Cracks in the skin that penetrate the dermis layer are called?

Fissures refer to cracks or splits in the skin that extend into the dermis layer. When the skin experiences tension, dryness, or irritation, it can lead to this condition, creating a narrow opening that can be quite painful and may become a site for infection if not properly cared for.

Ulcers are usually deeper lesions that can involve tissue loss and are often associated with underlying health issues. Scales are dry, flake-like patches of skin that may accumulate on the surface but do not penetrate the dermis. Blisters are fluid-filled sacs that appear on the skin's surface due to friction, burns, or other injuries, and typically do not extend into the dermis but rather are confined to the epidermal layer. Understanding these distinctions is crucial for proper assessment and treatment of skin conditions in esthetics.
