Before you go
There’s nothing to do before you go except have a shower. This is really just courtesy for your therapist! You will be able to keep your knickers on, and they may give you disposable pants.
Scrubs and body polishes are suitable and safe for just about everyone. It’s not an invasive treatment, and doesn’t involve you assuming any odd positions.
You should not have a scrub if you have cancer or if you have a fever. You should also seek expert advice if you are allergic to anything or have a skin condition of any kind. Anyone with fragile, broken or sunburnt skin is well advised to skip this treatment as well, as a very vigorous scrub may hurt more than heal, however this is really something that a good therapist will take into account. Some conditions make some products, and some kinds of scrub a bad idea for you.
As with all spa treatments, make sure you are clear about any medical condition you have, or treatment you are receiving, so that you can be sure of a treatment that is safe and appropriate for you.
