An Injectable Biopolymer Hydrogel Complex (PN/HA/B3) for Facial Skin Redensification and General Rejuvenation: Clinical Report on Device Safety and Efficacy.

J Funct Biomater · May 2026

This study evaluated the safety and effectiveness of HYDRAGEL A2, an injectable medical device containing hyaluronic acid (HA), polynucleotides (PN), and niacinamide, for improving facial skin quality. These ingredients are increasingly recognized for their synergistic effects in aesthetic medicine, with HA and PN providing hydration and skin support, and niacinamide offering anti-inflammatory and antioxidant properties. A prospective, open-label clinical investigation was conducted on 42 female subjects (mean age 45 ± 1 years, Fitzpatrick skin phototypes II-V) to assess skin elasticity, hydration, and mild skin depression correction following cheek area injections.

L-Carnitine in Dermatology: A Systematic Review of Therapeutic Potential and Biomarker Applications.

J Cutan Med Surg · Mar 2026

L-Carnitine, an amino acid derivative critical for fatty acid metabolism, exhibits anti-inflammatory, antioxidant, and cytoprotective properties, with emerging applications in dermatology. This review explores its therapeutic potential, both topically and systemically, and its role as a biomarker in various skin disorders. A systematic search of Medline, EMBASE, and PubMed (1946-January 2025) was conducted, focusing on L-carnitine and dermatologic conditions, excluding acetyltransferases, acyltransferases, breast, and genetic metabolic diseases.

Applications of bakuchiol in dermatology: Systematic review of the literature.

J Cosmet Dermatol · Dec 2022

Bakuchiol (BAK), a meroterpene phenol abundant in the plant Psoralea corylifolia, is an emerging cosmeceutical agent with promising anti-aging, anti-inflammatory, and antibacterial properties. The trend for "clean" skincare products and search for anti-aging retinoid alternatives have poised BAK as a "must-have" ingredient in skincare. Our aim was to review the data for the applications of BAK in dermatology.

Iontophoresis-Based Topical Drug Delivery for Dermatologic Conditions: A Systematic Review.

Pharmaceuticals (Basel) · May 2026

The efficacy of topical therapies in dermatology is often limited by the barrier function of the stratum corneum, which restricts drug penetration. Iontophoresis is a non-invasive transdermal delivery technique that uses a low-intensity electrical current to enhance the transport of charged and polar molecules across the skin. It has emerged as a strategy to improve local drug bioavailability while minimizing systemic exposure.

Multitargeted Modulation of Skin Dullness by HNHT Formulation: Synergistic Inhibition of Melanogenesis, Glycation, and Lipofuscin Deposition.

J Cosmet Dermatol · May 2026

Skin dullness, characterized by pigmentation disorders and yellowing, is a major cosmetic concern in Asian populations. Lipofuscin exhibits ultraviolet (UV)/visible light spectral absorption, reduces skin reflectance, and contributes to dullness, whereas existing therapies targeting melanogenesis and glycation lack comprehensive efficacy. This study aimed to evaluate the multimodal anti-dullness effects of a novel formulation (HNHT: hyaluronic acid, niacinamide, hydrolyzed red algae, and tranexamic acid).

Drug-Induced Melasma in Patients on 5-Alpha Reductase Inhibitors: A Case Report.

Case Rep Dermatol · Dec 2026

Melasma is a chronic hyperpigmentation disorder with pathogenesis linked to hormonal mediation, ultraviolet and heat exposure, and genetic predisposition. Five-alpha reductase inhibitors (5-ARIs), including finasteride and dutasteride, are widely prescribed for treatment of benign prostatic hyperplasia (BPH) and off-label for androgen-mediated dermatologic conditions, yet pigmentary adverse effects are rarely reported. To date, only one case documenting melasma following 5-ARI use has been published.

Dietary patterns, metabolic pathways and metainflammation in hidradenitis suppurativa: a systematic review.

Front Immunol · Jan 2026

Dietary factors have been suggested to influence inflammatory skin diseases; however, their role in the pathogenesis and clinical course of hidradenitis suppurativa (HS) remains insufficiently understood. Increasing evidence suggests that HS is a systemic immunometabolic disease characterized by chronic low-grade inflammation and metabolic comorbidities such as obesity, insulin resistance, and metabolic syndrome. Dietary patterns may therefore influence HS activity through metabolic and inflammatory pathways.

Acne is the most prevalent skin disease globally, with a significant burden and limited therapeutic innovation. Although it has a multifactorial etiology, Cutibacterium acnes (C acnes) overgrowth is a key factor in driving inflammation in acne. Bacteriophages are a novel mechanism that can specifically target C acnes and are found in greater abundance on healthy skin compared to acne-prone skin.

The brain-gut-skin axis in inflammatory and disfiguring skin diseases: mechanistic insights, clinical correlations, and therapeutic strategies.

Emerging evidence suggests that the brain-gut-skin axis (BGSA) plays a critical role in the pathogenesis of inflammatory and disfiguring skin diseases. Conditions such as acne, atopic dermatitis, psoriasis, rosacea, vitiligo, and alopecia areata, once regarded as localized disorders driven mainly by cutaneous immune dysfunction, are now recognized as systemic conditions associated with neuroendocrine stress responses, gut microbial dysbiosis, and chronic low-grade inflammation.
