This article reviews treatments focused on stimulating collagen synthesis and improving skin appearance through methods like mechanical dermabrasion and laser surgery, but it reports no new clinical results.

This study found that long pulsed Nd: YAG laser is a safe and effective method for hair reduction in individuals with skin types IV and V, with significant improvements observed over six sessions.

This study found that the long-pulsed alexandrite laser effectively reduced hair growth with varying efficacy depending on the pulse duration, anatomic location, and number of treatments, without causing permanent adverse effects in skin types I–III.

In this study, the researchers reported the detailed anatomical structure of horse skin, including the composition and organization of the epidermis, dermis, and associated glands and follicles.

This study observed that hairless HRS/J mice were resistant to Bacillus anthracis infection at the skin's surface, suggesting resistance may be due to increased dermal neutrophils rather than non-functional hair follicles.

In this study, reflectance confocal microscopy was used to diagnose periorificial dermatitis, revealing specific skin changes such as hair follicle dilatation, increased vascular density, and inflammation, which help distinguish it from similar conditions.

This study found that chronic UVR exposure in mice and humans leads to a permanent loss of papillary fibroblasts in the upper dermis, which is associated with changes in the extracellular matrix.

This article reviews the role of androgen in male pattern hair loss and its impact on hair follicle miniaturization, but it does not present new research findings.

This study found that activation of the transcription factor Nrf2 in keratinocytes promotes wound healing in mice by expanding hair follicle stem cells, independent of changes in keratinocyte proliferation or migration.

This case report describes a 45-year-old woman with diffuse nonscarring alopecia characterized by hair thinning, increased catagen/telogen follicles, and mild inflammatory infiltrate, highlighting the diagnostic findings via scalp dermoscopy and biopsy.

This study suggests that using sebaceous glands from rat tail skin samples may effectively capture hair follicle stem cells, potentially aiding skin regenerative medicine when available tissue is limited.

This study provided a dynamic 4D atlas showing the development process of mouse hair follicles through a telescope-like model, revealing new insights into the origin of hair follicle stem cells.

In this study, the use of Endolift laser treatment significantly improved upper eyelid laxity and eyebrow height in nine patients, with evaluations conducted by blinded physicians showing notable cosmetic outcomes 6 months post-treatment.

In this study, researchers used atomic force microscopy to evaluate mechanical stiffness across different skin layers in six participants, finding the highest stiffness in the epidermis and lower stiffness as layers progress to subcutaneous tissue, enhancing understanding of skin's physical properties and aiding future research.

In this study, researchers developed a biopolymer-based dual-layer wound dressing that significantly improved healing outcomes in a 14-day rat model, reporting 94% wound closure by day 15 and enhanced tissue regeneration, swelling properties, and cell viability.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

This study found that MPEG-dihexPLA micelles significantly improved the skin deposition of tacrolimus compared to a marketed ointment, suggesting better targeted delivery with reduced systemic absorption.

This study found that actomyosin contractility in suprabasal keratinocytes influences the proliferation and differentiation of epidermal stem/progenitor cells by acting as a niche element in the skin.

This study found that adapalene-loaded nanospheres in a hyaluronic acid gel enhanced skin penetration and were nonirritant, making them potentially suitable for treating acne on oily skin.

This study developed a multifunctional bilayer dressing containing nanosilver and basic fibroblast growth factor, which improved wound healing by preventing bacterial penetration, promoting angiogenesis and hemostasis, and accelerating cell proliferation and migration, outperforming a control group by increasing healing rates by 47% in vivo.

In this study, elevated mRNA levels for serine-rich ultra high sulfur proteins were observed during active hair growth phases in mice, particularly in the forming hair structures and upper skin layers.

This study reports that eccrine sweat glands in mice predominantly develop on the footpads, offering a reference for skin research involving genetically engineered mice.

This article discusses keratosis pilaris, a common skin condition often considered a normal variant, and reviews its associations, progression, and available treatments without reporting new clinical results.

Laser technologies improve medical treatments and outcomes.

The study observed increased melanin and signs of skin aging in melasma-afflicted skin, with strong CK10 expression in the upper basal epidermis, potentially linked to excessive epidermal cell differentiation and aging.

In this study, researchers demonstrated that follicular tight junctions in porcine skin form a barrier to nanoparticle penetration, particularly in upper regions, which supports its use as a model for human skin.

This study examined camel skin histomorphology, finding that hair follicles were distributed singly in the upper lip but clustered in other body areas, and that sweat glands were associated only with large primary hairs.

Two cases of a rare skin condition were successfully treated with laser therapy, offering a non-surgical treatment option.

This study reported that a Megsin-Cre transgene enables genetic manipulation primarily in skin, forestomach, and esophagus tissues, offering a new tool for studying development and diseases in these areas.

This case report documents a successful response to griseofulvin and prednisolone treatment in a 12-year-old boy with lichen planopilaris, characterized by patchy hair loss and distinct skin changes.
