Our take
Is Inonotus Obliquus (Mushroom) Extract a Good Ingredient?
Rated Fair because its antioxidant potential is plausible, but topical evidence and standardization are limited, so results may be modest. As a fungal extract, sensitization is possible, especially for those with mushroom allergies, which is enough to hold the rating at Fair.
