A hypertrophic scar is a cutaneous condition characterized by deposits of excessive amounts of collagen which usually results in a raised, rigid, and red scar. Hypertrophic scars generally develop after thermal or traumatic injury which have damaged the deep layers of the dermis, they are particularly common in areas of high tension.
All scars go through a process of scar maturation, which can take up to 2 years, during this time scars can worsen (get redder, thicker and more painful) before improving. Hypertrophic scars do improve through the scar maturation process, but treatment is often needed to reduce the symptoms during this time and improve the final outcomes.
