What is the difference between the manual method of application and the technician who uses a machine?
A. Each technician is familiar with certain tools and may feel more comfortable using the manual method over a machine. I personally know all three modalities (hand method, rotary and coil machine) as well as teach with all three. But, I prefer using a machine for all applications. I find that using a machine will penetrate the skin much more quickly which in turn, will deposit the pigment into the dermal layer of skin causing less trauma and discomfort to the client.
