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

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 ...

Williamsia faeni sp. nov., an actinomycete isolated from a hay meadow [PDF]
The taxonomic status of an actinomycete isolated from soil collected from a hay meadow was determined using a polyphasic approach. The strain, designated N1350T, had morphological and chemotaxonomic properties consistent with its classification in the ...

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 ...

The Effect of α-Arbutin on UVB-Induced Damage and Its Underlying Mechanism
Ultraviolet radiation can heighten tyrosinase activity, stimulate melanocyte production, impede the metabolism of numerous melanocytes, and result in the accumulation of plaques on the skin surface.

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