  • The need for further experiments in models that better recapitulate periocular skin complexity. The need for additional studies using hydration measurement methods using validated equipment and in vivo human models.

    PVA and HPMC E4M-based patches for periorbital hyperpigmentation containing açaí oil, barbatimão extract and hyaluronic acid: Preliminary evaluation of skin hydration · 2026 · DOI

  • There is a limited literature describing melasma in men. Extra-facial melasma is less frequently reported and is most often described in postmenopausal women.

    Extra-facial Melasma Presenting With Isolated Forearm Involvement in a Male Patient · 2026 · DOI

  • The presentation in this case - a male patient with isolated, symmetric involvement of the bilateral forearms - represents an uncommon clinical scenario and contributes to the limited literature describing melasma in men. Although there is limited literature directly addressing melasma development in previously burned skin, thermal injury is known to result in long-term alterations in melanocyte density, function, and dermal remodeling [8].

    Extra-facial Melasma Presenting With Isolated Forearm Involvement in a Male Patient · 2026 · DOI

  • This is a single case report with a short observation period. No statistical analysis was performed due to the small sample size. Longer-term evaluation is needed to establish the efficacy of the treatment.

    Autologous Fat Grafting for Mixed-Type Atrophic Acne Scars: A Case Report in Female · 2026 · DOI

  • There is a lack of evidence for the use of fat grafting in mixed-type atrophic acne scars. The current treatment options for atrophic acne scars are limited.

    Autologous Fat Grafting for Mixed-Type Atrophic Acne Scars: A Case Report in Female · 2026 · DOI

  • The field of non-light-based energy devices in dermatology is rapidly evolving, with emerging innovations and current evidence summarized in this review. There is a need for further research on the efficacy and safety of these devices.

  • 9.1. Integration with nanotechnology One of among the most promising methods to improve the effectiveness of anti-melasma formulations is the combination of nanotechnology and herbal treatment. Conventional herbal creams and gels frequently have drawbacks such limited stability, poor solubility, insufficient skin penetration, and quick active chemical breakdown. These difficulties can be solved by phytosomes, nanotechnology-based such carriers liposomes, niosomes, nanoemulsions, lipid solid nanoparticles (SLN), and nanostructured lipid carriers (NLC). These systems preserve and enhance the dermal absorption of bioactive herbal substances such as quercetin, glabridin from licorice, catechins from green tea, and curcumin from turmeric. For instance, research has demonstrated that SLN gels enriched with curcumin lessen pigmentation more successfully than traditional creams. In a comparable way, licorice extract liposomes reduce increasing bioavailability and skin penetration into the epidermis. These nano-formulations' controlled release characteristics enable long-lasting therapeutic activity, frequency, and improve patient compliance, making them an effective treatment for long-term ailments like melisma. improve epidermal retention and irritation while lower dosage and and lack extract quality, thorough carefully planned 9.2. Evidence-based herbal therapy scientific Evidence-based methods validation are essential for the future of herbal therapy in the treatment of melasma. Although preclinical research has shown promise for several herbal drugs, clinical data is frequently restricted because of small sample numbers, of inconsistent standardization. To assess effectiveness, safety, and results, long-term randomized controlled trials (RCTs) using standardized herbal extracts and contemporary administration methods are required. For research to be repeatable and consistent, turmeric or like curcumin active in standardized.
