What are scars & why scars arise? Scars occur after healing of a wound caused by accident, burn, or surgery. Scars form on the human skin and look like fibrous tissues. Skin is a very sensitive and soft part in the human body. Scars naturally form on the wounded area when the healing process is complete. Skin problems like acne and infections like chicken pox will also leave scars on various areas of the body. Most of the wounds leave scars on the body, and the size of the scar is related to the size of the wound. The damaged area of the skin is repaired and collagen fibres are formed over the wound by the cells called fibroblasts. The fibrous tissue or scars resultant of wound do not possess the qualities of the skin. They are not resistant to ultra violet radiation and the hair follicles don’t grow on these spots. These scars cannot be removed completely from the body, but there are various treatment methods to enhance the appearance of the affected area. Types of Scars Keliod scars: These scars take a tumor like shape and bulge beyond the wounded area. These scars protrude beyond the wound, and are severe when the wounded area is around the joint. Hypertrophic scars: These are similar to keliod scars in shape, but do not protrude beyond the wounded area. Contracture scars: These type of scars form on wounds caused by burns. The skin gets tightened as a result of these scars, and one may experience difficulty to move. Acne scars: These scars are resultant of severe acne. The size and type of scars varies depending on the type of acne. Chicken pox scars: Chicken pox leaves scars on the skin after infection. These scars may be darker than the skin color and remains almost throughout life.
