This study was designed with the objective of evaluating the protection potential provided by the experimental product (Liquid Bandage) by evaluating its barrier formation capacity. Once the product's ability to form a barrier is confirmed, its ability to protect against small skin injuries, such as small cuts and bruises, blisters and cracks, is confirmed. The barrier formation also guarantees protection against the formation of calluses.
