Safety and Efficacy of Infrared Diode Laser on Improvement of Scar and Prevention of Recurrence of Excised Keloid

Effect of Infra-red Diode Laser on Improvement of Surgical Scar and on the Prevention of Excised Keloids Recurrence-Pilot Study

A pilot study will be conducted on 2 type of subjects, one with plastic surgery scar with a randomization of laser treated portions, and other with keloid excision scar with a complete laser treatment. The aim is to evaluate the infra-red diode laser influence on keloid recurrence and scar prevention. The keloid recurrence rate will be evaluated at each visit, and the scar prevention in plastic surgery will be evaluated comparing laser treated portion and non-treated portion.

Inclusion Criteria:

• 18 years and older
• Skin type from I to VI (Fitzpatrick classification scale)
• Scar longer than 4cm for plastic surgery's patients OR scar longer than 2cm for keloid patients

Exclusion Criteria:

• Malignant tumor pathology
• Infectious or viral skin disease
• Immunosuppressive pathology and/or immunosuppressive treatment,
• Long-term corticosteroid treatment
• Pregnant woman
