Can a chemical like peroxide touch a wound?

Perioxide. Wound care experts do not like the use of hydrogen peroxide in a wound since the chemical can kill good cells along with its 'cleansing' activity. Keep it away from your wounds and seek help from your clinician.
Real Answer. The real question is what not to do that slows down healing. Avoid using alcohol, peroxide, hibiclens, betadine, and bleach solutions. Inflammation ( red, hot, swollen, tender) is important to healing so anti-inflammatories (motrin, advil) are bad. Cover the area with a clean dressing changed every other day and protected from trauma. Antibiotics do not help healing unless it is truly infected.
