This case report describes a rare pedunculated follicular hamartoma on the nasal septum of a 77-year-old Japanese male, emphasizing its unique clinical and pathological features.

This review examined and discussed the role of dermis-derived factors in the regulation of melanogenesis, noting their significance in both normal and abnormal mammalian skin conditions, suggesting an underexplored area of study compared to dermal and epidermal influences.

In this study, researchers found that negative pressure fractional microneedle radiofrequency significantly improved periorbital wrinkles, hydration, and dermal thickness in patients with periorbital aging, while also increasing orderly collagen and elastic fibers, with minimal adverse effects reported.

This review examines the use of microneedles for treating alopecia areata, highlighting their ability to enhance drug delivery through the skin by bypassing the outer barrier and promoting hair growth with minimal invasiveness.

Understanding skin, hair, and nails is crucial due to their complexity and impact on health.

This study found that treatment with mercuric acetate modifies the elastic properties of Lincoln wool fibers more rapidly than human hair, explaining the enhanced unshrinkable quality of wool under certain conditions.

This study found no significant histologic differences in skin structure based on age, sex, or woodchuck hepatitis virus infection status among woodchucks.

This study reviewed literature on using vegetable oils to prevent skin aging, highlighting their antioxidant properties and their role in combating free radicals, which leads to extrinsic aging, while also noting Brazil's important contribution to this field with its rich natural resources.

Diagnosing and treating CCCA requires understanding multiple causes and using various diagnostic tools.

This review found limited but suggestive evidence that Calcium Hydroxylapatite may promote skin regeneration through increased collagen production, cell proliferation, and angiogenesis, although most studies had methodological limitations.

This study found that Pomiferin may effectively stimulate extracellular matrix protein expression in skin and scalp models, with results comparable to retinol, suggesting potential as a topical treatment ingredient.

In this study, intradermal injection of GCSF-mobilized peripheral blood stem cells from young pigs rejuvenated skin in aged pigs by increasing collagen, elastin, and cell renewal rates.

The researchers reported that marine-derived saccharides, specifically L-fucose and chondroitin sulphate disaccharide, supported skin and hair health by promoting cellular proliferation, enhancing extracellular matrix production, and aiding the hair cycle's growth phase, potentially minimizing aging effects.

This review examines the mechanisms behind pathological scarring like hypertrophic scars and keloids, highlights the limitations of current treatments, and suggests that biomaterial-enabled delivery of anti-fibrotic statins, such as atorvastatin, may offer a promising therapeutic avenue for managing these scars.

In this comprehensive review, researchers reported that macromolecules like type I collagen, keratin, and ceramides enhance hair health by improving follicular function and increasing hair density, strength, shine, and resilience, as shown in various in vitro, animal, and human studies.

HA-iMSC-EVs can improve skin aging by boosting cell growth and restoring collagen and elastin.

This study found that the wild-derived mouse strain Mus pahari has fragile skin that separates at subdermal levels under moderate force, potentially due to altered extracellular matrix development.

This article reviews how biopolymers are utilized in cosmetics, highlighting their biodegradable and non-toxic properties, recent structural developments, novel applications, and safety considerations in the formulation of skin, hair, and oral care products.

This study found that full thickness wounds in Lanyu pigs led to altered molecular expression and abnormal skin structure, without regenerating key epithelial cells thought to aid in skin regeneration.

This study found that applying a topical inhibitor of TGF-β1 may enhance scar maturation and improve the appearance of hypertrophic scars in a nude mouse model after two weeks.

This study found that combining Aliaxin® Global Performance with Viscoderm® Skinkò E improved hydration and appearance of nasolabial folds more effectively than using Aliaxin® Global Performance alone.

This study found no qualitative skin differences during development between mutant hairless USP mice and BALB/c mice, except for enlarged cysts in the hairless strain.

The researchers concluded that hairless dogs can serve as an effective model for studying hypertrophic scarring due to their development of scars with morphological similarities to human hypertrophic scars.

This systematic review found that sole nanofat grafting in plastic and reconstructive surgery shows potential benefits for scar improvement and anti-aging, with increases in skin thickness, collagen, and elastic fibers, but the evidence level remains low and further research is needed.

The study concluded that local administration of in-vitro-expanded bone marrow-derived mesenchymal stem cells accelerates and promotes healing in full-thickness excisional wounds in adult male albino rats.

This study found that low-molecular-weight hyaluronate significantly improved the mechanical strength and elastic modulus of overbleached hair by enhancing hydrogen bond networks within keratin.

This study investigated the genetic factors influencing cashmere quality differences between Jiangnan cashmere goats and Changthangi pashmina goats, identifying 4,942 differentially expressed genes and highlighting 24 key genes related to hair follicle development and cashmere fiber formation.

This review article discusses microneedling as a non-surgical treatment option in dermatology, highlighting its benefits for scar improvement through collagen induction and reporting its popularity among practitioners due to its cost-effectiveness and simplicity.

In this study, FN-based fiber scaffolds designed using Rotary Jet-Spinning were shown to enhance wound healing and reduce scar formation in a mouse model, suggesting potential for regenerating healthy skin structure.
