Abstract
The skin, our body's largest organ, comprises the epidermis, dermis, and subcutaneous tissue, playing a crucial role in protection and regulation. Beta-glucans (BG), derived from yeast by-products, exhibit cosmeceutical properties with applications in skincare. This chapter details the skin's structure and beta-glucans' molecular characteristics, emphasizing their solubility influenced by branching and polymerization. The beneficial features of BG for the skin, including antioxidant, immunomodulatory, and wound healing properties, are explored. In particular, BG's antioxidant capacity mitigates oxidative stress, while its immunomodulation aids in inflammation regulation and potential skin cancer prevention. The chapter also highlights BG's role in wound healing, tissue repair, and its anti-aging effects, demonstrating its versatility in skincare applications. Commercial products incorporating BG underscore its increasing presence in skincare formulations, aligning with consumer preferences for natural bioactive ingredients. Despite significant progress, further research is needed to explore BG's impact on complex skin systems and its potential in managing various skin conditions. The utilization of industrial by-products, such as spent yeast, as a sustainable source for BG extraction adds an eco-friendly dimension to its application in skincare formulations. Standardized extraction methods and deeper insights into BG interactions with different skin layers will contribute to unlocking its full potential in skincare.
