Cicatrices are scars that form on the skin after a wound or injury has healed. They are usually permanent and can be raised, discolored, or pitted. Cicatrices can be caused by a variety of things, including surgery, burns, cuts, and acne. They can also be caused by certain diseases, such as chickenpox. Cicatrices are often seen as a reminder of a past injury or trauma, and can be a source of emotional distress for some people.
