Keloids are manifested as scars growing outward after the wound heals, protruding from the skin surface and becoming hard. , there may also be a feeling of redness and pain, but after it grows to a certain extent, it will no longer continue to expand. There is a difference between scar constitution and keloids. People with scar constitution can have unlimited growth of scars like keloids after injury to any part of their body.

Although the microscopic structures of the skin and cornea are called different names, scarred constitution has its genes. The control is consistent. If even a little bit of excess tissue grows after laser surgery, it will have a serious impact on vision, so it is still listed as a contraindication for surgery.

Keloid scars are the product of excessive proliferation of fibrous connective tissue. If the epidermis of a person with a scar constitution is damaged, such as trauma, insect bites, vaccination injections, burns, folliculitis, acne, etc., there will be a serious risk. Keloid scars may form. Local factors include post-traumatic inflammation, foreign body stimulation, excessive tension, etc. Keloids protrude from the skin and appear as tumor-like proliferations.
