How to prevent scarring on wounds, what is the best method?

In general, there is no such thing as a single "best method for preventing scars on wounds." However, minimizing scarring can be achieved through proper wound care—such as timely disinfection using iodophor or normal saline—and applying sterile gauze with pressure dressing, which can help reduce scar formation. Additionally, aesthetic medical treatments like cryotherapy, microneedling therapy, and fractional laser therapy may also be considered to lower the risk of scarring.
