Hello, Welcome to healthcaremagic. From your query i understood that you are very much distressed by Keloid. Keloid is a scar tissue which extend beyond the wound margin due to increased collagen. It can develop even from minor prick or cut. It is impossible to tell who will develop a keloid. A person who has had a keloid should not undergo elective or cosmetic skin surgeries or procedures such as piercing. So keloid is better prevented by avoiding unusual procedures an injuries. You have tried both Laser and Cryotherapy. Finally only option is either chemotherapy or radiotherapy. Chemotherapy is with fluorouracil with steroids. Radiation yield better results in 90% of keloid affected persons. Hope it helps. Take care.
