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

This article discusses hair loss linked to lithium treatment but reports no new clinical findings.

This study found that the activation of ER‑β increased keratinocyte proliferation and gene expression related to epidermal regeneration, enhancing wound healing in both cell models and rats.

This study found that platelet-rich plasma improved the healing of skin wounds in sheep compared to honey by reducing early inflammation and enhancing collagen synthesis and organization.

This study found that melatonin-loaded nanoparticles improved antidepressant effects and HPA axis regulation in pinealectomized rats, compared to free melatonin, through controlled-release properties.

This study reported that a novel filler, BM-PHA, demonstrated similar efficacy and safety to Restylane Perlane in treating moderate to severe nasolabial folds over 24 weeks, showing only minor local side effects and similar improvements in wrinkle severity scores between the two treatments.

In this study, researchers found that exosomes derived from Pinctada martensii mucus can effectively inhibit melanin production in melanoma cells and zebrafish without adverse effects, potentially offering a promising therapeutic strategy for treating pigmentary disorders by modulating the NF-κB signaling pathway.

This study investigated non-laser methods for removing permanent makeup using plant extracts, testing their decolorization effects on mice through tattooing and electroporation techniques.

This study found that extreme morning and evening chronotypes exhibited significant differences in the timing of circadian clock gene expression in hair follicle cells.

This study concluded that an endogenous circannual rhythm of prolactin secretion in mouflon influences their seasonal hair growth and moulting cycle, which varies under different photoperiodic and melatonin treatments.

In this study, silencing BMAL1 and PER1 genes increased melanogenic activity in follicular and epidermal melanocytes, suggesting that peripheral circadian clocks may regulate melanin pigmentation.

PMS nanoparticles improve damaged hair by protecting and restoring its surface and color.

This manuscript reports on the first case of perforating necrobiosis lipoidica in Colombia, marking the 19th documented case worldwide.

Isolated patchy heterochromia with pili annulati can occur without other health issues.

This study found that peanut agglutinin binding patterns after neuraminidase pretreatment can help differentiate malignant melanoma from nevocellular nevus in skin specimens.

This study observed that melatonin treatment reduced cellular damage and apoptosis in the intestinal epithelium of rats with acute necrotizing pancreatitis compared to untreated rats.

The new method can measure sleep-related hormones in hair effectively and could help track long-term sleep patterns.

This study found that silencing clock genes BMAL1 or PER1 in human hair follicles increased melanin content and melanocyte activity, suggesting these genes influence pigmentation.

This study introduced and evaluated a new dermoscopic feature, pigmented rings with central clearing, for improving the diagnosis of melasma and differentiating it from similar conditions.

This study suggests that pili annulati is likely more common than traditionally thought, highlighting the importance of recognizing its characteristic clinical and trichoscopic features for accurate diagnosis.

The authors concluded that utilizing clock gene expression from hair follicle cells may improve circadian-phase estimation in clinical settings, aiding the detection of circadian-related sleep problems despite social time constraints.

This study found that intense pulsed light treatment achieved a mean of 85% hair reduction in two patients with faun tail, although local anesthesia may be needed due to severe pain associated with neurological abnormalities.

In this study, a cosmetic product with nano encapsulated cysteamine plus sunscreen significantly improved melasma symptoms and quality of life in adult women over 84 days, compared to sunscreen alone, without any medically relevant intolerance.

This study identified melatonin as a potential treatment for rosacea and Alzheimer's disease, suggesting it may help by modulating inflammatory and vascular signaling pathways.

The researchers found that melatonin implantation in Cashmere goats influenced PDGFA gene expression and hair growth cycles, indicating it may control hair phase transformation from growth to catagen and telogen.

This study found that systemic administration of NDP-MSH, a melanocortin receptor agonist, provided neuroprotective effects on dopaminergic nigrostriatal neurons in a mouse model of Parkinson's disease, reducing neuroinflammation and suggesting a role for regulatory T cells in these neuroprotective effects.

This study investigated a nanostructured system using PS-b-PAA diblock copolymer for incorporating the hydrophobic photosensitizer ClAlPc, finding it effective in causing cellular damage in Caco-2 cells under light while demonstrating no cytotoxicity without light, suggesting its potential use in photodynamic therapy.

Polarizing light microscopy can easily and reliably diagnose congenital keratinizing disorders like Netherton syndrome.
