In this study, researchers developed a 3D chitosan/polyvinyl alcohol-tannic acid nanofiber sponge that demonstrated effective hemostatic, antibacterial, and antioxidant properties without antibiotics, accelerated wound healing in vivo, and showed high biocompatibility with L929 cells, highlighting its potential as a wound dressing for clinical use.

In this study, polymeric micelles containing retinoic acid were found to improve targeted delivery to hair follicle structures in human skin more efficiently than a marketed retinoic acid gel, suggesting potentially safer and more effective acne treatment.

This review found the strongest evidence supporting azelaic acid's use in treating rosacea, with somewhat less evidence for its effectiveness in melasma and acne vulgaris, and weaker support for its use in conditions like hidradenitis suppurativa and keratosis pilaris.

This study found that valproic acid promoted human hair growth by increasing β-catenin levels, suggesting it may be a potential therapeutic option for alopecia.

In this study, Juvéderm repeat treatments maintained wrinkle correction in nasolabial folds for up to 21 months and required significantly less filler than the initial treatment, indicating potential benefits for patients.

This study observed that retinoic acid biosynthesis and signaling in hair follicles have a spatial and temporal regulation linked to distinct stages of the hair cycle in mice.

This study found that dimethylarsinic acid significantly accelerates skin tumor development in hair follicle-targeted K6/ODC transgenic mice.

This study found that surface modified nanoparticles showed increased skin permeation and improvement in allergic contact dermatitis, independent of the follicular pathway.

The researchers reported that carnosic acid and carnosol, extracts from rosemary leaves, specifically inhibit S. aureus virulence expression, suggesting potential topical treatments for atopic dermatitis flares.

This study found that betulinic acid inhibits hepatitis C virus replication by suppressing the NF-κB- and ERK1/2-mediated COX-2 pathway, suggesting its potential as a therapeutic supplement.

In a testosterone-induced BPH rat model, this study found that ursolic acid treatment significantly reduced prostate weight and hormone levels, suggesting it may inhibit BPH development.

This study found that VYC-15L (Juvéderm Volbella XC) was safe and effective for enhancing lip and perioral areas, achieving higher lip fullness improvement and fewer severe injection site reactions compared to NASHA, with effects lasting up to one year.

In this study, 28.5% of patients with extensive alopecia areata had complete hair regrowth during treatment with squaric acid dibutylester, with outcomes linked to shorter alopecia duration and prompt dermatitis development.

This review highlights the role of all-trans retinoic acid in regulating stem and progenitor cell proliferation and differentiation, suggesting its potential to enhance treatments in regenerative medicine and cancer.

This study found that a dopamine-methacrylated hyaluronic acid hydrogel enhances the efficacy of adipose-derived stem cells in promoting skin regeneration, potentially involving the Notch signaling pathway.

This study found that the retinoic acid derivative Ro 10-9359 cleared psoriasis lesions in over half of the patients, but most experienced side effects, including skin issues and altered liver enzyme levels.

This study found that topical valproic acid significantly increased hair count in male patients with moderate androgenetic alopecia compared to placebo over 24 weeks.

This study found that IGF1, retinoic acid, and dexamethasone increase IGFBP-3 production in cultured human dermal papilla cells, potentially inhibiting IGF1 action on hair growth.

This study found that a combination of low-fluence Q-switched 1064 nm Nd:YAG laser, hydroquinone cream, and oral tranexamic acid showed promising results for Riehl’s melanosis in Asian patients, with no serious adverse events reported.

This study found that pediatric patients on valproic acid may experience hair loss due to reduced zinc and biotinidase levels within the first 3 months, with zinc depletion continuing to contribute by the 6th month.

In this study using a mouse model and human hair follicle cells, shikimic acid was found to promote hair growth and may serve as a new therapeutic agent for alopecia.

This research found that hyaluronic acid increased cell proliferation and type I collagen more effectively than poly-L-lactic acid in both human fibroblast cultures and rat dermis.

This review found that most studies support the effectiveness and safety of using hyaluronic acid fillers and laser treatments together for facial rejuvenation, but highlights that the evidence is limited to small, nonrandomized studies and additional research is necessary.

This article reviews the molecular interactions involved in hair follicle cycling and highlights the role of dermal papilla cells, but it presents no new research findings.

This review highlights GA-mediated nanoparticles for liver-targeting drug delivery in liver cancer treatment and reports no new clinical results.

This study found that proper levels of retinoic acid, controlled by the enzyme Cyp26b1, are essential for normal hair follicle development and morphogenesis in mice.

This study found that biodegradable PLA particles released fluorochromes in a time-dependent manner on human skin, with BP-PLA particles releasing rapidly and DiAsp-PLA particles providing sustained release and accumulation in hair follicles.

This study found that the reproductive function of female hairdressers may be negatively affected by long-term exposure to permanent-waving solutions containing thioglycolic acid, raising concerns about its potential carcinogenic effects.

This study explored a keratin, sodium alginate, and carboxymethyl chitosan hydrogel modified with tannic acid and found it to have promising wound-healing qualities, including similar elasticity to human skin, antimicrobial and antioxidant properties, and effective water retention. These attributes suggest potential applications in biomedical engineering.

This study observed that in mouse hair follicles, enzymes Aldh1a2 and Aldh1a3 have distinct expression patterns that suggest they are involved in different signaling pathways during the hair cycle.
