3M Cavilon No Sting Barrier Film is a unique ‘no sting’ transparent barrier film, which gives up to 72 hours of skin protection. The product protects intact, damaged or ‘at-risk’ skin from irritation.  3M Cavilon No Sting Barrier Film forms a uniform waterproof film on the skin, which is colourless and transparent for easy skin monitoring. The product contains no alcohol, so does not sting, even on severely excoriated, reddened or stripped skin. Use of the product with other barrier ointments, creams or lotions may significantly reduce its effectiveness.
