This study found that adapalene-loaded microemulsions significantly enhanced the drug's penetration through guinea pig skin compared to an aqueous suspension, with factors like surfactant ratios and the water-oil phase balance affecting the transfollicular drug delivery efficiency.

This study observed that both TCA (35%) and GA (70%) chemical peels improved skin morphology and stimulated bulge stem cells in albino rats, with no significant difference between the two agents.

This study found that a high dose of LustrivaTM, containing biotin and silicon, significantly increased hair thickness and reduced facial wrinkle depth in women with thinning hair compared to a placebo, without any reported adverse events.

This study concluded that shikonin, a small molecule derived from herbal extract, promotes wound healing and reduces inflammation in mice by activating the PI3K/Akt signaling pathway.

This study found that retinoic acid and a retinol complex formulation showed different permeation and compound localization in a skin equivalent model, with unique lipid changes observed with only the retinol formulation.

This study found that RXR and RAR proteins were detectable in normal human skin, suggesting they may play a role in epidermal cell differentiation and hair and gland physiology.

This review consolidates evidence on 93 plant species used in Zimbabwe for treating 21 skin-related conditions, reporting antimicrobial, anti-inflammatory, and antioxidant properties, though safety data remains inconsistent.

This review discusses the evolutionary history of keratins and reports no new results, highlighting key events that contributed to the development of mammalian hair and integument.

This review explores theories on the evolution of hair from synapsid scales and glands, proposing mechanisms supported by comparative studies, but reports no new experimental findings.

This research reports that the polyG fragment within the Hoxc13 protein alters its gene regulatory functions, which could have influenced mammalian hair evolution by affecting pathways related to hair follicle development.

This study analyzed the molecular evolution and functional divergence of the Dkk gene family, finding accelerated evolution in Aves and Reptilia and identifying functional differences that may impact hair follicle development via Wnt signaling inhibition.

This review found that while forensic DNA phenotyping and health applications for pigmentation genetics show potential, factors like phenotype definition and population diversity present challenges to accurate genotype-to-appearance predictions.

This study found that the unique crest feather formation in Polish chickens is driven by a 195-bp duplication in the HoxC10 gene region, which alters gene expression by modifying the genomic structure, suggesting a mechanism for diverse integumentary appendages in birds.

In this study, researchers used advanced four-dimensional optical imaging techniques to observe changes in skin afflicted with acne, finding increased epidermal thickness, keratinized hair follicles, inflammation, and aggregated blood flow, helping to distinguish between inflammation and reparative phases of acne progression.

This review discusses the various applications of platelet-rich plasma in dermatology, particularly its potential in esthetic dermatology and hair and scalp conditions, but reports no new clinical findings.

This review discusses advancements in skin microphysiological systems, such as 3D bioprinting, skin organoids, and skin-on-a-chip, and their effectiveness in emulating human skin functions for research and preclinical applications, highlighting the potential for replacing animal testing with these innovative technologies.

This study reports that six shampoo brands in Saudi Arabia generally comply with the national specifications, demonstrating good physicochemical properties such as foam stability and pH levels.

This study found that Quantitative Mass Spectrometry Imaging offers precise localization and quantification of active compounds in skin tissues, demonstrating benefits over traditional LC-MS in drug penetration studies.

This study found that topical valproate has minimal potential to cause skin irritation, suggesting it can be applied safely to human skin.

This review discusses the advantages and limitations of various hair loss evaluation methods but reports no new results; it emphasizes the importance of cautious interpretation for these diagnostic tools.

This study found that intralesional triamcinolone acetonide is effective for treating localized patchy alopecia areata, with dermoscopy aiding in early detection of clinical response and adverse effects.

This study found that intralesional steroid treatment led to significantly more hair regrowth in alopecia areata patients than narrow band ultraviolet B therapy, while their combination did not enhance effectiveness.

In this study, females with hirsutism showed higher levels of certain androgens and reported more frequent symptoms such as infertility and increased skin greasiness compared to those without hirsutism.

This review examines human-relevant in vitro models for studying pigmentation disorders, identifying both challenges and advancements in replicating human pigmentation processes and disease-specific pathology in vitro.

This study found that the MIRA technique, which customizes needle length and injection angle guided by ultrasound, improved structural and esthetic outcomes for cellulite treatment compared to standard methods.

This study aimed to identify the factors that influence the clinical severity of scalp seborrheic dermatitis, although specific results are not reported.

This study found that the ThriveCo Anti-Dandruff Pre-Shampoo Treatment, containing ZenscalpinTM, significantly reduced dandruff by 54.79% after 8 days and improved scalp health, with most participants reporting reduced flaking, dryness, and itchiness, and no noted adverse events.

This study evaluated the physicochemical characteristics, safety, and efficacy of six herbal and six synthetic shampoos and found that all products performed well in various tests, with no skin irritancy observed, suggesting that both types can be considered safe for use.

QMSI effectively maps and quantifies drug distribution in skin tissues.

In this study, the researchers developed a computer-aided imaging system to quantitatively measure baldness in Chinese women with female pattern hair loss, potentially improving the precision of severity evaluation compared to traditional scales.
