A unique facial rejuvenation option that produces dramatic results, laser skin tightening effectively reduces the appearance of wrinkles and loose skin for a smoother and more youthful appearance. Learn more about facial skin tightening below. What Is Laser Skin Tightening? Laser skin tightening is a minimally invasive, non-surgical process that uses an infrared light source (a laser) to tighten skin by heating the collagen under the skin’s surface, causing the skin to contract (tighten). Facial skin tightening is noticeable immediately after the treatment, and there is no downtime, making this an increasingly popular procedure. Additional skin tightening occurs over the next few months, but optimal results usually require two or three treatments about a month apart.
