I have to say that 95% of my clients are amazed at what little discomfort they experience during laser procedures!
They come in with their heads pinned against the table, bracing for the worst, and after the first pulse, they can’t believe “that’s it”.
The cleaner the shave you are able to get prior to the appointment the less discomfort you will generally have. That’s not to say that it will be excruciating otherwise, you just may feel a bit more of a pulse at times.
Electrolysis has been a similar experience.
People tend to expect it to be way worse then it actually is. We need a certain amount of current to be effective, but we can also adjust the settings if needed. If you know you are sensitive you can always ask your doctor for a numbing cream to apply prior to your appointment.
