In Toyohari acupuncture, very fine sterling silver needles are used, which are non-insertible. These manipulate the qi on the skin level. Sterilised one-time-use stainless steel needles may also be inserted to a depth of 1-2 millimetres. Sensations and the movement of qi may be felt within the body and is normally pain free.
Traditional Chinese Medicine (TCM) acupuncture may also be performed where slightly larger stainless steel needles may be inserted perpendicularly into the body, or inserted horizontally underneath the skin. Stronger needling sensations may be felt.
