Ottobock Derma Prevent Skin Care is a special skin care and protection system for irritated and sensitive skin. Derma Prevent preserves and regenerates the skin’s natural protection and immune functions. Works great when applied to your knee cap or hamstrings along the socket trimelines.  Many above the knee amputees will apply a thin layer of Derma Prevent along the inside of their thigh just below the groin area where chafing can occur. Apply Ottobock Derma Prevent to fragile skin before putting on your prosthetic liner or prosthetic suspension sleeve for chafing relief throughout the day.
