Keratinocytes exposed to ultraviolet A and ultraviolet B radiation induce responses in melanocytes

Photochemistry and Photobiology, EarlyView.
Keratinocyte‐derived soluble factors regulate melanocyte responses following UV exposure. Conditioned medium from irradiated keratinocytes enhances melanocyte mitochondrial activity, cell proliferation, and cell cycle progression while improving survival after UVA‐induced damage.

Co-Treatment with Phlorotannin and Extracellular Vesicles from Ecklonia cava Inhibits UV-Induced Melanogenesis

Antioxidants
Hyperpigmentation due to ultraviolet (UV)-induced melanogenesis causes various esthetic problems. Phlorotannin (PT) and extracellular vesicles (EVs) derived from various plants suppress melanogenesis pathways.

Understanding exosomes in facial esthetics and skin aging

Periodontology 2000, EarlyView.
Abstract Background Skin aging is a multifactorial process mediated by intrinsic (genetic and metabolic) and extrinsic (environmental) factors leading to functional and structural deterioration, including wrinkles, loss of collagen and elastin, as well as various pigmentation disorders.

CXCL1-CXCR2 axis inhibits melanogenesis through the suppression of the WNT/β-catenin pathway

Frontiers in Immunology
Abnormal skin pigmentation is a common clinical dermatological issue, and its occurrence and development are closely associated with the inflammatory microenvironment.

Understanding Exosomes in Hair Regeneration

Periodontology 2000, EarlyView.
Abstract Background Alopecia is a prevalent condition correlated with significant psychosocial challenges, while contemporary treatments exhibit variable efficacy, require extended use, and may cause adverse effects. This review aimed to comprehensively assess exosome‐mediated interventions as a novel cell‐free regenerative approach for hair ...

Ovarian hormone loss modifies the nucleic acid cargo of circulating extracellular vesicles and skeletal muscle metabolism after acute exercise in rats

Experimental Physiology, EarlyView.
Abstract Loss of ovarian hormones (i.e., menopause) leads to negative effects on metabolic health. While exercise offers significant benefits, it seems to be insufficient to completely reverse these changes. The mechanisms by which exercise conveys the effects throughout the body are still poorly understood.

Novel Postzygotic Variants Associated With Hypomelanosis of Ito Expand the ACTB‐Related Neurocutaneous Disease Spectrum

Clinical Genetics, Volume 110, Issue 3, Page 369-373, September 2026.
We describe a previously unreported phenotype related to postzygotic ACTB variants with hypomelanosis of Ito, characterized by hypopigmentation associated or not with neurodevelopmental features, distinct from Becker presentations, bridging constitutional neurodevelopmental and somatic cutaneous phenotypes.

Inonotus obliquus Extract as An Inhibitor of α-MSH-Induced Melanogenesis in B16F10 Mouse Melanoma Cells

Cosmetics, 2019
Melanogenesis is a biosynthetic pathway that produces the pigment melanin in human skin. The catalyzation of the key enzyme tyrosinase is the first step in melanogenesis, and the downregulation of tyrosinase enzyme activity is the most reported method ...

Staurosporine Drives Non‐Canonical Melanocyte Maturation by Coupling β‐Catenin Signaling to Actin‐Dependent Dendrite Remodeling

Pigment Cell &Melanoma Research, Volume 39, Issue 5, September 2026.
Staurosporine drives non‐canonical melanocyte maturation through β‐catenin‐dependent actin remodeling. Functional maturation enhances dendrite architecture and melanogenic differentiation without inducing melanocyte proliferation, providing a biological framework for restoring functional melanocytes in acquired hypopigmentary disorders.

Natural Agents for Preventing Skin Damage Induced by Visible Light: A Systematic Review of Preclinical and Clinical Evidence

Photodermatology, Photoimmunology &Photomedicine, Volume 42, Issue 5, September 2026.
ABSTRACT Background/Purpose Visible light (VL), and particularly high‐energy visible light (HEVL), reaching Earth's surface has emerged as a relevant contributor to skin damage. VL has been implicated in oxidative stress, inflammation, pigmentation disorders, and photoaging, especially in individuals with darker skin phototypes.
