YNSA acupuncture is made up of two categories of points: YNSA Basic points and YNSA Ypsilon points.
The YNSA Basic point A is located on the forehead approximately 0.5 cm from the midline of the face at the hairline. This point is also known as the A zone because it actually corresponds to an area about 2 cm wide x 4 mm high.
Prior to stimulating the A point or zone, the practitioner will carefully palpate the scalp, to determine whether there are any small hardenings or swellings within the A zone. Such swellings may feel painful or tender to the patient. If the YNSA point tests positive, it is needled with a fine acupuncture needle.
