About

In this study, the investigators seek to evaluate the effects of a laser treatment on the redistribution/regeneration of collagen on the clinical, microscopic, and molecular profiles of hypertrophic scars and scleroderma.

Full description

This study is designed to evaluate the efficacy of laser treatment for the improvement of the clinical appearance of disorders of collagen metabolism, including hypertrophic scars and scleroderma. The investigators will be performing a prospective cohort study. The entire lesion will receive laser treatment only.

The investigators plan to have 20 patients (10 patients with hypertrophic scars and 10 patients with scleroderma) complete the study.

Subjects must be equal to greater than 18 years old, but may be any gender or Fitzpatrick skin type. They must have one of the following: at least one extragenital hypertrophic scar, or at least one extragenital area of scleroderma . Subjects must not have received any prescription or in-clinic medications or treatments, such as intralesional corticosteroids or excision, on the eligible scars/scleroderma in the previous 3 months. Those on anti-inflammatory or immunosuppressive medications will also be excluded.

Enrollment: 6 patients

Sex: All

Ages: 18+ years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

1. Subject must be able and willing to provide written informed consent and comply with the requirements of the study protocol;
2. In good general health, based on answers provided during the screening visit;
3. Subject must be able to read and understand English;
4. Any gender and any Fitzpatrick skin type;
5. Age equal to or greater than 18 years old;
6. Subjects in the hypertrophic scar branch must have at least one extragenital hypertrophic scar (defined as abnormal proliferation of scar tissue that forms at the site of cutaneous injury and does not regress and grows beyond the original margins of the scar) large enough to treat for both the control and experimental arm (at least 4cm in length for spit scar treatment) or two similar hypertrophic scars (at least 4cm2 for each);
7. Subjects in the scleroderma branch must have eligible extragenital lesions; large enough to treat for both the control and experimental arm or two similar scleroderma areas (at least 4cm2 area for each);

Exclusion criteria

1. Participation in another investigational drug or device clinical trial in the past 30 days;
2. Are pregnant or lactating;
3. Use of any prescription or in-clinic medications or treatments, such as intralesional corticosteroids or excision, on the eligible scars/scleroderma in the previous 3 months;
4. History of allergic reaction to topical or local anesthesia;
5. Regular intake of high doses of anti-inflammatory drugs (aspirin >81 mg/day, ibuprofen, corticosteroids, etc.) or immunosuppressive drugs;
6. Clinically significant abnormal findings or conditions which might, in the opinion of the Investigator, interfere with study evaluations or pose a risk to subject safety during the study.
