nuTHULI operates at 1927nm — a wavelength that absorbs less water than traditional resurfacing lasers, allowing it to penetrate deeper into the lower epidermis where melanin concentration is highest. This precise depth of impact makes it exceptionally effective at breaking down stubborn discoloration, melasma, and sun damage that surface-level treatments cannot reach.
Using fractional delivery, nuTHULI creates thousands of microscopic treatment channels in the skin during each pass. These micro-injuries break pigment into tiny fragments that are then naturally absorbed and cleared by the body's immune cells. At the same time, the controlled thermal stimulation triggers the skin's collagen renewal response — improving firmness, refining texture, tightening pores, and smoothing fine lines with each treatment session.
nuTHULI operates in dual mode — delivering both ablative and non-ablative effects in a single treatment for maximum remodeling with shorter recovery. Pulse widths as low as 0.1μs minimize discomfort and reduce thermal spread to surrounding tissue, keeping downtime significantly lower than traditional ablative resurfacing. The scan size is adjustable from 1x1mm to 20x20mm, with spot distances from 0.1mm to 2mm, and three scan modes — ordered, center, and random — giving practitioners full control over treatment density and pattern.
The system includes two handpieces: a fractional handpiece for precision resurfacing and collagen remodeling across facial and body zones, and a roller handpiece for efficient coverage of larger areas. The smart, intuitive control panel ensures stable and accurate parameter management throughout the session. The thulium fiber laser source has a long operational life and zero consumables, making it a cost-efficient solution for high-throughput clinics.
