The purpose of the skin, the largest organ of the body, is to protect the body against external threats. Stimulating the tissue underneath the skin increases metabolic activity, reduces the formation of cellulite, and accelerates the removal of fat. Stimulating the transport of oxygen can affect the healing rate of scars because low partial pressure of oxygen may contribute to abnormal scar formation. The partial pressure of oxygen is considerably lower in hypertrophic scars originating from burn injuries than in healthy skin, possibly due to obstructed capillaries. Low partial pressure of oxygen stimulates fibroblasts to produce excess collagen. Treatment of hypertrophic scars should begin as soon as possible in order to encourage the formation of new capillaries and reduce the risk of obstruction in small blood vessels.

Stimulating subcutaneous tissue and the production of collagen with PhysioTouch or LymphaTouch therapy increases the elasticity of skin and improves its function. The treatment method can also be used to promote scar healing after surgery, for example, so that the scar will be less noticeable. The treatment accelerates healing of a surgical scar by activating lymph vessels and stimulating the transport of nutrients and oxygen in the interstitial space. PhysioTouch and LymphaTouch can even be used to treat severe burns, or wounds that are not healing properly for some reason.
