α-Arbutin ameliorates UVA-induced photoaging through regulation of the SIRT3/PGC-1α pathway

open access: yesFrontiers in Pharmacology
Owing to its tyrosinase inhibitory activity, α-arbutin has been added to several skin care products as a skin-lightening agent. However, the protective effect of α-arbutin against ultraviolet A (UVA)-induced photoaging has not been well investigated. The

Action of tyrosinase on alpha and beta-arbutin: A kinetic study. [PDF]

open access: yesPLoS ONE, 2017
The known derivatives from hydroquinone, α and β-arbutin, are used as depigmenting agents. In this work, we demonstrate that the oxy form of tyrosinase (oxytyrosinase) hydroxylates α and β-arbutin in ortho position of the phenolic hydroxyl group, giving ...

Combining the Salt‐Tolerant Plants Limonium algarvense Erben and Polygonum maritimum L. Promotes Synergistic Bioactivities for Enhanced Cosmetic Applications

open access: yesChemistry &Biodiversity, Volume 23, Issue 1, January 2026.
ABSTRACT The demand for natural and sustainable ingredients in dermo‐cosmetic formulations has promoted the use of coastal salt‐tolerant plants as novel bioresources. This study evaluated aqueous extracts of Limonium algarvense and Polygonum maritimum, two salt‐tolerant coastal plants and their mixtures (3:1, 1:1, 1:3, w/w) for antioxidant, metal ...

Navigating Solute Carrier Transporters—A Comprehensive Review of Functionalized Small Molecule Probes for Target Identification and Characterization

open access: yesMedicinal Research Reviews, Volume 46, Issue 1, Page 238-271, January 2026.
ABSTRACT Solute carrier transporters (SLCs) are integral membrane proteins that play pivotal roles in maintaining cellular homeostasis by mediating the transport of a diverse range of substrates across cell membranes. With their involvement in fundamental physiological processes such as nutrient uptake, neurotransmitter signaling, and drug transport ...

Targeting Melasma: Innovations in Pigment Deposition and Photoaging in Cosmetic Dermatology

open access: yesJournal of Cosmetic Dermatology, Volume 25, Issue 1, January 2026.
ABSTRACT Background Melasma is a chronic, relapsing hyperpigmentation disorder driven by complex interactions among genetic predisposition, hormonal fluctuations, UV exposure, oxidative stress, inflammation, and photoaging. Its psychosocial impact is substantial, especially among women with darker skin types, and treatment remains challenging due to ...
