To reduce pimples with foot massage, you need to massage the foot’s adrenal gland, kidney, ureter, uterus, liver and gall areas.
First, find out the locations of the foot’s adrenal gland, kidney, ureter, uterus, liver and gall areas on your feet, use the massage chart I provided here as a reference.
Second, use your finger, knuckle, or the end of a smooth stick to press down and apply firm pressure to that area.
Another way is stepping on a golf ball or pebbles with your bare feet, which gives you the same effect.
