Keloid Scars
Keloid scars are raised, thickened scars that grow beyond the boundary of the original wound. Unlike normal scars, they continue to enlarge over time and may cause pain, itching, or cosmetic concern. Keloid scars are more common in younger people, darker skin types, and can form after acne, piercings, surgery, trauma, or burns. At DermLab, our Dermatologists in Hamilton, Waikato specialise in Keloid scar management, offering safe, evidence-based treatments tailored to each patient.
What They Can Cause
Raised, thick, or expanding scar tissue
Discomfort or itching
Cosmetic concerns affecting confidence

Treatment at DermLab
Corticosteroid injections – to soften and flatten keloids over time
Surgical removal – carefully performed by Dermatologist surgeons, usually combined with other therapies to reduce recurrence risk
Laser therapy – CO₂ laser or vascular laser to improve texture, redness, and thickness
Cryotherapy – targeted freezing to shrink smaller keloids
Silicone gels and dressings – non-invasive topical options to improve scar texture and reduce itch
Combination therapy – often the most effective approach, e.g. surgery plus steroid injections plus silicone aftercare
