The weakest layer of skin is the epidermis. This is the outermost layer of skin and is responsible for protecting us from the environment. Although it is the thinnest layer, it is crucial for our overall health.
The epidermis has five distinct layers:
- Stratum corneum: This is the outermost layer, composed of dead cells and keratin, which helps to protect the skin from water loss and infection.
- Stratum lucidum: This layer is only found in thick skin on the palms of hands and soles of feet.
- Stratum granulosum: This layer contains cells that produce keratin and lipids, which help to waterproof the skin.
- Stratum spinosum: This layer contains cells that help to give the skin its strength and elasticity.
- Stratum basale: This is the innermost layer of the epidermis, containing stem cells that constantly regenerate the skin.
The epidermis is constantly being shed and renewed, which is why it can be easily damaged. However, it plays a vital role in protecting us from the elements.
