Blisters are painful but avoidable

Blisters are common and easy to develop, and persistent blisters can be debilitating.

Based on a few simple principles, effective early prevention of blisters or skin damage can be performed, especially during common daily activities such as walking, running, playing ball games, wearing new shoes, and in hot or humid weather.

From the physical level, it is easier and clearer to know how friction blisters are generated. This will also help with blisters prevention when we do our daily exercise.

When two objects are in contact, there is bound to be friction on the contact surface, which we call shear force. This shear force is then associated with pressure and affects the structure of our skin and soft tissue.

There are two manifestations of friction blisters, internal and external. Specifically, we take the heel as an example to express.

1. When the foot wears inappropriate shoes, the skin on the heel surface rubs against the edge of the shoe, pulling the epidermal cells and tissue, causing damage to the skin surface according to the intensity and duration of the pulling.

2. When the foot wears too tight shoes, the soft tissue on the heel surface forms a strong pressure with the shoes, resulting in a large friction force, so that the soft tissue and the shoes maintain a fixed state, and the heel bone moves back and forth to pull the inner cells and soft tissue back and forth. , depending on the intensity and duration of the pull, causing damage to the soft tissue to form blisters.

When using a dressing, one is to prevent other external substances from rubbing against the skin, and the other is to effectively keep the protective position cool and dry. The smooth application makes it easier to slide between the epidermis and the external material to reduce friction, while allowing the skin and the heel bone to move more synchronously.

This is the effective blister prevention and protection brought by the smooth surface, breathable, strong adhesiveness and waterproofness of the hydrocolloid blister plaster, and at the same time. If the wound is damaged, use hydrocolloid bandage can heal.
