This depends on a number of factors, including size of wound, location of wound, your age, other issues such as medications, and diet. Often, when a wound is left to heal after skin growth removal, it will seem to not do much at all for the first 1-2 weeks. A ‘scab’ may form, but no obvious shrinkage in wound may be seen. At around 3-4 weeks the wound usually starts to heal in. The scab will peel away, with a healed area underneath. Occasionally it can take longer, but most wounds will be healed by around 5-6 weeks.
