Among harmful environmental factors that contribute to extrinsic aging, long-term effects of repeated exposure to ultraviolet light are the most significant and are referred to as photoaging. Photoaging is a multisystem degenerative process that involves the skin and skin support system. It is a cumulative process and depends primarily on the degree of

Alleviation of photoaging‐associated
Inorganic sunscreens containing the UV filters titanium dioxide (TiO2) and/or zinc oxide (ZnO) alleviated various biomarkers of photoaging in human dermal fibroblasts, at a gene and protein level. The study provides novel insights that observe the impact of inorganic photoprotection through the molecular biology of skin.

Multi-Omics Analysis Reveals Photodynamic Therapy Ameliorating Skin Photoaging by Improving Cellular Senescence Through Mitohormesis-Mediated Reduction of Citrate Content. [PDF]
Ultraviolet‐induced skin photoaging involves cellular senescence. Low‐dose photodynamic therapy (PDT) counteracts this by triggering mitochondrial ROS and mitohormesis, which improve metabolism and ameliorate senescence, leading to reduced wrinkles and enhanced skin barrier.

Assessment of Subepidermal Low-Echogenic Band via High-Frequency Ultrasound for Evaluating the Efficacy of Platelet-Rich Plasma Injection in Treating Facial Skin Photoaging: A Case Series. [PDF]
ABSTRACT Background Facial skin photoaging manifests as wrinkles, laxity, roughness, enlarged pores, telangiectasia, pigmentation, and dermal structural changes. Histologically, dermal collagen degradation and dermal‐epidermal junction disruption form the subepidermal low‐echogenic band (SLEB) on ultrasound.

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

Sunscreens - Which and what for? [PDF]
It is well established that sun exposure is the main cause for the development of skin cancer. Chronic continuous UV radiation is believed to induce malignant melanoma, whereas intermittent high-dose UV exposure contributes to the occurrence of actinic ...

Labisia pumila extract protects skin cells from photoaging caused by UVB irradiation [PDF]
Labisia pumila (Myrsinaceae), known as "Kacip Fatimah," has been used by many generations of Malay women to induce and facilitate child birth as well as a post partum medicine. However, its topical application on skin has not been reported yet.
