Collagen production to firm the underlying structure of the skin can be performed using either RF microneedling which releases energy at various depths or via ultrasound energy transfer which does not require puncturing the skin (non-invasive). Ultrasound waves can penetrate through the epidermis and reach the skin’s underlying collagen layer where the energy is released and stimulates the production of collagen. This treatment is ideal for patients who only want to tighten their skin without any significant downtime. Patients who undergo ultrasound skin tightening can resume normal activities immediately after treatment, such as going to back to work, exercising and wearing make-up.
