What Is 40% Hydrogen Peroxide Used For?

While most people are familiar with the standard 3% hydrogen peroxide found in drugstore bottles—used for cleaning minor cuts—40% hydrogen peroxide is a much more potent formulation, strictly intended for medical use under supervision. One of the most notable applications is Eskata™, the first FDA-approved topical treatment specifically for seborrheic keratoses (SKs).

Seborrheic keratoses are non-cancerous skin growths that often appear with age. Though harmless, they can be itchy, unsightly, or easily irritated, prompting people to seek removal. Eskata™, also known as HP40, is a high-concentration, stabilized hydrogen peroxide solution delivered via a single-use applicator pen. Applied directly to the lesions by a healthcare provider, it works by breaking down into oxygen and water, triggering a reaction that selectively targets abnormal skin cells.

Approved by the U.S. FDA in February 2020, Eskata™ marked a shift in dermatology by offering a non-surgical, office-based treatment option. Clinical studies showed visible improvement in SKs after just a few applications, though multiple treatments are typically needed. It’s important to note that 40% hydrogen peroxide is not for home use—its strength can cause skin irritation, burns, or scarring if misapplied.

Unlike over-the-counter remedies or DIY treatments, Eskata™ is administered under medical guidance, ensuring safety and precision. While other methods like cryotherapy or laser removal remain common, HP40 offers a targeted alternative for patients seeking a non-invasive solution.

In short, 40% hydrogen peroxide isn’t your average antiseptic—it’s a powerful, FDA-cleared tool in the dermatologist’s toolkit, specifically designed to treat benign but bothersome skin growths with minimal downtime.
