Grifola Frondosa Mycelium Ferment Filtrate Extract

Grifola Frondosa Mycelium Ferment Filtrate Extract is derived from the mycelium (root structure) of the maitake mushroom, which is fermented and then filtered to create a concentrated extract. This ingredient has been used in traditional medicine for centuries, particularly in Asian skincare practices.In skincare formulations, this extract functions primarily as an antioxidant and humectant. The fermentation process breaks down the mushroom's cell walls, making beneficial compounds more bioavailable to the skin. These compounds help neutralise free radicals and support the skin's natural mo…

The fermented extract contains polysaccharides and other bioactive compounds that work on two levels. As an antioxidant, it neutralises free radicals that can accelerate skin ageing and inflammation. As a humectant, it draws moisture from the environment and deeper skin layers into the epidermis, helping to improve hydration levels.The fermentation process is key to its efficacy: it makes the mushroom's beneficial compounds smaller and more easily absorbed by the skin, compared to using the whole mushroom material.

This ingredient works well in serums, essences and lightweight moisturisers. It pairs effectively with other hydrating ingredients like hyaluronic acid or glycerin, and complements other antioxidants such as niacinamide. There is no specific restriction on how often it can be used; most formulations containing this extract are suitable for daily use morning and evening.

Generally well-tolerated by most skin types. Those with mushroom allergies should avoid products containing this ingredient, as cross-reactivity is possible.
