The concentration of the Hydrogen Peroxide solution you mentioned is 6.5% w/v, which means there are 6.5 grams of hydrogen peroxide dissolved in every 100 milliliters of solution.

This concentration is commonly used for antiseptic purposes, such as cleaning wounds, preventing infections, and treating minor skin irritations. It works by releasing oxygen that helps cleanse the affected area and kill bacteria, viruses, and fungi.

Please use it carefully, avoiding contact with eyes and not applying it on large or deep wounds. If you experience persistent irritation or have concerns about its use, it is best to consult a dermatologist or a healthcare provider for personalized advice.
