Corthellus Shiitake Extract

Shiitake mushroom extract is derived from Lentinula edodes, a culinary mushroom rich in polysaccharides, phenolic compounds, and β-glucans. These bioactive components are what give the extract its potential value in skincare formulations.In topical products, shiitake extract functions primarily as a skin protectant, working to support the skin's natural defences against environmental stressors.

Shiitake extract exerts its effects through multiple pathways. The polysaccharides and phenolic compounds present act as antioxidants, reducing oxidative damage caused by environmental factors. The extract also shows activity against elastase and collagenase — enzymes responsible for breaking down structural proteins in skin — which may help maintain skin firmness and resilience.The β-glucans further support skin health by reinforcing barrier function and enhancing the skin's protective capacity against external irritants.

Shiitake extract is typically incorporated into creams, serums, and essences at concentrations determined by the formulation. There is no specific guidance on usage frequency, as this depends on the broader product formulation and your individual skin tolerance. Use as directed on the product label.

Shiitake extract appears to be well-tolerated in topical skincare applications. However, individuals with known mushroom allergies or sensitivities should exercise caution, as shiitake can occasionally trigger allergic responses in sensitive populations.
