How Does Psoriasis Work?
Skin is an organ on its own and is part of a large organ system called the integumentary system, which also includes oil glands, sweat glands, hair and nails.
There are two main layers of skin: the epidermis and the dermis.
- The dermis is the bottom layer and the epidermis is the outer layer of skin.
- The deepest layer produces millions of new cells every day. The cells are pushed up toward the surface of the skin.
- Typical skin cells regenerate every 28 days; for psoriasis patients, skin cells are regenerated in 3-7 days.
- This leads to cells piling up before the body can have time to shed them, forming red, sore, scaly plaques on the affected areas.
