Abstract
Reishi mushroom (Ganoderma lucidum) is a unique medicinal mushroom that has been used for the treatment of various diseases in Asian countries for more than 4 thousand years. Today, this mushroom is also used in treatments related to traditional medicine. In addition to its diverse biological properties, its positive effects in improving the quality of the skin and treating skin diseases have attracted the attention of researchers. Polysaccharides and triterpenes are among the most important and effective metabolites of this mushroom, which are important in skin treatment and health due to their antioxidant and anti-inflammatory functions. This review summarizes the latest research achievements on the role of this mushroom in skin health and treatment. A number of studies have shown that the extracts of Reishi mushroom can accelerate wound healing, relieve post-burn infections, and prevent skin flaps due to ischemia (re-perfusion) damage. The effect of Reishi mushroom extracts on the prevention and treatment of wrinkles and the effect on skin whitening has made them a natural ingredient for skin care. Also, studies conducted on the effects of Reishi mushroom in the treatment of some skin diseases such as atopic dermatitis (eczema), cutaneous sarcoidosis, and the potential use of this mushroom in the treatment of skin cancer have been discussed.

Abstract
Worldwide, 16,000 deaths occur daily due to wound injuries, leading to increased concern in low- and middle-income countries. Today, with the increasing demand of consumers to use natural biological compounds instead of using harmful and carcinogenic chemical compounds, algae were introduced to the market as an effective clinical skin alternative. In fact, ease of cultivation and low nutritional requirements make algal polysaccharides an attractive alternative for advanced wound dressings. Micro and macroalgae are a new source of biological saccharide polymers for wound healing. The hydrophilic nature of these polymers due to their capacity to trap water molecules in their structure makes hydrogels that have a high ability to absorb and release liquid. In this review article, by studying the latest articles, some algae polysaccharides that are widely used as wound healing dressings such as alginates, fucoidans, carrageenans, laminarin, agar-agar and olvan are discussed. These compounds are not only used as functional biomaterials for controlled drug delivery, but also for cell stabilization and preparation of scaffolds for tissue engineering.

Abstract
Bacteria are natural sources of metabolites that exhibit diverse bioactive properties, including wound healing, antioxidative, antibacterial, antifungal, anti-inflammatory, antidiabetic, and anticancer activities. Two important groups of bacteria with wound healing potential are polysaccharides and peptides. In addition to cellulose, bacteria produce various polysaccharides (such as exopolysaccharides) with wound healing potential. The most common bacterial peptides used in wound healing studies are bacteriocins and lipopeptides. The aim of this article is to review recent literature on the potential of wound healing in vitro and in vivo by polysaccharides and peptides derived from bacteria (Actinobacteria, Bacteroides, Cyanobacteria, Firmicutes, and Proteobacteria). For this reason, a search was conducted in scientific research databases such as Web of Science, Google Scholar, Wiley, Elsevier, Taylor and Francis, BMC Springer and MDPI with the keywords polysaccharide, peptide, bacteriocins, lipopeptides, streptomyces, bacteria, lactic acid bacteria, cyanobacteria and wound healing. The overall results showed that polysaccharides and peptides and peptides derived from bacteria show wound healing power both in vitro and in vivo. In living models, including animals and humans, these metabolites have a positive effect on wound healing by inhibiting pathogens, antioxidant activity, modulating the inflammatory response, moisturizing the wound environment, promoting the proliferation and migration of fibroblasts and keratinocytes, increasing collagen synthesis, remodeling, epithelialization and angiogenesis. Therefore, peptides and polysaccharides derived from bacteria play a significant role in wound healing.
