Two terms, one sentence
The American Society for Dermatologic Surgery says: "Non-invasive skin tightening procedures are non-surgical devices used to stimulate collagen production in the deeper layers of the skin." So non-invasive and non-surgical are used together. Expect to see both in the sources. Two device-based sources to read are how ultrasound facials can tighten skin and an Ultherapy overview.
