Thulium Laser Clinical Report: Real Patient Results (1927nm)

This clinical report documents eight real patients, ages 23 to 53, treated with fractional thulium laser at 1927nm wavelengths. Across a single session each, patients saw visible improvement in uneven skin tone, freckles, wrinkles,  pigmentations, coarse skin, melasma, and acne — with short downtime. Below is a plain-language breakdown of each case, with the full original report available to download at the end.

About This Report

The report was compiled by the device's clinical team and documents individual patient outcomes (a clinical case report). Each case lists the patient's skin concerns, the exact treatment settings used, and the observed result. The device used operates at 1927nm — the same wavelengths found in the thulium laser machines in our Laser Skin Treatment collection.

The Case Studies

Case Study 1: Moles Removal and Acne Scar Reduction

Patient: Male, 25
Skin concerns: Shallow pigmented moles, acne scars, pigmentation, coarse skin texture.
Treatment: 1927nm fractional laser across the entire face (single pass), combined with targeted CO2 laser for local mole removal. One session.
Result: Skin became noticeably finer and brighter, acne scars and pigmentation were improved, and overall skin tone appeared more even. Mild redness, swelling, and stinging occurred after treatment and resolved during recovery.

Key Takeaways Across All Six Cases

Visible improvement after a single treatment session. Every patient demonstrated noticeable improvements in skin quality, including brighter complexion, smoother texture, and more even skin tone after just one session.

Consistent, minimal downtime. Temporary redness, mild swelling, and a stinging sensation were the most common post-treatment reactions. These effects were expected and resolved within days, allowing patients to resume their normal routines with minimal interruption.

One platform, multiple treatment applications. The 1927nm Thulium Laser was successfully used to address acne, acne scars, pigmentation, freckles, melasma (chloasma), enlarged pores, uneven skin tone, skin texture, skin rejuvenation, and early signs of aging. In several cases, it was combined with 1550nm fractional laser for collagen remodeling or CO₂ laser for targeted mole removal.

Effective across different patient profiles. The cases included both female and male patients ranging from 23 to 53 years old, demonstrating consistent clinical improvements across various ages and skin concerns.

Aftercare Notes From the Clinical Team

Mild redness, swelling, and a stinging sensation immediately after treatment are normal and expected during the healing process.

Apply skin-repair products containing ceramides or niacinamide (nicotinamide) to support barrier recovery and promote healing after treatment.

Daily sun protection and a consistent skincare routine help preserve and enhance treatment results.

For patients undergoing acne treatments, maintaining healthy dietary habits may further improve long-term outcomes alongside laser therapy.

What This Means for You

These clinical cases demonstrate the versatility of 1927nm Thulium Fractional Laser technology across a wide range of aesthetic indications, from pigmentation and freckles to acne, skin rejuvenation, and texture improvement. Whether used alone or combined with 1550nm fractional laser for collagen stimulation or CO₂ laser for precise lesion removal, the treatments consistently produced visible improvements after a single session with minimal downtime. While individual results vary depending on skin condition and treatment goals, these cases provide a realistic clinical reference for what practitioners can expect when incorporating this technology into their practice.
