Why The 1927nm Thulium Laser Is Popular In Europe

The 1927nm thulium laser has become increasingly recognized in Europe for its effectiveness, safety, and clinical versatility. Unlike traditional ablative lasers, it is classified as a fractional non-ablative laser, meaning it does not remove the entire epidermis. Instead, it creates controlled microscopic treatment zones that stimulate skin renewal while leaving surrounding tissue intact. This ensures minimal downtime, faster recovery, and lower risks compared with ablative technologies.

 

1. Understanding the 1927nm Wavelength

Operating at 1927 nanometers in the mid-infrared spectrum, this wavelength has a strong absorption rate in skin water. Since water is abundant in both the epidermis (10–30% content) and dermis (up to 70% content), the laser is particularly effective for superficial skin resurfacing and rejuvenation. Its penetration depth-about 200–300 microns-targets the epidermis and upper dermis with precision, making it suitable for treating pigmentation, photoaging, and early keratotic changes without causing deep thermal injury.

2. Clinical Applications and Focus on AKs/SCC

One of the most important clinical milestones of the 1927nm thulium laser is its FDA approval in Europe and the U.S. for the treatment of actinic keratoses (AKs). AKs are precancerous lesions caused by chronic UV exposure and are common among fair-skinned populations in Europe and North America. Left untreated, some AKs may progress to squamous cell carcinoma (SCC).

Because the 1927nm wavelength precisely targets the epidermis and superficial dermis, it can remove abnormal cells while encouraging new, healthy skin regeneration. This makes it a highly effective, non-invasive option for preventing skin cancer progression, especially in high-risk groups such as outdoor workers and elderly fair-skinned individuals.

3. Comparison with Other Lasers

Laser type	Wavelength	Action depth	Depth range	Ablative	Main targets	Typical Applications	Downtime
Thulium	1927nm	Epidermis & superficial dermis (200–300µm)	Middle and shallow layers	Non-ablative	water	Melasma, sun spots, skin texture improvement, photoaging, early photokeratosis (AKs)	1–3 days erythema/dryness
Er:YAG	2940nm	Epidermis & superficial dermis (10–100µm, controllable)	Very shallow – shallow	ablative	Water (very absorbent)	Superficial wrinkles, fine lines, mild acne scars, pigmentation spots	5–7 days, small wound, fast healing
CO₂	10600nm	Mid- to deep-dermis (200–1000µm+)	Medium-deep	ablative	water	Deep wrinkles, acne scars, scars, skin firming	1–2 weeks or even longer
Er:Glass	1550nm	Mid-dermis (500–1500µm)	Middle level	Non-ablative	water	Acne pits, acne scars, enlarged pores, fine lines, mild firming	2–4 days of mild erythema, no open wounds

 

Four laser wavelengths vs. water absorption

Laser type	Wavelength	Water absorption coefficient	Absorption intensity	Characteristics
Thulium	1927nm	Moderate (stronger than 1550, but much lower than 2940/10600)	Moderate	Moderate water absorption → Energy is concentrated in the epidermis and superficial dermis, a non-ablative dot matrix
Er:YAG	2940nm	Highest (about 10 times higher than CO₂)	Very Strong	Highest water absorption → Almost all energy is absorbed in the epidermis → Precise exfoliation with minimal thermal diffusion
CO₂	10600nm	Very high (lower than 2940, but much higher than 1927/1550)	Strong	Strong water absorption → Epidermal vaporization + deep thermal effect → Strong exfoliation, collagen stimulation
Er:Glass	1550nm	Low	Weak	Weak water absorption → Can penetrate the epidermis, energy is deposited in the mid-dermis → Non-ablative, primarily thermal

Comparison of four laser penetration depths

Laser type	Wavelength	Water absorption strength	Penetration depth	Characteristics
Thulium	1927nm	Very strong	Epidermis & superficial dermis (~10–100µm)	High Absorption → Almost all energy is absorbed in the epidermis → Precise exfoliation with minimal heat diffusion
Er:YAG	2940nm	Very strong	Mid-deep dermis (~200–1000µm)	Strong absorption, yet high energy, exfoliation + deep thermal effect
CO₂	10600nm	Moderate	Epidermis & superficial dermis (~200–300µm)	Non-ablative Dot Matrix → Mild thermal stimulation of collagen
Er:Glass	1550nm	Weak	Mid-dermis (~500–1500µm)	Non-ablative → Energy penetrates the epidermis → Heat is deposited in the mid-dermis for rapid recovery

 

4. Market Trends in Europe

The European aesthetic and dermatology market has shown a clear shift toward non-invasive and preventive treatments in recent years. Patients are no longer seeking only corrective procedures; instead, they are increasingly interested in maintaining healthy skin and addressing early signs of damage before they progress.

 

A key factor driving this trend is the high prevalence of photodamage and actinic keratoses (AKs) among fair-skinned populations in Europe. Northern and Western European countries, with their aging populations and history of sun exposure, report some of the highest rates of AKs and related skin concerns. Clinics are therefore prioritizing devices that can both treat visible cosmetic issues like pigmentation and fine lines while also addressing medical concerns such as precancerous lesions.

 

Another major influence is the European lifestyle and cultural preference for natural-looking results. Patients prefer gradual, subtle improvements rather than dramatic transformations. The 1927nm thulium laser aligns with this expectation by providing gentle resurfacing and skin tone correction with minimal downtime. This makes it especially attractive to professionals, executives, and active individuals who cannot afford extended recovery periods.

 

The regulatory environment in Europe also plays a role. With strict safety standards and patient protection regulations, clinics are more likely to adopt technologies that are clinically proven, well-studied, and approved for specific medical indications. The fact that the 1927nm thulium laser has official clearance for AKs enhances its credibility and encourages wider adoption.

 

Finally, the growing trend of combination treatments has further accelerated the demand for versatile platforms. European practitioners value devices that can integrate multiple wavelengths and adapt to various skin conditions in one system. This trend supports the use of dual-wavelength solutions such as 1927nm + 1550nm, which allow practitioners to customize treatments for both superficial and deeper concerns in a single session.
