How long will it take for skin burns to heal from an antiseptic (savlon)?

Antiseptics....: Only keep wounds clean. They are not designed to granulate tissue. The use of savlon (which contains cetrimide and chlorhexidine) will destroy active granulation skin tissues. It won't get infected, but it will take longer to heal. You are better off using saline get (hydrogels) or prescription antibiotic creams/ointments to help the healing process continue.

Fast Healing: 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.
