From a reader:
The best thing I found that takes the pain away is drinking a gallon of water starting about 4 to 6 hours before my appointment. Although there is the danger of drinking too much and getting sick, but I don’t feel a thing through out my session. It’s easy and free.
Drinking lots of water can also help with effectiveness, since the more moisture in your skin, the more effective blend and galvanic electrolysis can be.
