What is a fissure?

A fissure is specifically defined as a crack or split in the skin that extends into the dermis. This type of skin lesion can result from conditions such as dryness, irritation, or underlying health issues. The significance of a fissure lies in its depth and the discomfort it can cause due to the exposure of deeper layers of skin, which may be more sensitive and susceptible to infection. Understanding the nature of a fissure is essential for estheticians, as it can influence treatment options for clients and help to assess skin health effectively.
