This study used in vivo confocal microscopy and a ResNet34 deep learning model to classify meibomian gland images with an AUROC greater than 0.95, indicating its potential for automatic diagnosis and screening of meibomian gland dysfunction.

The researchers reported that in hairless mice, epidermal cell division orientations and epidermal thickness varied by body site, with dorsal and ear epidermis primarily dividing parallel to the basement membrane, unlike hind paw and tail epidermis.

This study concluded that combining the Shumin treatment instrument with oral doxycycline provides better clinical outcomes for rosacea than combining red light therapy with doxycycline, while both regimens improved quality-of-life scores and reduced Demodex counts.

In this case report, narrowband-UVB phototherapy successfully treated a rare instance of Graham Little-Piccardi-Lassueur syndrome, a variant of lichen planopilaris, as investigated through non-invasive imaging techniques.

This study used advanced optical imaging techniques to investigate nanoparticle and dye penetration in human skin, finding that nanoparticles mainly resided in the stratum corneum and accumulated in skin folds and hair follicles, while highlighting that sunscreen-based nanoparticles appear unlikely to pose safety concerns.

This review outlines the practical use of reflectance confocal microscopy in dermatology, detailing its applications and considerations for diagnosing various skin conditions, but reports no new findings.

This study found that combining dermoscopy with reflectance confocal microscopy is more sensitive and specific than using either method alone for assessing vitiligo disease activity and treatment response. Additionally, specific characteristics observed via these techniques correlated with either good or poor treatment outcomes.

This study found that skin computed tomography may effectively identify epidermoid cysts by revealing features consistent with histopathology, potentially serving as a non-invasive diagnostic alternative to biopsies.

This study found that both reflectance confocal microscopy and optical coherence tomography can visualize detailed hair follicle abnormalities in various skin disorders, but larger, higher-quality studies are needed for clinical implementation.

This study demonstrates that the newly developed portable reflectance confocal microscope (PRCM) offers real-time, noninvasive monitoring of wound healing processes by visualizing skin morphology in both mice and humans.

In this study, R-CSLM showed promise in evaluating hair shaft diseases by providing high-quality images of hair structures, although further development is necessary for follicle and perifollicular area analysis.

This study demonstrates the use of microscopy-guided laser ablation to create a highly structured 3D hydrogel-based organotypic skin model with folliculoid structures, potentially useful for studying hair follicle development or bioactive substance screening.

This study explored using 3D models derived from reflectance confocal microscopy to better understand and differentiate melanoma on sun-damaged skin, suggesting enhanced diagnostic possibilities.

This study found that combining optical clearing methods with light-sheet fluorescence microscopy allows detailed 3D visualization of normal and pathological human skin biopsies, revealing differences in epidermal thickness and volume.

This review discusses the strong correlation between reflectance confocal microscopy images and horizontal histopathology in diagnosing skin tumors, highlighting the reliability of this non-invasive technique; no new clinical results are reported.

Dermoscopy is useful for many health professionals, not just dermatologists, in improving skin condition diagnoses and reducing unnecessary biopsies.

This review article examines the current understanding of frontal fibrosing alopecia, noting its prevalence in different demographics and the roles of genetic and environmental factors in its pathogenesis, while highlighting that treatment approaches remain varied and lack standardization.

This review discusses the role of scalp imaging techniques in trichology for researching drug delivery and toxicology, without presenting new clinical results.

This review discusses various non-invasive methods for diagnosing alopecia areata, highlighting that trichoscopy signs like short vellus hairs and yellow dots are sensitive indicators of the condition, while advanced imaging techniques provide valuable information on hair follicle status and scalp inflammation.

This review explores new theories, diagnostic tools, and management strategies for primary cicatricial alopecia but reports no new clinical findings.

This article reviews advances in the histologic evaluation of alopecia and hair-related disorders, without presenting new clinical results.

This article presents a comprehensive overview of hair microscopy techniques and their diagnostic potential for systemic and cutaneous disorders, emphasizing its usefulness in resource-limited settings and highlighting the underutilization of this non-invasive method due to lack of awareness.

This study found that transethosomal gel loaded with propranolol hydrochloride prolonged drug release and increased peak plasma concentration compared to an oral tablet, suggesting a promising alternative for delivery.

Dermoscopy greatly improves melanoma diagnosis and reduces unneeded surgeries.

This narrative review discusses the evolution and diverse medical applications of laser technologies, particularly in dermatology and skin biology, without reporting new research findings.

This review outlines various clinical methods for assessing ageing skin and discusses their application in supporting the efficacy claims of anti-ageing treatments, but it reports no new clinical results.

The study reported a significant genotype–phenotype correlation in prepubescent males with XLHED, particularly in the severity of skin and hair manifestations between those with different EDA mutations.

The human hair follicle can store topical compounds and be targeted for drug delivery with minimal side effects.

This study found that dermatoscopy can quickly and non-invasively detect facial vellus hair involvement in patients with alopecia frontal fibrosante, occurring frequently and associated with specific facial lesions.

This systematic review provides an in-depth evaluation of non-invasive imaging and biophysical methods for diagnosing and monitoring vitiligo, emphasizing the need for studies with larger sample sizes to verify their use in clinical practice and research.
