Moreover, in 2 of the patients, CO2 laser was able to treat areas inaccessible to other methods. The reason for the efficacy of ablative methods is debated. Re-epidermization with keratinocytes of appendices and not expressing the molecular defect, and the constitution of dermal cicatricial tissue, are two currently proposed hypotheses.
