Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Boric acid has a long history of use as an antiseptic for the skin, dating back to the late 19th and early 20th centuries. Scientifically, boric acid exhibits broad-spectrum antimicrobial properties, including antifungal and antibacterial effects. Studies have demonstrated its efficacy in treating certain skin infections, such as superficial fungal infections (e.g., tinea or candidiasis), and it is still used in some topical preparations, particularly in regions with limited access to newer antifungal agents. Its mechanism of action involves disrupting the cell wall of fungi and bacteria, leading to cell death. However, its use has declined in favor of safer, more targeted agents, as boric acid can be toxic if absorbed in significant quantities through damaged skin or in infants. The evidence supporting its efficacy is moderate, with controlled trials being limited and most data coming from older literature or case series. Current guidelines generally recommend alternative treatments, but boric acid may still be considered in specific circumstances, particularly for resistant infections or when other treatments are unavailable. Overall, while there is scientific support for its use in treating some skin infections, concerns about toxicity and the availability of superior alternatives have limited its modern use.
