Abstract
Dermatological products constitute a big segment of the pharmaceutical market. From conventional products to more advanced ones, a wide variety of dosage forms have been developed till current date. A representative of the advanced delivery means is carrier-based systems, which can load large number of drugs for treatment of dermatological diseases, or simply for cosmeceutical purposes. To make them more favorable for topical delivery, further incorporation of these carriers in a topical vehicle, such as gels or creams is made. Therefore in this review article, an overview is compiled of the most commonly encountered novel carrier based topical delivery systems; namely lipid based (nanoemulsions, microemulsions, solid lipid nanoparticles [SLNs] and nanostructured lipid carriers [NLCs]), and vesicular carriers (non-deformable, such as liposomes, niosomes, emulsomes and cerosomes, and deformable, such as transfersomes, ethosomes, transethosomes, and penetration enhancer vesicles), with special emphasis on those loaded in a secondary gel vehicle. A special focus was made on the commonly encountered dermatological diseases, such as bacterial and fungal infections, psoriasis, dermatitis, eczema, vitiligo, oxidative damage, aging, alopecia, and skin cancer.

Abstract
Nowadays, the incidence of acute bacterial skin and skin structure infection (ABSSSI) is increasing. The increased bioavailability and reduced drug resistance of antibiotics are crucial to obtain a more effective treatment response in these infections. These favorable properties could be achieved by different drug delivery systems such as liposomes. In this study, nanosized, radiolabeled tedizolid phosphate liposomal formulations were prepared and evaluated with their in vitro cellular binding capacity and biocompatible profile for topical treatment of ABSSSI. Liposomes were characterized by evaluation of their visual inspection, particle size (about 190-270 nm), zeta potential value (around 0), and encapsulation efficiency (nearly 10%). The release rate of tedizolid phosphate from liposomes was also studied using dialysis membranes and evaluated kinetically. The stability of formulations was observed at three different temperatures and humidity conditions for 28 days. Afterward, liposomes were labeled with 99mTc, and the optimal amount of reducing agent (stannous chloride) was determined as 500 μg in this direct labeling procedure. All liposome formulations were successfully radiolabeled with high efficiency and exhibited high radiochemical purity (> 80%) during 6 h in different media. Furthermore, the cellular bindings of liposomal formulations were evaluated in human skin fibroblast cells by measuring the radioactivity. Higher radioactivity values were obtained in CCD-1070Sk cells incubated by liposome formulations compared to sodium pertechnetate. This finding suggested that liposomal formulation increased the cellular binding of radioactivity. By the result of our study, nanosized, tedizolid phosphate encapsulated liposome formulation was found to be a favorable carrier system in the treatment of ABSSSI.

Abstract
Acne is a common skin disease that affect over 80% of adolescents. It is characterized by inflammation of the hair bulb and the attached sebaceous gland. To date, many strategies have been used to treat acne as a function of the disease severity. However, common treatments for acne seem to show several side effects, from local irritation to more serious collateral effects. The use of topical vesicular carriers able to deliver active compounds is currently considered as an excellent approach in the treatment of different skin diseases. Many results in the literature have proven that drug delivery systems are useful in overcoming the toxicity induced by common drug therapies, while maintaining their therapeutic efficacy. Starting from these assumptions, the authors reviewed drug delivery systems already realized for the topical treatment of acne, with a focus on their limitations and advantages over conventional treatment strategies. Although their exact mechanism of permeation is not often completely clear, deformable vesicles seem to be the best solution for obtaining a specific delivery of drugs into the deeper skin layers, with consequent increased local action and minimized collateral effects.

Abstract
Clinical utility of conventional oral therapies is limited by their inability to deliver therapeutic molecules at the local or targeted site, causing a variety of side effects. Transdermal delivery has made a significant contribution in the management of skin diseases with enhanced therapeutic activities over the past two decades. In the modern era, various biomimetic and biocompatible polymer-lipid hybrid systems have been used to augment the transdermal delivery of therapeutics such as dermal patches, topical gels, iontophoresis, electroporation, sonophoresis, thermal ablation, microneedles, cavitational ultrasound, and nano or microlipid vesicular systems. Nevertheless, the stratum corneum still represents the main barrier to the delivery of vesicles into the skin. Lipid based formulations applied to the skin are at the center of attention and are anticipated to be increasingly functional as the skin offers many advantages for the direction of such systems. Accordingly, this review provides an overview of the development of conventional to advanced biomimetic lipid vesicles for skin delivery of a variety of therapeutics, with special emphasis on recent developments in this field including the development of transferosomes, niosomes, aquasomes, cubosomes, and other new generation lipoidal carriers.

Abstract
INTRODUCTION Differentiation therapy using all-trans retinoic acid (ATRA) revolutionised the treatment of acute promyelocytic leukaemia to such an extent that it is now one of the most curable types of leukaemia, with ATRA and anthracycline-based chemotherapy providing cure rates above 80%. Isotretinoin is used to treat chronic acne. Here, we examine the information described in recent patents and the extent to which new findings are influencing extending retinoid-based differentiation therapy to other cancers, as well as the development of new therapies for other disorders. AREAS COVERED A search has been performed on the literature and worldwide patents filed during 2014 to the present time, focusing on synthetic agonists and antagonists of retinoic acid receptors and novel compositions for the delivery of these agents. EXPERT OPINION New potential therapeutic applications have been described, including lung, breast and head and neck cancers, T cell lymphoma and neurodegenerative, metabolic, ophthalmic, muscle, and inflammatory disorders. Recent patents have described the means to maximise retinoid activity. Two decades of efforts to extend retinoid-based therapies have been disappointing and new synthetic retinoids, target diseases and modes of delivery may well resolve this long standing issue.

Abstract
BACKGROUND Conventional topical tretinoin formulation is often associated with local adverse events. Nanogel formulation of tretinoin has good physical stability and enables good penetration of tretinoin into the pilo-sebaceous glands. AIM The present study was conducted to assess the efficacy and safety of a nanogel formulation of tretinoin as compared to its conventional gel formulation in the treatment of acne vulgaris of the face. MATERIALS AND METHODS This randomized, active controlled, multicentric, phase IV clinical trial evaluated the treatment of patients with acne vulgaris of the face by the two gel formulations locally applied once daily at night for 12 wk. Acne lesion counts (inflammatory, non-inflammatory & total) and severity grading were carried out on the monthly scheduled visits along with the tolerability assessments. RESULTS A total of 207 patients were randomized in the study. Reductions in the total (72.9% vs. 65.0%; p = 0.03) and inflammatory (78.1% vs. 66.9%; p = 0.02) acne lesions were reported to be significantly greater with the nanogel formulation as compared to the conventional gel formulation. Local adverse events were significantly less (p = 0.04) in the nanogel group (13.3%) as compared to the conventional gel group (24.7%). Dryness was the most common adverse event reported in both the treatment groups while peeling of skin, burning sensation and photosensitivity were reported in patients using the conventional gel only. CONCLUSION In the treatment of acne vulgaris of the face, tretinoin nanogel formulation appears to be more effective and better tolerated than the conventional gel formulation.

Abstract
The objective of this work was to evaluate liposome-containing gel formulations for the sustained, site-specific delivery of celecoxib (CXB). Liposomes composed of phosphadtidylcholine (and various amounts of cholesterol (Ch) were prepared using thin film hydration and characterized for encapsulation efficiency, vesicle size, and drug-excipient interaction using differential scanning calorimetry and Fourier-transform infrared spectroscopy. The selected liposome formulation was incorporated in different gel formulations: the Ch ratio affected the encapsulation efficiency of the drug, by increasing Ch ratio up until 1:1 the encapsulation efficiency increased. Further increasing the Ch ratio resulted in decreasing encapsulation efficiency. In vitro drug release and skin permeation studies showed sustained release and enhanced permeation compared with gel formulations containing free drug. In the rat paw edema test, the anti-inflammatory activity of the selected liposomal gel formulation was higher and more sustained compared with that of the nonliposomal gel formulation containing free drug. These results suggest that the liposome-containing gels are promising formulations for sustained, site-specific delivery of CXB.

Abstract
Conventional carriers for skin delivery encounter obstacles of drug leakage, scanty permeation and low entrapment efficiency. Phospholipid nanogels have recently been recognized as prominent delivery systems to circumvent such obstacles and impart easier application. The current review provides an overview on different types of lecithin nanostructured gels, with particular emphasis on liposomal versus microemulsion gelled systems. Liposomal gels investigated encompassed classic liposomal hydrogel, modified liposomal gels (e.g. Transferosomal, Ethosomal, Pro-liposomal and Phytosomal gels), Microgel in liposomes (M-i-L) and Vesicular phospholipid gel (VPG). Microemulsion gelled systems encompassed Lecithin microemulsion-based organogels (LMBGs), Pluronic lecithin organogels (PLOs) and Lecithin-stabilized microemulsion-based hydrogels. All systems were reviewed regarding matrix composition, state of art, characterization and updated applications. Different classes of lecithin nanogels exhibited crucial impact on transdermal delivery regarding drug permeation, drug loading and stability aspects. Future perspectives of this theme issue are discussed based on current laboratory studies.

Abstract
INTRODUCTION Topical photodynamic therapy (PDT) refers to topical application of a photosensitizer onto the site of skin disease which is followed by illumination and results in death of selected cells. The main problem in topical PDT is insufficient penetration of the photosensitizer into the skin, which limits its use to superficial skin lesions. In order to overcome this problem, recent studies tested liposomes as delivery systems for photosensitizers. AREAS COVERED This paper reviews the use of different types of liposomes for encapsulating photosensitizers for topical PDT. Liposomes should enhance the photosensitizers' penetration into the skin, while decreasing its absorption into systemic circulation. Only few photosensitizers have currently been encapsulated in liposomes for topical PDT: 5-aminolevulinic acid (5-ALA), temoporfin (mTHPC) and methylene blue. EXPERT OPINION Investigated liposomes enhanced the skin penetration of 5-ALA and mTHPC, reduced their systemic absorption and reduced their cytotoxicity compared with free drugs. Their high tissue penetration should enable the treatment of deep and hyperkeratotic skin lesions, which is the main goal of using liposomes. However, liposomes still do not attract enough attention as drug carriers in topical PDT. In vivo studies of their therapeutic effectiveness are needed in order to obtain enough evidence for their potential clinical use as carriers for photosensitizers in topical PDT.

Abstract
Recent advances in the field of nanotechnology have allowed the manufacturing of elaborated nanometer-sized particles for various biomedical applications. A broad spectrum of particles, extending from various lipid nanostructures such as liposomes and solid lipid nanoparticles, to metal, nanocrystalline and polymer particles have already been tested as drug delivery systems in different animal models with remarkable results, promising an extensive commercialization in the coming years. Controlled drug release to skin and skin appendages, targeting of hair follicle-specific cell populations, transcutaneous vaccination and transdermal gene therapy are only a few of these new applications. Carrier systems of the new generation take advantage of improved skin penetration properties, depot effect with sustained drug release and of surface functionalization (e.g., the binding to specific ligands) allowing specific cellular and subcellular targeting. Drug delivery to skin by means of microparticles and nanocarriers could revolutionize the treatment of several skin disorders. However, the toxicological and environmental safety of micro- and nanoparticles has to be evaluated using specific toxicological studies prior to a wider implementation of the new technology. This review aims to give an overview of the most investigated applications of transcutaneously applied particle-based formulations in the fields of cosmetics and dermatology.

BACKGROUND Increasing antibiotic resistance of Propionibacterium acnes and growing awareness on the side effects of topical and systemic drugs in the treatment of acne vulgaris by physicians and patients have paved the way for a search into new efficacious and safe treatment modalities such as photodynamic therapy (PDT). Although the efficacy of PDT using 20% 5-aminolevulinic acid (ALA) cream has been established, phototoxic side effects limit its use. The 5-ALA concentration can be lowered by a factor of 40 by changing the vehicle of 5-ALA from a moisturizing cream to liposome encapsulation. OBJECTIVES Assessment of the efficacy and the safety of PDT using 5-ALA 0.5% in liposomal spray and intense pulsed light (IPL) in combination with topical peeling agents (Li-PDT-PC) in acne vulgaris. MATERIALS AND METHODS 32 patients suffering from acne participated in this randomized, prospective, single blind study. All patients were treated with Li-PDT-PC. During the study nine patients were additionally treated with topical or systemic antibiotics (Li-PDT-PC-AT). These patients were removed from the study although their results were recorded. Results After a mean period of 7.8 months and a mean number of 5.7 treatments the mean total number of lesions dropped from 34.6 lesions to 11.0 lesions, resulting in a mean improvement of 68.2%. Side effects were minimal. Additionally, an intention to treat analysis was conducted. CONCLUSION Photodynamic therapy of acne vulgaris using 5-ALA 0.5% liposomal spray and IPL in combination with topical peeling agents is safe and efficacious, even in patients with acne recalcitrant to standard therapy.

Abstract
Topical retinoids represent a mainstay of acne treatment because they expel mature comedones, reduce microcomedone formation, and exert anti-inflammatory effects. The first-generation retinoid tretinoin (all-trans retinoic acid) and the synthetic third-generation polyaromatics adapalene and tazarotene are approved for acne treatment by the US FDA, whereas topical tretinoin, isotretinoin (13-cis retinoic acid), and adapalene are accredited in Canada and Europe. Topical retinoids have a favorable safety profile distinct from the toxicity of their systemic counterparts. Local adverse effects, including erythema, dryness, itching, and stinging, occur frequently during the early treatment phase. Their impact varies with the vehicle formation, skin type, frequency and mode of application, use of moisturizers, and environmental factors such as sun exposure or temperature. The broad anti-acne activity and safety profile of topical retinoids justifies their use as first-line treatment in most types of non-inflammatory and inflammatory acne. They are also suitable as long-term medications, with no risk of inducing bacterial resistance, for maintenance of remission after cessation of initial combination therapy.

Abstract
Vesicular phospholipid gels (VPGs) represent semi-solid phospholipid dispersions. Their morphology is truly vesicular with aqueous compartments both within the core of the vesicles and in-between the vesicles. VPGs are suited to carry both hydrophilic, amphiphilic and lipophilic drugs. Their drug load is stable since there is no concentration gradient between the vesicles' core and the surrounding water phase. VPGs are suited to release drugs in a controlled manner, and thus may serve as depot implants. When blended with excess aqueous medium VPGs are easily converted into small-sized liposome (SUV) dispersions showing high encapsulation efficiencies for all kinds of drugs. VPG-formulations with various cytostatic drugs have been tested successfully in human xenografts. Obviously, the vesicles protect the drugs from premature metabolic inactivation and/or elimination and guide them to solid tumors with enhanced vascular permeability (passive targeting). Furthermore, when mounted on a filter support, VPGs represent a tight diffusion barrier suitable for screening of oral drug permeability, as demonstrated by a set of 21 drug compounds. Permeability values were shown to fit well with human absorption in vivo, indicating that the model is suited for rapid screening of passive transport properties of new chemical entities.

Abstract
This review focuses on the therapeutic utility of liposomes in the treatment of inflammatory disorders, and aims to offer the reader an overview of the in vivo results obtained with liposomally encapsulated anti-inflammatory and immune suppressive drugs. The past 30 years has clearly indicated the added value of liposomes in the search for solutions for the delivery problems encountered. However, only a few liposomal anti-inflammatory therapeutics have entered the clinic. Reasons for the hurdles existing in the translation of promising preclinical findings to clinical studies are discussed.

Abstract
Acne is the most common cutaneous disorder of multifactorial origin with a prevalence of 70-85% in adolescents. The majority of the acne sufferers exhibit mild to moderate acne initially, which progresses to the severe form in certain cases. Topical therapy is employed as first-line treatment in mild acne, whereas for moderate and severe acne, systemic therapy is required in addition to topical therapy. Currently, several topical agents are available that affect at least one of the main pathogenetic factors responsible for the development of acne. Although topical therapy has an important position in acne treatment, side effects associated with various topical antiacne agents and the undesirable physicochemical characteristics of certain important agents like tretinoin and benzoyl peroxide affect their utility and patient compliance. Novel drug delivery strategies can play a pivotal role in improving the topical delivery of antiacne agents by enhancing their dermal localization with a concomitant reduction in their side effects. The current review emphasizes the potential of various novel drug delivery strategies like liposomes, niosomes, aspasomes, microsponges, microemulsions, hydrogels and solid lipid nanoparticles in optimizing and enhancing the topical delivery of antiacne agents.

Abstract
Salicylic acid has been used widely in the treatment of dry skin conditions and also helps reduce acne symptoms. However, it suffers from the disadvantages of being a mild to strong irritant. Hence, its control can be achieved through encapsulation in liposomes. Liposomes were prepared by the conventional thin film hydration technique as described by Bangham et al. (J. Mol. Biol., 1965). The prepared liposomal dispersions were then characterized for entrapment efficiency, particle size by transmission electron microscopy (TEM), phase transition studies by differential scanning calorimetry (DSC), and lamellarity by nuclear magnetic resonance (NMR). The results showed the formation of bilayered liposomes in the particle size range of 0.2-0.8276 microm with a maximum entrapment efficiency of 42.6%. The liposomes stored at 4-5 degrees C demonstrated maximum stability as compared to those stored at any other temperature.

Abstract
Acne vulgaris is a very common skin disease. Most patients present with mild to moderate acne comedonica or papulopustulosa grade I-II. The first-line treatment for these cases is generally via the topical route, whereas systemic medication is indicated when higher severity grades with small nodes or scarring occur. There are several topical agents available that affect at least one of the main pathogenetic factors responsible for the development of acne: hyperseborrhoea, hyperkeratosis, microbial colonisation and inflammatory and immunological reactions. Topical retinoids have a comedolytic and anticomedogenic activity, and some of them have anti-inflammatory potency. Azelaic acid and benzoyl peroxide have a moderate to strong antibacterial effect without inducing bacterial resistance, which is becoming a significant problem with the increasing use of topical antibacterials. Topical antiandrogens may soon be available for the treatment of the pathogenetic factor hyperseborrhoea. The transdermal penetration and the resulting systemic bioavailability of the various topical agents has not been widely considered. Apart from the retinoids, which can be associated with the risk of embryotoxicity/teratogenicity, and clindamycin, which might cause pseudomembranous colitis, information on the systemic pharmacokinetics of other topical agents is not readily available. There is still no consensus on the safe use of topical retinoids in pregnancy, and the occurrence of pseudomembranous colitis after the topical use of clindamycin does not appear to be of clinical relevance. In general, topical anti-acne agents are well tolerated and, as would be expected from their limited transdermal uptake, other significant safety concerns have not so far arisen.

Abstract
Intensive efforts have been made to establish a novel, scalable liposomal preparation technique suitable for the entrapment of even large proteins into liposomes. We have developed a new technique based on the principles of the ethanol injection technique. Herein, the principal item is the crossflow injection module, specifically designed for this purpose. This unit has the benefit of defined and characterized injection streams and permits liposome manufacture regardless of production scale, as scale is determined only by the free disposable vessel volumes. Previous publications demonstrated that the crossflow injection technique that we have developed meets all of the above-mentioned requirements. The present paper describes the entire three-step production process, consisting of encapsulation, separation of non-entrapped protein by continuous crossflow filtration, and retrieval of rh-Cu/Zn-SOD by additional filtration. Results of consecutive lots were compared, based on well-defined quality criteria.

Abstract
A novel topical benzovl peroxide (BP) gelformulation containing liposomal BP was shown to significantly reduce local irritation relative to its nonliposomal BP gel (plain BP gel) preparation and also to improve clinical efficacy (almost twofold) in the treatment of acne. BP liposomes were prepared, optimized, and formulated into a carbopol 934gel base. Drug release evaluated using dialysis membrane has repeatedly shown that a new topical gel formulation containing liposomal BP (liposomal BP gel) significantly reduced BP penetration. Clinical evaluation data were also compared with those obtained with liposomal tretinoin (TRE) gel in an earlier investigation of ours. The overall improvement in terms of percentage reduction in total number of skin lesions demonstrated almost similar results for both BP and TRE. However, variation was observed in the treatment of separate types of lesions in which liposomal TRE gel was found to be more effective in treating comedones and liposomal BP gel in treating papules and pustules. Also, the liposomal gel formulation of both the drugs significantly reduced the local adverse effects, thereby improving patient compliance.

Abstract
The findings of this investigation thus conclusively demonstrate the promising role of concomitant therapy of liposomal TRE and BP gels in treating acne patients. Allthough their use improved the therapeutic response, more benefits of the liposomal form of drugs were observed in terms of reduction in adverse effects of therapy, thus fostering better patient compliance. It can be concluded that this study underscores the potential utility of concomitant therapy with liposomal TRE and BP gels in the treatment of acne. However, the role of liposmal formulations may only be established after clinical evaluation of alarge number of patients, with a special focus on the adverse symptoms of therapy.
