Hypertrophic scar and keloid treatment

In older medical textbooks, the terms “hypertrophic scar” and “keloid” were often used interchangeably. Today, however, it is known that they are two different types of abnormal skin healing.

A hypertrophic scar usually develops shortly after an injury or procedure. It is pink, raised, and thickened, but remains within the boundaries of the original wound. It contains fewer abnormal blood vessels and, over time, may fade and partially flatten on its own.

A keloid, on the other hand, may develop long after the wound has healed. It is more heavily supplied with blood vessels and has a tendency to grow beyond the borders of the original skin injury, extending into healthy tissue. Without treatment, a keloid usually does not go away and may continue to grow to an unpredictable size.

Complete removal of a hypertrophic scar or keloid is not always possible. The main aim of treatment is to flatten and soften the scar, reduce redness, and relieve symptoms such as itching, pain, and tightness. Treatment is also designed to stop the scar from continuing to grow. In many cases, it can lead to a significant improvement in both appearance and overall comfort.

Treatment for hypertrophic scars and keloids usually requires a series of 3 to 6 sessions performed approximately every 4 weeks. The exact treatment plan is determined individually during the consultation and depends on the type, size, location, and age of the scar.

The first results – such as a flatter scar, reduced redness, and less itching – are often noticeable around 2 weeks after the first treatment. However, the full improvement usually requires a series of treatments.

The treatment usually causes only mild discomfort. Most patients experience a brief stinging, burning sensation, or a feeling of pressure at the injection site. These symptoms typically subside quickly once the injection is complete.

Yes – Caesarean section scars are one of the most common reasons for treatment. Therapy can usually begin once breastfeeding has ended and the scar has stabilised. During the consultation, the doctor will assess whether the tissue is ready for treatment and then recommend the most suitable method.
