Both belong to the same family, focusing ultrasound to a point. Ulthera fires while viewing inside on an ultrasound image, so the depth can be confirmed visually, and it holds longer at twelve to eighteen months. Shurink is widely available at more clinics and has the price advantage.

Downtime is mild, about one to three days. Tingling and slight swelling are possible — a natural response as the heated spots in the deep layer heal. You can wear make-up the same day, and you only need to skip the sauna for a week until the heat has settled.
