Hypertrophic scars are thick, broad, and frequently elevated marks that develop at sites of skin injury. Treatment approaches range from clinical procedures performed by medical professionals to at-home care methods, with the choice depending on how quickly you wish to reduce their appearance.

Understanding Hypertrophic Scars
Hypertrophic scars are dense, wide, and often elevated tissue formations that appear following skin trauma. While scarring is a normal healing response, hypertrophic scars represent an irregular reaction to injury.
Some individuals, based on skin characteristics or healing patterns, may generate excessive collagen during wound recovery. Contributing factors include infections, inflammation, wound tension, or leaving injuries unclosed, all of which can stimulate collagen overproduction and hypertrophic scar development.
These scars frequently emerge after burns but may also result from piercings, lacerations, or acne. Though resembling keloid scars, hypertrophic scars typically stay confined to the initial injury site.
While not medically dangerous, hypertrophic scars can cause itching, discomfort, or aesthetic concerns. Various treatments exist, including topical applications, silicone dressings, steroid injections, or laser procedures to minimize scar visibility and symptoms.
Hypertrophic Scar Treatment Options
Medical professionals may recommend multiple approaches to flatten and diminish scar appearance.
It’s important to recognize that scar maturation is a gradual process—potentially lasting a year. During this time, your body naturally refines scar tissue. Consequently, physicians often recommend observing early hypertrophic scars for several months to a year before beginning treatment.
Clinical Treatment Methods
Corticosteroid therapy: Steroid injections serve as a frontline treatment for hypertrophic scars. Administered every six weeks, these injections can flatten and soften scars, though usage is limited due to potential tissue weakening.
Laser treatment: Most effective for recent scars, laser therapy burns and flattens raised scars while addressing pigmentation to lighten their appearance.
Bleomycin injections: Direct scar injections of Bleomycin show potential for improving appearance and alleviating symptoms like itching and pain, though additional research is required.
Cryotherapy: Liquid nitrogen freezing can successfully flatten hypertrophic scars, with studies demonstrating its safety and patient tolerance.
Surgical removal: After allowing at least one year for scar maturation, surgical excision with proper wound closure can eliminate hypertrophic scars while addressing contributing factors like infection or tension.
At-Home Treatment Approaches
Silicone products: Silicone sheets represent a noninvasive, commonly recommended treatment. Available as sheets, gels, sprays, or foams, they’re applied daily for several hours over multiple months.
Pressure therapy and massage: Cost-effective scar management involves applying pressure and massaging the area. Using bandages or tape can gradually soften scar tissue and enhance appearance.
Onion extract products: Over-the-counter gels containing onion extract (like Mederma) exist, though clinical evidence supporting their efficacy for hypertrophic scars remains limited.
Bio Oil: While popular for scar treatment, Bio Oil requires more extensive clinical testing to confirm its effectiveness for hypertrophic scars. It’s widely available at cosmetic retailers.

Distinguishing Hypertrophic from Keloid Scars
Before treating a hypertrophic scar, proper differentiation from keloid scars is essential, as treatment strategies differ. Keloids are firm, smooth, benign growths resulting from excessive scar tissue proliferation.
Hypertrophic scars generally:
- Raise less than 4 millimeters above skin level
- Appear red or pink
- Can form anywhere on the body
Keloids typically:
- Extend more than 4 millimeters above skin
- Grow beyond original wound borders
- Display pink to purple coloring
- Progressively enlarge
- Commonly appear on earlobes, shoulders, cheeks, and upper chest
Both scar types occur more frequently in darker skin tones. While hypertrophic scars respond better to treatment, keloids often reappear despite intervention.
Preventing Hypertrophic Scarring
Following injuries, particularly burns or surgical procedures, these measures may help prevent hypertrophic scarring:
- Maintain proper wound hygiene and use dressings to prevent infection
- Apply silicone sheets post-surgery, shown effective in scar prevention
- Consult your doctor about post-operative steroid injections to minimize scarring
Preliminary research indicates that immediate burn cooling with cold compresses and tea tree oil application might promote improved healing and potentially prevent hypertrophic scars, though further studies are necessary.
