What is the difference between the 50mm and 100mm handpieces?

The difference between a 50 mm and 100 mm CO₂ handpiece comes down to precision versus coverage. The 50 mm handpiece has a smaller spot size at 120μm, making it ideal for delicate areas, fine lines, and small scars, but it covers less area per pass. The 100 mm handpiece has a larger spot size at 240μm, allowing faster treatment of bigger areas like the full face or body, though it is less precise for small or sensitive zones.
