Chronic skin wounds affect more than 40 million patients globally and represent a severe growing burden for the healthcare systems, with annual costs expected to exceed $15 billions by 2022. To satisfy the huge demand for effective wound care products, different types of wound dressings have been introduced on the market during the last decades. Based on “the moist wound healing theory” postulated by Prof Winter in 1962, bandages
were initially designed to recreate the optimal wound environment to favor the healing process. Then, thanks to the advancements achieved in biomaterial design and processing, biotechnology, imaging and electronic fields, great effort has been devoted to the development of formulations able to actively participate to tissue healing.
Indeed, both the literature and the market report the design of medicated wound dressings, i.e., wound care products releasing anti-microbial agents, anti-inflammatory drugs, or bioactive molecules. In this scenario, this review aims at critically describing the currently available wound care products, highlighting their proved effectiveness in wound management. Moreover, an overview of the main strategies exploited to design personalized
wound dressings has been reported. Lastly, concerns on regulatory affairs and practical issues limiting the clinical translation of advanced research platforms have also been discussed.
The treatment of hard-to-close wounds represents a challenging issue to face due to the huge and growing incidence of this pathology in the society: only in Europe, 4 million patients suffer from chronic wounds every year. Moreover, chronic wound management is associated with
severe costs for the healthcare systems and low patients’ quality of life.
Therefore, based on the “moist wound healing theory” postulated by Prof Winter in 1962 [7], many different wound dressings have been developed during the years aimed at becoming the ideal wound dressing for chronic ulcer treatment.
