Retinol can help wounds heal faster in older people

In an exciting development, researchers at the University of Surrey, in collaboration with Phytoceutical Ltd., have unveiled a groundbreaking approach to wound healing that could transform the treatment of chronic wounds worldwide, particularly benefiting the elderly.

Their studies demonstrate that nano micelles of Retinol, a form of Vitamin A already popular in anti-aging skincare products, can significantly enhance wound healing by stimulating skin tissue regeneration.

This innovative use of Retinol not only accelerates the healing process but also offers a potent solution to one of the most challenging aspects of wound care: the battle against biofilms and key bacteria that hinder wound recovery.

Chronic wounds, which are wounds that take an extended period to heal, afflict over 1% of the global population, leading to considerable discomfort and complications for those affected.

These wounds can result from various factors, including surgery, accidents, or underlying conditions such as diabetes.

The traditional treatment methods for these wounds often fall short, particularly for deeper wounds, and the reliance on antibiotics has contributed to the growing issue of antimicrobial resistance.

The University of Surrey and Phytoceutical Ltd.’s research, detailed in their paper published in the International Journal of Pharmaceutics, focuses on the use of Retinol-based micellar formulations free from antibiotics.

By applying these formulations to organotypic skin wound models in the lab, they discovered that Retinol micelles are remarkably effective in disrupting biofilms and eliminating bacteria associated with chronic wounds, thus diminishing the need for antibiotics.

Their findings are especially promising as they offer a dual benefit: speeding up the healing process and combating antimicrobial resistance, which is a major concern in modern healthcare.

The study tested two concentrations of Retinol micelles, with the 0.3% formulation showing the most significant impact on wound healing.

This breakthrough indicates a shift towards more targeted and effective treatments for chronic wounds, reducing the likelihood of wounds becoming chronic and the associated suffering.

The next steps for the research team include larger-scale laboratory and clinical tests to further validate the efficacy of this approach.

Dr. David Oluwole, a research fellow involved in the study, highlights the importance of this discovery, noting the current lack of specificity and effectiveness in chronic wound treatments.

Dr. Lian Liu, another key researcher, emphasizes the crucial role of Retinol micelles in keeping biofilm formation at bay and promoting tissue regeneration.

As this research progresses, the potential for developing new medical products based on Retinol micelles opens up, offering hope for millions of individuals suffering from chronic wounds.

This innovative approach not only aims to alleviate pain and accelerate recovery but also aligns with the ongoing efforts to reduce reliance on antibiotics and tackle antimicrobial resistance, marking a significant advancement in wound care and treatment.
