May feed Fungal Acne
These ingredients are considered potential triggers for fungal acne, but not everyone will react to them. Because fungal acne can be tricky to identify and manage, itโs best to consult a dermatologist for an accurate diagnosis and treatment plan.
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.
