While many people use Betadine (povidone-iodine) as a go-to for minor cuts, experts agree that applying it to open, healing wounds is not recommended. The reason you shouldn't use Betadine on open wounds is that its harsh properties can damage the very cells needed for a swift and complete healing process.

Many common antiseptics like hydrogen peroxide are cytotoxic to cells crucial for wound repair, potentially delaying the healing process. For minor cuts and scrapes, this is **why shouldn't you use antiseptic** products, as gentle cleaning with soap and water is often safer and more effective.

Many common antiseptics are toxic to human cells, not just microbes [1.2.1]. This fundamental cytotoxicity is the primary reason behind the critical question: Why can't antiseptics be used inside the body? Their non-selective nature causes significant harm internally.

While antiseptics are valuable for preventing infection on minor cuts and scrapes, studies indicate that applying them to certain types of wounds can impede the natural healing process. Knowing where should we avoid using antiseptics is critical for administering proper first aid and ensuring safe medical care.

Chronic wounds affect approximately 6.5 million people in the US each year [1.10.2]. While hydrogen peroxide was a staple in first-aid for generations, many now wonder why don't hospitals use peroxide for modern wound care, a shift driven by a deeper understanding of the healing process.

In chronic toxicity testing, the IC25 is a critical statistical calculation used to determine the concentration of a substance that causes a 25% reduction in a biological function like growth or reproduction [1.2.1, 1.2.2]. Understanding **what is IC25 toxicity** is fundamental in pharmacology and environmental science for assessing the subtle, long-term effects of chemicals.

Despite its long history as a household staple, evidence shows that using hydrogen peroxide on wounds can damage healthy tissue and delay healing. While the fizzing action was once seen as a sign of effective cleaning, medical experts now recommend safer and more effective alternatives for proper wound care.
