Comparative Efficacy of Oral Tranexamic Acid, Intradermal Tranexamic Acid, and Fractional Er: YAG Laser Combined With Hydroquinone in Refractory Melasma: A Randomized Clinical Trial

Journal of Cosmetic Dermatology, Volume 25, Issue 7, July 2026.
ABSTRACT Background Refractory melasma is difficult to treat because of its chronic relapsing behavior and complex pathophysiology. Combination treatment may improve outcomes over topical depigmenting treatment alone. Objective To compare the efficacy and safety of oral tranexamic acid (TXA), fractional Er:YAG laser, and intradermal TXA, each combined ...

Heme Oxygenase‐1 Differentially Controls Pigmentation in Physiological and Pathological Melanogenesis

Pigment Cell &Melanoma Research, Volume 39, Issue 4, July 2026.
HO‐1 acts as a context‐dependent regulator of pigmentation, enhancing tyrosinase activity and melanin accumulation in melanoma cells while having no detectable effect on pigmentation in the non‐malignant melanocyte models tested. ABSTRACT Melanogenesis is a defining feature of melanocyte biology and influences melanoma pathogenesis; however, tumor ...

Comparison of Human Melanoma Single Cell Profiles to Evolutionary Medicine Model Xiphophorus Provides Insights in Disease Control

Pigment Cell &Melanoma Research, Volume 39, Issue 4, July 2026.
Single‐nucleus RNA sequencing analysis of Xiphophorus melanoma, an evolutionary medicine model, revealed cellular heterogeneity that closely mirrors that of human melanoma. Immune and tumor cell subtyping identified an immune‐evasive tumor microenvironment. This melanoma cell atlas provides a framework for investigating conserved cellular and molecular
