Efficacy of the Combination Therapy of Intense Pulsed Light and Microneedling With a Postbiotic Formulation for Melasma.

ABSTRACT:

Background

Melasma pathogenesis involves multifactorial mechanisms, and a comprehensive strategy achieves superior outcomes compared to monotherapy. Intense pulsed light (IPL) reduces pigmentation via selective photothermal effects, while microneedling enhances melanin clearance through mechanical stimulation and improves transdermal drug delivery. However, the therapeutic synergy of combining IPL with microneedling for melasma management requires further validation.

Objective

To assess the clinical effectiveness of combining IPL and microneedling with a postbiotic formulation containing Lactobacillus fermentation lysate in facial melasma.

Methods

Thirty individuals were enlisted and randomly split into two groups. IPL therapy group: Received IPL treatments at 4-week
