The most common sense preventive measure is to avoid or minimize wound formation, especially in individuals who are at higher risk of developing keloids. The obvious precautions are to avoid unnecessary trauma (e.g., ear piercing) and drugs associated with keloid formation. Of course many people choose to have elective surgery or cosmetic procedures (including ear piercing) and there are ways to at least minimize the risk of keloid scarring:5
Unfortunately, even careful consideration of surgical procedure is not guaranteed to prevent keloid formation. In fact, surgery is the most common cause of keloids in Caucasians.2 Extra measures should also be taken after surgery to help minimize scarring, such as massage and application of healing ointments.
