Treatment can be started as soon as the wound has completely closed and healed and after sutures have been removed in the case of a surgical intervention. Clinical studies have shown positive results after 8 weeks of consecutive use of at least 12h a day. First results are noticeable after 3 to 4 weeks. Using the patch for longer than 8 weeks may further improve the appearance of the scar. Results may vary from person to person and from scar to scar.
