Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Acetic acid, commonly found in vinegar, has a documented history of use as a topical agent for mild fungal infections such as athlete’s foot (tinea pedis). The rationale for its use is based on its ability to acidify the skin surface, creating an environment less hospitable to dermatophyte fungi. Some small clinical studies and case reports suggest that soaking the affected area in a dilute (2–5%) acetic acid solution can help reduce symptoms and fungal burden, although these studies are limited in size and scope. For example, a 1992 study published in the Journal of the American Academy of Dermatology reported that acetic acid soaks were effective in managing superficial fungal infections, but emphasized that the evidence is not robust compared to standard antifungal medications.

Despite these positive indications, acetic acid is not considered first-line therapy in modern medicine. Major clinical guidelines recommend topical antifungal agents (like terbinafine or clotrimazole) as primary treatment, with acetic acid or vinegar soaks sometimes mentioned as adjunctive or home remedies, especially for mild cases or in settings where other medications are unavailable.

In summary, there is modest scientific evidence (rated 2 out of 5) supporting acetic acid’s use for athlete’s foot, primarily as an adjunctive or alternative option rather than a replacement for standard antifungal treatments.
