This review discusses the effects of visible light on human skin, highlighting its role in pigmentation, thermal damage, and the treatment of several skin conditions, while noting limited sunscreen protection against it; no new clinical results are reported.

This review discusses the role of the circadian clock in skin functions such as cell proliferation and UV protection and reports no new results; the authors note its potential in studying immune regulation and seasonal behaviors.

This review study focused on various in vitro methods to evaluate skin permeation and retention of sunscreens, highlighting the importance of assessing sunscreen penetration due to widespread nanomaterial usage and advancements in cosmetic formulation.

This article reviews the basics of hair follicle biology, laser/tissue interactions, and hirsutism and hypertrichosis causes, discussing the long-pulsed alexandrite laser's role in hair reduction without reporting new clinical results.

This review discusses the impact of various exogenous agents on hair, such as cosmetics and radiation, but reports no new experimental results.

This study reports that retinol acetate inhibited the pro-oxidant effects of benoxaprofen on polymorphonuclear leucocytes in vitro.

Skin aging reflects overall body aging and can indicate internal health conditions.

The researchers found that SPF50+ sunscreens provided the highest DNA protection against solar-simulated radiation in a reconstituted human epidermis model, with formulation type not affecting efficacy for a given SPF.

This case report describes the diagnosis of pseudoporphyria in a hemodialysis patient, highlighting the importance of discontinuing causative medications and advising patients on sun protection to manage this photosensitive condition.

This review discusses various skin conditions affecting women throughout their lives and highlights the pharmacist's role in advising on management and treatment, but it reports no new clinical results.

This article discusses localized repigmentation of hair, suggesting it may be an indicator of underlying melanoma, and emphasizes the need for careful diagnostic evaluation.

This study found that a polyherbal sunscreen cream, F4, containing Camellia sinensis, Vitis vinifera, and Silybum marianum extracts demonstrated strong antioxidant and photoprotective properties, similar to synthetic sunscreens.

This review explores adult female acne, focusing on its multifactorial causes, treatment options, and impact on quality of life, but reports no new clinical results.

This study investigated single-cell changes in photoaged skin, revealing distinct cell clusters and increased activity in PD-L1 and PD-1 pathways in sun-exposed areas, enhancing understanding of UVA-induced skin damage and potential prevention targets for photoaging and UV-induced skin cancers.

This abstract suggests that sun damage may thin scalp tissue, potentially affecting hair transplant outcomes due to increased risk of necrosis or poor growth.

This study found that acetyl zingerone methyl ether (MAZ) in hair dyes and haircare products may reduce oxidative damage, improve hair condition, and enhance the longevity and quality of dyed hair color.

This study discusses the potential of microbial exopolysaccharides as safer cosmetic ingredients compared to synthetic chemicals like parabens and BHA, which may cause skin damage and cancer; exopolysaccharides offer benefits like antimicrobial and antioxidative effects without harmful impacts.

This study observed that exposing human hair keratins to heat or UV treatments led to modifications in cysteine residues, disrupting crucial disulphide bonds and potentially reducing the structural integrity of hair similar to prolonged styling or sunlight exposure.

This editorial synthesizes research on UV-induced skin damage, highlighting potential therapeutic strategies by mapping cellular changes, identifying molecular mechanisms, demonstrating melanocyte protection, and proving combination therapy effectiveness in conditions like vitiligo.
