Explained

Undecylenic Acid is an antifungal ingredient. It is a fatty acid. However, it is not as effective as newer fungal treatments.

There are mixed reports about how effective this ingredient is for treating Malassezia folliculitis. Most products containing this ingredient are formulated for other parts of the body, such as feet.

Surviving yeast can potentially feed off the fatty acid base of this ingredient, despite it being an antifungal treatment.
