Non-ablative 1550 nm fractional laser therapy not effective for erythema dyschromicum perstans and postinflammatory hyperpigmentation: a pilot study

Abstract

With these specific laser settings, non-ablative FLT was not effective for the treatment of erythema dyschromicum perstans and PIH.

Improvement of erythema dyschromicum perstans using a combination of the 1,550‐nm erbium‐doped fractionated laser and topical tacrolimus ointment

“…It is curious that early trials with Q‐switched ruby laser and FP have shown little‐to‐no improvement in cases of EDP . Though our success in treating EDP with a combination of FP and topical tacrolimus is limited to this case, the improvement seen is consistent with the results we have seen in treating other forms of hyperpigmentation .…”

“…Topical therapies, such as hydroquinone, topical corticosteroids, and tretinoin have shown limited utility . Moreover, limited trials with Q‐switched ruby and nonablative fractional laser therapy have proven unsuccessful thus far .…”

Ashy dermatosis: A comprehensive review

“…Non-ablative 1550 nm fractional laser therapy was not considered to be effective for the treatment of erythema dyschromicum perstans [30]. Moreover, the therapy resulted in postinflammatory hyperpigmentation secondary to laser burns.…”

Formation of Fibrosis After Nonablative and Ablative Fractional Laser Therapy

“…6,7 Eighteen patients with ashy dermatosis (AD; n = 6), postinflammatory hyperpigmentation (PIH; n = 4), and Becker's nevus (BN; n = 8) were enrolled in this study. Patients, materials, methods, and results have been described extensively in two previous studies.…”

“…Patients, materials, methods, and results have been described extensively in two previous studies. 6,7 Eighteen patients with ashy dermatosis (AD; n = 6), postinflammatory hyperpigmentation (PIH; n = 4), and Becker's nevus (BN; n = 8) were enrolled in this study. The local medical ethics committee approved the study protocol.…”
