Hypertrophic Scar / Keloid Treatment

Hypertrophic Scar / Keloid Treatment

Keloid and Hypertrophic scars are fibro-proliferative disorders of the skin that are caused by abnormal healing of the injured or irritated skin such as trauma, burn, surgery, vaccination, skin piercing, acne, and herpes zoster. 

Keloid scars are raised, round or oval with regular margins and some with irregular margins have a crab claw-like look. Keloids are firm with a smooth surface and extend beyond the edges of an original wound or trauma. Keloids can occur anywhere on the body but occur more commonly over the face (low part), neck, ears, chest, shoulders, upper arm. They are often associated with itching, pain, anxiety or depression, and disruption of daily activities.

Hypertrophic scars are similar, slightly smaller than keloid, develop directly at a wound site, and do not go beyond the bounds of injury. They are often raised, red, and regress over time. 

Keloids & Hypertrophic scars both are raised to have a heaped-up appearance. These scars rise above the rest of the skin; keloid remain elevated above 4mm to the skin surface

DO’s and Don’ts as a preventive measure in keloid with higher risk groups:

Do consult the expert skin professional treating the same.
Do not expose to sun
Do use a broad spectrum sunscreen daily
Do not go for ear or body piercing and tattoos
Do use a protective clothing on outdoor to protect the scar
Don’t pop pimples
Do be careful while shaving to prevent nicks and cuts
Do not scrub or scratch your skin too roughly
Do treat the injuries and burns immediately
Do not ignore at initial stage of formation
Do take care if you have acne and maintain a proper skincare regimen
Do not go for cosmetic surgery, if family or in personal have keliod tendency
Do massage the scar
Do not smoke, as it decreases blood circulation in the skin and inadequate wound healing and possibly tissue loss
Do keep the wound moisturized
Do not have un-realistic expectations from the treatment


The treatments for Keloid and hypertrophic scars are similar, but hypertrophic scars have a better prognosis with age. Hypertrophic scars can easily be treated however keloids are resistant to treatment. Treatment is based upon the depth, size, and location of keloid. History of previous treatment and its response is important before starting the treatment.

There are different treatments available are mentioned below:

Any physically healthy, mature, and realistic expectations with a desire to reduce or remove a keloid scar is an ideal person. 

Medical treatments: 

The two most common and effective treatments are:

Topical Silicone gel or creams or sheets are useful to some extent.

Intralesional steroid or 5FU or verapamil injections are often used to stop the growth of keloids. Injecting long-acting cortisone (steroid) into the keloid once a month is the most effective first-hand treatment. 

Other medical options include:

Retinoic acid, Interferon (IFN) therapy, doxorubicin, bleomycin, imiquimod 5% cream, tamoxifen, and tacrolimus

Antiangiogenic factors, including vascular endothelial growth factor (VEGF) inhibitors (eg, bevacizumab),

Photodynamic therapy, UVA-1 therapy, transforming growth factor (TGF)–beta inhibitors, tumor necrosis factor (TNF)-etanercept, which are all directed at decreasing collagen synthesis.

Compression therapy or Pressure garments it suppresses collagen production.                                                                                         

Occlusive scar dressings should be worn for at least two to three months and can be extended as per requirement.

Treat secondary infection in time, drain the abscess and sinus, and remove coiled hair inside the keloid.

Cryosurgery: most commonly used for small or limited keloids, most suitable and is often used parallel to steroid injections.

Laser or Energy-based treatment

Laser therapy:very good at improving skin texture and color, and in combination with other treatments flatten out the keloid.

Pulsed Dye Laser: most effective if used early and in combination with other techniques. The principal effect of a pulsed dye laser is on scar microvasculature, reducing erythema and pruritus, and improving skin texture and significant improvement in the scar. 

Fractional Co2 creates deep channels into thick scar tissue with debulking mode; and if used in combination collagen remodeling agents can almost flatten the hypertrophic scar and keloids, if used for few consecutive months.

Laser hair removal: hair follicle and sebum production act as a trigger; hence laser hair removal can be added

Fractional MNRF and individual radiofrequency devices in combination with cryo and intralesional steroids give excellent results.

Enerjet: Hyaluronic acid (HA) is a glycosaminoglycan that plays an important role in the reorganization of the extracellular matrix (ECM) during the skin wound healing process. Decreased presence of HA is a major characteristic of keloid and hypertrophic scarring

Enerjet uses Jet Volumetric Remodeling (JVR) technology a high-pressure jet technology to laterally introduce healing agents deep into the dermal layer of the skin for the reduction of keloid.

Surgical excision: Surgical Removal is can be done for larger, more extensive, and especially over the ears. The technique involved may employ a scalpel, radiofrequency device, or CO2 laser removal. It’s better to avoid surgical excision as it may result in a new keloid, and even larger than the original one.

Radiation therapy: carried out soon after surgery
