Abstract

Wound injuries that penetrate the deeper layers of the skin can result in scars of varying colors, textures, and sizes depending on the severity of the wound and other factors like infection and genetics.1 Although there are many types of scars, the two main scar concerns post wound healing are pigmentation and skin irritation. 2 In this review, we will cover skin physiology, how scarring occurs in the wound healing process, different types of scars, common products and treatments, and an analysis of the scar treatment market including market size, distribution, and trends. Finally, we will conclude with an overview of emerging products and tissue engineering approaches for scar treatment.
