Thixotropic gels are the preferred choice in the collection of platelet-rich plasma as an easy solution to operator variability. One often unnoticed shortcoming is the entrapment of platelets in the gel layer's uppermost surface. We provide instructions to optimize platelet yield, ie, agitation to re-suspend platelets, setting the optimal G-force and time of centrifugation, and the essential use of a horizontal swing bucket centrifuge. We conclude that this technique represents a new clinical and research direction, particularly to optimize platelet counts. We therefore encourage others to utilize this technique in future endeavors. J Drugs Dermatol. 2024;23(11):979-985. doi:10.36849/JDD.7983.

Background: Botulinum toxin (BT) has become one of the most frequently sought aesthetic procedures for wrinkle reduction.

Objective: This study investigated the effectiveness and safety of a novel device using radiofrequency (RF) and high-intensity facial muscle stimulation (HIFES) in patients injected with BT.

Methods: Twelve patients were divided into an Active (N=10) and a Control group (N=2), where the Active received four treatments and the Control none. The facial expressions documented by digital photographs (neutral) and videos (frown, smile, surprise expressions) were taken at all visits (baseline, after last Tx, 1 and 3-month follow-ups) and were evaluated using the Global Aesthetic Improvement Scale (GAIS) and 3D automated analysis. The subject's therapy comfort and satisfaction were assessed.

Results: The Active group reported high satisfaction with treatment comfort (6.3±0.2 points on the 7-point Likert scale). 3D analysis showed reduced wrinkle severity (37.4%) and volume increase (+1.5 mL) on the cheeks at 3 months. GAIS evaluation demonstrated the most prominent improvement in smiling facial expression by 2.2±0.1 points. No adverse events were observed.

Conclusion: The study results suggest that the combination of HIFES and synchronized RF is a safe and effective treatment for improving facial appearance and muscle tone in patients injected with BT. J Drugs Dermatol. 2024;23(11):937-942.  doi:10.36849/JDD.7938.

Retinoids are derivatives of vitamin A prominently used in cosmeceuticals to reverse signs of photoaging. Retinaldehyde (retinal) is 10x more bioavailable than retinol and is gaining traction in the skincare industry for being the strongest over-the-counter retinoid. This study evaluated the efficacy and tolerability of a novel retinal formulation including peptides, ceramides, and lipids, designed to sustain the potency of the retinal and enhance delivery to reverse clinical signs of photoaging. This study was a trial of the test product (Retinal Night Advanced 0.1% Retinal Firming Treatment, Dr. Whitney Bowe Beauty, Greenwich, CT) in which 32 female subjects were enrolled. 47% of subjects had skin of color (Fitzpatrick Skin Type III-VI) and 57% had sensitive skin. Subjects applied the test product 3 nights weekly to the face, neck, and chest for 8 weeks. Fine lines of the face had 12% visible change by week 8 (P<0.0001). Fine lines on the chest showed progressive visible improvement of 11% at week 2 (P=0.0005) and 19% at week 8 (P<0.0001). There was a 19% improvement in visible hyperpigmentation of the face by the 8-week mark (P<0.0001). Visible texture of the face improved by 5% (P=0.0078) and pores improved by 20% at week 8 (P<0.0001). Patch testing revealed no signs of sensitization or irritation. This clinical study demonstrates that this retinal formulation is safe, well-tolerated, and effective in improving the appearance of fine lines, hyperpigmentation, texture, and pores.

Over the past several years, the field of acne treatments, which had been relatively unchanged, has welcomed a variety of innovations. From new molecules and mechanisms of action to previously implausible fixed combination products, prescribers have more topical treatment options than ever before.

Background: Rhinophyma, a benign condition resulting in nasal sebaceous tissue hypertrophy, predominantly affects Caucasian males. There are numerous surgical and medical treatments for rhinophyma with varying degrees of success. This review aims to provide a comprehensive overview of ablative therapies, highlighting our preferred treatment approach.

Methods: This review analyzes the evidence behind ablative lasers in treating rhinophyma, with a focus on the 10600 nm carbon dioxide (CO2) and 2940 nm erbium: yttrium-aluminum-garnet (Er:YAG).

Results: Both CO2 and Er:YAG have demonstrated efficacy in treating rhinophyma. CO2 laser ablation results in a higher incidence of scarring and hypopigmentation. Er:YAG has high water absorption, which results in less thermal damage, allowing for quicker healing and fewer complications.

Conclusion: Management of rhinophyma can remain challenging; however, ablative lasers are an effective treatment. Both laser types have promising outcomes, each with different advantages and complications. In particular, Er:YAG presents fewer complications compared to CO2 lasers.

Keloids are thickened raised scars that develop due to injury and grow beyond the boundaries of their original wound, mostly affecting individuals with skin of color. This review explores the use of energy-based devices to treat keloids, both using laser monotherapy and in combination with other drugs. Laser therapy alone has shown efficacy in treating keloids. Combination laser therapy has better keloid reduction when administered with steroids, 5-fluorouracil (5-FU), and verapamil. However, monotherapy has had less adverse reactions including dermal atrophy and local pain. Therefore, physician discretion is essential when considering treatment. This review highlights the efficacy of energy-based devices (EBDs), alone and in combination. It also reveals the need to have tailored approaches with patients. Further research is needed to develop more comprehensive treatment standards for keloids using EBDs alone or in combination. J Drugs Dermatol. 2024;23(11):998-1002. doi:10.36849/JDD.8210R1.

Background: Facial hyperpigmentation, characterized by the excessive production of melanin in the skin, is a prevalent dermatological concern affecting individuals of various ethnic backgrounds.

Aims: To evaluate the safety and efficacy of a multi-wavelength 589/1319 nm dual-pulse duration laser device for the treatment of hyperpigmentation Patients/Methods: A total of 17 healthy women (mean [SD] age of 43.4 [11.6] with skin phototype II-IV) were enrolled in this prospective, single-center study. Eligible participants received up to 3 treatments spaced 3 to 5 weeks apart with 2 follow-up visits at 4 and 12 weeks after the final treatment. Assessments included investigator ratings of skin quality, global aesthetic improvement, and hyperpigmentation. Safety and tolerability were monitored throughout the study.

Results: Significant improvements in hyperpigmentation and skin quality were observed at the 2 follow-up visits from baseline in most patients per investigator assessments. Patient satisfaction was high, and treatments were safe with transient self-resolving side effects such as erythema.

Conclusions: Laser treatments using a dual-wavelength 589/1319nm device significantly improve facial hyperpigmentation in patients of various skin types. J Drugs Dermatol. 2024;23(11):943-947. doi:10.36849/JDD.8196.

The greatest risk factor for skin cancer is exposure to ultraviolet (UV) rays of the sun. Among the three types of solar radiation (UVA, UVB, UVC), UVB rays are most commonly associated with skin cancer. UVB exposure promotes the formation of cyclobutane pyrimidine dimers (CPDs) in the DNA of cells in the epidermal skin layers, which can lead to mutations as DNA repair machinery attempts to repair the damage. These mutations can lead directly to skin carcinogenesis. Previous studies in animal and in human ex vivo skin models have shown that topical application of acyclothymidine dinucleosides protects DNA from UV-induced damage by preventing the formation of CPDs and helps initiate repair through the activation of DNA repair enzymes. Here we review the biological evidence leading to the development and formulation of ProteXidineTM (Topix Pharmaceuticals, Inc., Amityville, NY), as a UV protective agent for topical human application. We also provide clinical data pertaining to four ProteXidineTM formulations (test materials 1-4) tested for their abilities to reduce CPDs in an ex vivo human skin tissue model.

Biologic medications have revolutionized the treatment of many dermatologic conditions. However, their use during pregnancy and breastfeeding is a subject of ongoing concern due to limited data on their safety in these populations. As the course of many inflammatory skin conditions is unpredictable during pregnancy and may worsen, biologics are important therapeutic tools for disease stabilization in this patient population. In this review, we provide a comprehensive summary of the gestational safety profile of biologics commonly used in dermatology and provide recommendations during pre-conception, pregnancy, and post-partum periods. We also examine fertility data, placental transfer of biologics, and postpartum immunosuppression/immunomodulation data. J Drugs Dermatol. 2024;23(11):1010-1015. doi:10.36849/JDD.7816R1.
