On the day of your Thermage treatment, we have to use cleansers and alcohol-based agents to make certain that your skin is perfectly clean prior to your procedure. During your procedure, we must use ample amounts of a fluid called "coupling fluid". Coupling fluid is a gel that is used to insure even and complete contact between the Thermage treatment tip and your skin. After your Thermage treatment, we wash all of that off for you.
All of this means that your skin has been cleaned multiple times within a few hours, so we suggest to our patients that they give their skin one good night's sleep to recover, and then resume their normal skincare regimen the next day.
