Nicotinamide Improves Skin Photoaging in Mice by Delaying Cellular Senescence and Suppressing the Senescence-Associated Secretory Phenotype [PDF]

Current Issues in Molecular Biology
Nicotinamide (NAM), a precursor of nicotinamide adenine dinucleotide (NAD+), and NAD+ are integral to a variety of cellular processes. NAM supplementation has been shown to have benefits for cellular senescence.

Aging in elderly: Chronological versus photoaging

Indian Journal of Dermatology, 2012
Background: Skin is a window to aging changes, a biological reality. There is a dearth of studies regarding the various chronological (intrinsic) aging and photoaging (extrinsic) changes seen in Asians.

Interaction of TAGLN and USP1 promotes ZEB1 ubiquitination degradation in UV-induced skin photoaging

Cell & Bioscience, 2023
Background Ultraviolet A (UVA) irradiation can lead to skin damage and premature skin aging known as photoaging. This work found that UVA irradiation caused an imbalance between dermal matrix synthesis and degradation through the aberrant upregulation of

Far-infrared suppresses skin photoaging in ultraviolet B-exposed fibroblasts and hairless mice. [PDF]

PLoS ONE, 2017
Ultraviolet (UV) induces skin photoaging, which is characterized by thickening, wrinkling, pigmentation, and dryness. Collagen, which is one of the main building blocks of human skin, is regulated by collagen synthesis and collagen breakdown.

Hesperidin from Chenpi Ameliorates Skin Photoaging by Targeting HSPA1L to Stabilize GPX4 and Suppress Ferroptosis [PDF]

Antioxidants
Photoaging is an extrinsic skin aging process caused by chronic ultraviolet (UV) radiation. A core pathological feature of photoaging is excessive oxidative stress, which can further induce ferroptosis.

Comparison of histological measures of skin photoaging

Dermatology, 2011
Background: Dermal elastosis is considered the histological 'gold standard' for evaluation of skin photoaging, but the relation of the level of dermal elastosis to other histological indicators of photoaging is not clear.

Unveiling the dual-edged roles of melanocytes: Key insights into skin photoaging and therapeutic avenues

Pharmacological Research
The skin, the body's largest organ, serves as the primary barrier against external damage. Skin aging can act as a visible proxy and a triggering factor for systemic aging.
