Keloids Guide – Definition, Causes & Treatment

Keloids are scars that grow beyond the original borders of the wound. Like hypertrophic scars they are raised, but they are often dark in colour and hard to the touch. Without treatment, they will often continue to grow. Keloid scars can make you self-conscious, but you don’t have to live with them. Treatment can diminish the appearance of keloids or sometimes get rid of them altogether.

How Keloids Form
The cause is exactly not known. They are the result of an overactive healing response. To bridge the gap caused by skin damage, your body creates granular tissues, which are made primarily of collagen, across the injury site. Imbalance between collagen stimulators and inhibitors lead to formation of keloid. Sometimes, the fibroblasts that lay down this bed of collagen don’t get the message to turn off and continue creating the granular fibres, actually overlaying your natural skin with them.The result is a scar that continues to grow outward, often in all directions, expanding beyond the original site of the wound.

• Risk Factors:

  1. 10-30 years of age
  2. Women
  3. Individuals with darker skin
  4. People with a family history of keloids
  5. Oily and hairy areas
  6. Commonest sites: Areas of highest friction and hair growth: elbows, shoulders, lateral thighs, back of the neck, chest
  7. Poorly cared and badly healed wounds

• Complications:

  1. Recurrent infections, abscesses
  2. Additional scarring and hypertrophy

Skin City Protocol of Keloid Management:
1) Control the trigger factors:

  1. Laser hair removal: hair follicle and sebum production act as a trigger, hence laser hair removal can be added
  2. Treat infection in time, remove/ drain abscess/sinus, coiled hair inside the keloid
  3. Vascularity: to decrease the vascular supply of keloid tissue by IPL or vascular lasers

2) Collagen Suppression Therapy

  1. Steroids/ 5FU injections are often used to stop the growth of keloids. They cause the fibroblasts to stop their work, and encourage your body to remodel the scar tissue into normal skin. This will diminish and change the appearance of keloids, but rarely eliminates them entirely.
  2. Pressure garments:
    It suppresses collagen production
  3. Silicon

• Collagen Remodelling Therapy:

  1. Combination of Ultrapulse SCAAR Fx and fractional drug delivery has given wonderful results. This unique protocol developed at Skin city, PG institute of Dermatology & lasers have shown results as effective as complete clearance in most of the cases.
  2. Ultrapulse SCAAR FX is known to create deep channels into thick scar tissue with minimal lateral thermal damage. This coupled with fractional drug delivery of collagen remodelling agents can almost flatten the hypertrophic scar and keloids if used for sufficient period of time.
  3. A typical treatment protocol for keloid and hypertrophic scar management will extend from 6 months to 18 months involving monthly or bimonthly OPD based treatment sessions.
