The massage technique that involves an invigorating rubbing that stimulates the circulation and glandular activity of the skin is called ________.

The massage technique described involves an invigorating rubbing that stimulates circulation and glandular activity within the skin. This aligns perfectly with friction techniques. Friction is characterized by applying pressure and moving the skin in a circular or back-and-forth motion, which enhances blood flow and encourages the body's natural processes. This method can promote lymphatic drainage and is often used to warm up the muscles and improve elasticity, all of which support overall skin health and vitality.

While other techniques like pétrissage focus more on kneading and squeezing, which can affect muscle structure rather than directly stimulating circulation, tapotement involves rhythmic tapping that can invigorate the body but may not specifically engage the skin's glandular activity to the same extent. Vibration consists of shaking motions that can stimulate the nervous system but are not as directly related to the skin's circulation and glandular response as friction techniques are. Thus, friction is the most accurate choice for this particular description.
