Silica-based microencapsulation used in topical dermatologic applications.

Microencapsulation has received extensive attention because of its various applications. Since its inception in the 1940s, this technology has been used across several areas, including the chemical, food, and pharmaceutical industries. Over-the-counter skin products often contain ingredients that readily and unevenly degrade upon contact with the skin.

Efficacy and Safety of Microencapsulated Benzoyl Peroxide Cream, 5%, in Rosacea: Results From Two Phase III, Randomized, Vehicle-Controlled Trials.

Objective: A new formulation of benzoyl peroxide (E-BPO cream, 5%) entraps benzoyl peroxide (BPO) in silica microcapsules. This study assesses the efficacy, safety, and tolerability of E-BPO cream, 5%, in rosacea in two Phase III clinical trials.

Methods: In two 12-week, randomized, double-blind, vehicle cream-controlled Phase III trials, 733 subjects at least 18 years old with moderate to severe rosacea were randomized (2:1) to once-daily E-BPO cream, 5%, or vehicle.

Prevalence and Demographics of Truncal Involvement Among Acne Patients: Survey Data and a Review of the Literature.

Background: Truncal acne is frequently underdiagnosed despite affecting around half of those with facial acne. The objective was to provide an overview of the literature on the incidence of truncal acne according to age, gender, and acne severity.

Methods: A narrative review of data from recent large surveys and a literature search in PubMed on the incidence of truncal acne across subgroups of age, gender, and acne severity.

Nonantibiotic Properties of Tetracyclines in Rosacea and Their Clinical Implications.

Rosacea is one of the most common inflammatory skin diseases in the United States, with a complex pathophysiology. One of the major components of the pathophysiology of rosacea is an abnormal immune detection and response to stimuli. Tetracyclines and their derivatives, including minocycline and doxycycline, have anti-inflammatory properties independent of their antibacterial activity that correlate with certain aspects of the pathophysiology, and these drugs are often used by dermatologists to treat rosacea.

Open-label Extension Study Evaluating Long-term Safety and Efficacy of FMX103 1.5% Minocycline Topical Foam for the Treatment of Moderate-to-Severe Papulopustular Rosacea.

Efficacy and safety of FMX103 1.5% for papulopustular rosacea were previously demonstrated in two 12-week, Phase 3 studies. We sought to evaluate the safety and efficacy of FMX103 1.

Tolerability of tretinoin lotion 0.05% for moderate to severe acne vulgaris: a post hoc analysis in a black population.

Acne vulgaris (acne) is the most common dermatologic disorder seen in black patients. However, data are lacking on the effects of treatments, such as topical retinoids. Acne in black patients is frequently associated with postinflammatory hyperpigmentation (PIH), which can be of greater concern than the patient's acne and often is the main reason these patients seek a dermatologist consultation.

Minocycline 1.5% foam for the topical treatment of moderate to severe papulopustular rosacea: Results of 2 phase 3, randomized, clinical trials.

Background: Efficacious topical medications for rosacea are needed. FMX103 1.5% is a novel topical minocycline foam that may have therapeutic benefits in treating rosacea while minimizing systemic adverse effects due to its topical route of delivery.

Halobetasol 0.01% Lotion in the Treatment of Moderate-to-Severe Plaque Psoriasis of the Lower Extremities.

Background: Psoriasis is a chronic, immune-mediated disease that varies widely in its clinical expression. Topical corticosteroids (TCS) are the mainstay of treatment. Long-term safety remains a concern, limiting use, and posttreatment flare is common.

Safety and Efficacy of a Halobetasol 0.01%/Tazarotene 0.045% Fixed Combination Lotion in the Treatment of Moderate-to-severe Plaque Psoriasis: A Comparison with Halobetasol Propionate 0.05% Cream.

Topical corticosteroids (TCS) represent a mainstay of psoriasis treatment, though more potent formulations are not recommended for use for more than 2 to 4 weeks. We sought to investigate the safety and efficacy of once-daily halobetasol propionate 0.01%/tazarotene 0.

The Role of Cutaneous Microbiota Harmony in Maintaining a Functional Skin Barrier.

The skin is constantly exposed to various endogenous and exogenous factors that may impact its barrier function at the physical, mechanical, immunological, and microbial levels. These factors have the potential to initiate or exacerbate a variety of inflammatory skin conditions, especially those associated with barrier dysfunction. The barrier function of the skin depends upon a symbiotic relationship between resident microbial communities and host tissue.

Optimal management of papulopustular rosacea: rationale for combination therapy.

The pathophysiology of papulopustular rosacea (PPR) is primarily characterized by inflammation associated with several factors such as abnormal innate immune response, neurovascular dysregulation, stratum corneum barrier dysfunction, and depletion of antioxidant reserve, with no definitive evidence supporting an underlying microbial etiology. Several molecular inflammatory pathways have now been identified that enable the development of therapeutic agents that target the signs and symptoms of disease by modifying specific pathophysiological mechanisms. Available evidence demonstrates that topical and oral agents commonly used to treat PPR appear to modify some of these pathophysiological mechanisms and may prove to be complimentary when used in combination potentially leading to better therapeutic outcomes.
