The skin is our largest organ. It gives us the ability to sense touch, pressure, tension and temperature differences. The receptors that are important for these sensations are located in the epidermis and dermis. Overall, the skin consists of three layers, which are interconnected.
Epidermis, dermis, subcutaneous tissue
The epidermis or epidermis is the outermost layer of the skin. It follows the dermis with the underlying subcutaneous tissue. These three layers are in turn made up of several layers. However, the sense organ skin with its complex structure should not just be considered a mere shell. Our skin serves as extensive protection, for example
- from cold and heat
- against the ingress of microorganisms
- before the loss of water and heat
- against pressure, shocks and friction
The shoe pushes!
Most skin blisters are caused by mechanical stimuli. The trigger may be, for example, the new shoes that have not yet "run in" and press, or garments that rub. The main place for bubbles is the foot. Constant pressure on a spot lifts the epidermis. The result is a cavity that fills with lymph fluid. This cushion, as painful as it may be, shields the underlying, sensitive skin layers, providing natural protection!
Help with blisters
Once the bubbles are there, special blister patches from the pharmacy help. These reduce the pressure on the bladder by their gelatinous filling and thus promote the healing process. If you puncture the bladder, be sure to disinfect the needle and bladder surface and not peel off the upper bladder skin. An open bladder can quickly inflame and further complications can result.
