Dear Scar are the fibrous tissue form on the skin in order to repair broken tissue. When there is an injury the skin produces more cells in order to grow the punctured skin that is known as scar. Scars always occur when the outer layer of the skin, the epidermis is cut and the injury extends to the dermis. The resulting scar does not have good blood circulation, is sometimes uneven and is less elastic. In addition, major variations in color are possible. Visit us at www.Malhotraayurveda.Com
