Biologic and synthetic skin substitutes: An overview

Area of Science:

• Regenerative Medicine
• Biomaterials Science
• Wound Healing Research

Background:

• Burn wound care is evolving towards a holistic approach, emphasizing long-term form, function, and patient quality of life.
• This shift necessitates innovative solutions like skin substitutes for managing acute burns and post-burn reconstructions.
• Current management strategies for deep dermal and full-thickness wounds face limitations, with no universally ideal skin substitute available.

Purpose of the Study:

• To review the current landscape of skin substitutes in burn wound management.
• To compare the characteristics, advantages, and disadvantages of biological and synthetic skin substitutes.
• To highlight the ongoing pursuit of an ideal skin substitute for effective, scar-free wound healing.

Main Methods:

• Literature review and synthesis of existing research on skin substitutes.
• Categorization of skin substitutes into biological and synthetic classes.
• Analysis of the structural and functional properties of each class.

Main Results:

• Skin substitutes are crucial for treating deep dermal and full-thickness wounds.
• Biological skin substitutes offer intact extracellular matrix and promote re-epithelialization.
• Synthetic skin substitutes provide controlled scaffold composition and on-demand synthesis.

Conclusions:

• Both biological and synthetic skin substitutes have distinct advantages and disadvantages.
• The development of an ideal skin substitute remains a key objective in burn care.
• Future research aims to combine the benefits of both types for optimal scar-free wound healing.
