platform investment | ~$9,599 | Mico Aes product page listed price |
| Single-session price | ~$500 | Dermatology Times practitioner report |
| Consumables per session | ~$50 (topical anesthetic, disposables) | Dermatology Times practitioner report |
| Typical course per patient | 3 sessions | Clinical protocol |
| Gross margin per course | ~$1,350 | Calculated |
Add the operational angle: with 1–3 days of patient downtime, treatment slots turn over quickly, and the “lunchtime rejuvenation” positioning attracts patients who would never book a week of CO2 recovery. Several sessions of modest downtime often generate more annual revenue than one aggressive resurfacing case.

What Buyers Should Check Before Ordering
Here is where factory experience matters more than spec sheets. Having built and serviced these platforms for years, our most consistent observation is simple: a 1927nm thulium laser is only as good as its calibration, not its rated power. The laser source may be rated at 15W, but what reaches the patient’s skin is what remains after fiber, optics, and coupler losses. Some machines in the field deliver noticeably less than their brochure number.

Inside the Factory: How Mico Aes Builds and Tests Every 1927nm Thulium Laser
What we actually test before a 1927nm thulium laser leaves the floor
After years building thulium fiber laser platforms, the biggest lesson I can share is this: a 1927nm thulium laser is only as good as its calibration, not its spec sheet.
The most common problem we see—on our own line and in machines sent to us for service—is output power drift. The laser source is rated at a certain wattage, but what matters is the power at the handpiece tip after the fiber, the optics, and the coupler. Losses add up. Our 1927nm platform is rated at 15W, and on every unit we measure actual tip output with a power meter rather than trusting the diode drive current alone. The measured value is logged in the unit’s test record. If it doesn’t meet our internal acceptance criteria, the unit doesn’t ship.
Second problem: wavelength stability under heat. Thulium fiber output drifts with temperature. During our continuous aging test we run the machine at load in a warm environment and re-check output at the end. The failures that matter are the ones that pass a short bench test but drift after hours of operation—that’s the failure that shows up in a customer’s clinic months later, not in our factory.
Third: spot uniformity. Our fractional head delivers a nominal 120μm microspot, but a galvanometer scanner can produce a clean grid on paper with uneven energy across the field. We verify every handpiece with a burn-pattern test on thermal paper at multiple energy levels across the 1–300mJ range. Operators notice uneven patterns before any meter does—patients would get striped results.
Every unit ships with its test record: measured tip output against the 15W rated value, wavelength verification at 1927nm, and burn-pattern documentation. Beyond calibration, each machine is configured for its destination market—110V or 220V input, the correct plug standard, interface language, and aluminum-case export packaging. None of this is exotic. But it only happens when the manufacturer actually owns the process. If you’re comparing platforms, our guide to 7 specs to compare before buying a thulium laser (internal link → /how-to-choose-thulium-laser-machine/) turns this into a structured evaluation.
OEM/ODM and Ordering in 5 Steps
Working with a factory directly is simpler than most first-time buyers expect:
Step 1 — Requirement call. You tell us your market, intended treatment menu, volume plans, and any branding requirements. We respond with a configuration and quotation.
Step 2 — Specification confirmation. Output power, handpiece configuration, language, voltage, and plug standard are locked in writing.
Step 3 — Sample unit verification. Order one unit to validate performance and market response. Before it ships, you receive the unit’s test record: measured tip output, wavelength confirmation, and burn-pattern photos.
Step 4 — OEM/ODM customization. From minimum order quantities typically starting around 3 units: your logo, interface language, housing color, and packaging. Clinical protocol documentation in your language can accompany distributor orders.
Step 5 — QC, shipment, and training. Final quality checks, export packaging, air or sea freight with documentation handled, followed by remote installation and operator training covering parameter setup, treatment workflow, and maintenance.
ความคิดสุดท้าย
A 1927nm thulium laser is best understood as three things at once: a water-targeted wavelength that reaches exactly where pigment and early photoaging live; a tunable fractional platform whose behavior shifts from gentle renewal to genuine resurfacing as energy rises; and—judging by procedure growth and per-session economics—one of the more practical investments a pigmentation-focused clinic can make in 2026. Choose on measured performance, not rated numbers, and the platform will pay for itself in courses, not years.
From here, the natural next reads are our head-to-head thulium laser vs CO2 laser (/thulium-laser-vs-co2/) comparison and the FDA and CE certifications checklist —together they cover most buyers’ two biggest remaining questions.
คำถามที่พบบ่อย (FAQ)
Is a 1927nm thulium laser ablative or non-ablative?
Neither label tells the full story. OCT imaging research (J Cosmet Dermatol, 2025) shows the 1927nm fractional thulium laser spans a semi-ablative spectrum: at 3mJ its effects are largely non-ablative, while at 20mJ it can produce ablation-depth injury in the superficial dermis. It is more accurate to call it a tunable device than a purely non-ablative one—a point that also distinguishes it from Fraxel-type dual-wavelength systems.
What is the difference between 1927nm and 1550nm fractional lasers?
Both wavelengths target water, but 1927nm is absorbed more strongly and works more superficially—ideal for pigment, tone, and sun damage. The ~1550nm erbium-glass wavelength penetrates deeper and is favored for texture, acne scars, and collagen remodeling. Dual-wavelength platforms combine both precisely because they do different jobs.
Is a 1927nm thulium laser safe for darker skin types (Fitzpatrick III–VI)?
It has a favorable profile for skin of color because it works gently and superficially, and published studies in Fitzpatrick IV–V patients report improvement in hyperpigmentation without paradoxical darkening. That said, safety depends on conservative parameters and operator experience—machine wavelength alone is not a guarantee.
How many treatment sessions are needed, and how long is the downtime?
A typical program is 3–5 sessions spaced 3–4 weeks apart. Most patients experience redness, warmth, dryness, and fine flaking for roughly 1–7 days depending on energy settings—lighter treatments approach a “no-downtime” profile, while higher-energy pigment correction may mean several days of visible flaking. Most patients observe visible improvement after the initial recovery period, with results continuing to develop over the following weeks.
What tests does a 1927nm thulium laser go through before leaving the factory?
At minimum: measured tip output verified against rated power with a power meter, wavelength verification at 1927nm, spot-uniformity burn-pattern testing across the energy range, and a continuous-load aging test to catch failures that short bench tests miss. Ask any supplier for the unit’s test record before shipment—reputable manufacturers provide it without hesitation.
What is the MOQ, lead time, and can I OEM with my own brand?
Factory-direct terms typically start at one sample unit for evaluation, with OEM branding (logo, interface language, housing, packaging) from roughly 3 units. Standard models ship fast—our U.S. sample deliveries run 5–7 working days door-to-door with DDP service available. OEM lead times depend on customization scope and are quoted per project.
