LET

Concern level

High concern

Shiitake mushroom mycelium extract is a botanically derived cosmetic extract used primarily as a skin-conditioning active. It is typically composed of polysaccharides and other fungal metabolites, and is used in leave-on skincare for soothing, antioxidant, and conditioning support. CosIng lists Lentinus edodes extract as a cosmetic ingredient, and PubChem documents lentinan as a shiitake-derived polysaccharide.

Risks & Warnings

Main concerns are possible sensitivity or allergy in very reactive users and batch-to-batch compositional variability typical of extracts. Because it is a complex natural extract, exact allergen profile and actives can vary by supplier. Use caution in formulas for users with known mushroom sensitivity.
