TMA TECHNOLOGY

TMA TECHNOLOGY

Tixel is powered by TMA (Thermo-Mechanical Ablation), a non-laser fractional treatment technology that can transfer thermal energy to the skin very quickly and safely. The energy is emitted through a matrix of tiny pyramid-shaped pins made of biocompatible materials covering a treatment area of 1cm². The pins are heated to a temperature of 400°C, similar to the temperature generated by a CO₂ laser beam when it interacts with the skin.

During treatment, the pins are introduced at a precisely controlled speed to the surface of the skin, after which the thermal energy stored in the pins is rapidly transferred to the skin upon brief contact lasting only a few milliseconds. The ensuant evaporation of water from the skin occurs instantaneously, resulting in the formation of tiny micropores in the treatment zone. The tiny pyramids hold a limited amount of energy and evaporate the upper layers of the skin in a controlled manner without causing burns or charring in the tissue, a side effect often seen with other energy sources such as laser.

HISTOPATHOLOGY

Unlike the typical micropores seen in fractional CO₂ laser treatments, Tixel micropores are free from necrotic tissue. The narrower zones of epidermal and dermal coagulation with Tixel contribute to rapid healing and treatment safety without sacrificing efficacy.

Epidermal necrotic zone measuring 330µm diameter, papillary dermal coagulation zone measuring 170µm depth.

Tixel

Epidermal coagulation zone measuring 160µm diameter, papillary dermal coagulation zone measuring 170µm of depth.

TIXEL VERSATILITY

Tixel can perform either ablative or non-ablative treatments. The extent of thermal damage generated is closely related to the choice of the tip and to pulse duration. By adjusting treatment parameters, the physician can control the extent of ablation, the thermal effect, downtime and duration of healing.
