Sublime Radiofrequency (RF) skin tightening is a non-invasive treatment used to tighten and rejuvenate the skin. It works by delivering RF energy to the deeper layers of the skin, heating the collagen fibres and causing them to contract, which in turn stimulates the production of new collagen over time. This tightening effect works to reduce the appearance of fine lines, wrinkles, and sagging skin, leading to a smoother, firmer, and more youthful appearance.
