Didn't I just read almost this identical post a few minutes ago on the other thread? :?
cupping, it really isn't necessary to post the same thing multiple times everywhere you've been on this board.
I only use jojoba oil with glass cupping and since it is a plant ester instead of a true oil, it shouldn't break down the rubber. I'm not sure though, it might be wise to ask the manufacturer.
Massage cupping should generally be lighter the first time you use it on a new person, just to get an idea for how they will react. You should always warn about potential bruising. If the weather is warm I always ask if they will be wearing swimsuits or tanktops in the next few days because the marks could show.
With the rubber cups, you won't be able to see what is happening under the cups, so it would not be a good idea to "park" them unless you are familiar with how the client's body reacts to static cups.
I don't use any essential oils, salves or topicals with cupping until I am finished. Then I use them sparingly, unless the salve or essential oils are part of the specific treatment. The skin is a less effective barrier after cupping so topicals are more easily absorbed. This can be a positive or negative, so ask questions about sensitivities.
I find this method highly effective for tight muscles and trigger points, particularly when regular methods aren't getting the muscles to release. I've also used cupping extensively on scarring from back and hip surgeries. I'm looking forward to acquiring a manual vacuum version of glass cups to use on scars from knee surgeries, neck scarring and facial scars. The tiny glass manual vac cups should also be beneficial for loosening anterolateral neck muscles.
If you are going more for relaxation and/or esthetics treatments, cupping is really great to diminish the appearance of cellulite. It takes long, slow strokes with extra oil and moderate suction to loosen the dimples. Your clients should be advised that longer cupping sessions can result in them feeling extra tired. Also, due to the amount of fluid that is moved superficially, it is very important for them to be well-hydrated both before and after the session.
