A CoolPeel laser treatment can only be done using the SmartXide Punto CO2 laser. The Tetra is the latest, most advanced CO2 laser from DEKA, a global leader in aesthetic technology. Only Tetra can control its output to deliver high energy in extremely short-pulses to deliver impressive superficial, skin resurfacing results without the lingering heat that would traditionally damage the surrounding skin. The lack of unnecessary heat is why we call it cool – get it? – and how you get an immediate aesthetic effect with minimal downtime.
