Functional and molecular insights in topical wound healing by ascorbic acid.

The skin acts as a vital barrier against external threats and regulates moisture levels. The skin's repair and rejuvenation encompass complex molecular and cellular mechanisms, constituting an essential yet intricate process to preserve skin integrity following trauma or surgical intervention. Acute wound repair unfolds through different interrelated stages, whereas chronic wounds pose significant healthcare challenges, often linked to conditions like diabetes and vascular diseases. Understanding of wound physiology is crucial for developing effective treatments. Chronic wounds require more comprehensive treatments, including surgical debridement, glycemic control, and antibiotic therapy. Ascorbic acid (AA) emerges as a promising wound-healing agent because it facilitates collagen synthesis, enhances antioxidant defense, promotes re-epithelialization and angiogenesis, regulates pH, and exhibits antimicrobial properties. Research outcomes on applying AA-based formulations on wound environment demonstrated its potential to accelerate wound closure and tissue regeneration, offering hope for improved wound management and reduced healthcare burdens associated with chronic wounds. The application of AA, which often utilizes innovative delivery methods and synergistic combinations with other actives, shows promise in preclinical studies for superior efficacy, biocompatibility, and controlled release profiles. Overall, AA-based therapies represent a significant avenue for advancing wound care and addressing the challenges of chronic wounds in healthcare systems.
