Atopic dermatitis is a chronic inflammatory disease of the skin, which is characterized by itching, erythema, and eczematous lacerations. It affects about 10 % of adults and approximately 15-20 % of children worldwide. As a result of genetic, immunologic, and environmental factors, the disease manifests itself with the impaired stratum corneum barrier and then immunological responses. Topical administration of corticosteroids and calcineurin inhibitors are currently used as the first strategy in the management of the disease. However, they have low skin bioavailability and some side effects. The nanocarriers as novel drug delivery systems could overcome limitations of conventional dosage forms, owing to increment of poorly soluble drug' solubility, then its thermodynamic activity and, consequently, its skin permeation. Also, side effects of the drug substances on the skin could be reduced by the nano-sized drug delivery systems due to encapsulation of the drug in the nanocarriers and targeted drug delivery of drug substances to the inflammated skin areas. Thereby, there have been available numerous research studies and patents regarding the use of nanocarriers in the management of atopic dermatitis. This review focuses on the mechanism of disease and development of nanocarrier based on novel drug release systems in the management of atopic dermatitis.

Background: Atopic dermatitis (AD) is a chronic inflammatory skin disorder characterized by itching and redness, affecting individuals of all ages and significantly impairing their quality of life. The prevalence of AD is rising, posing serious health concern. Relief of itching is a primary treatment objective; however, steroid treatments can lead to adverse effects, including skin barrier thinning.

Nemolizumab is an effective treatment for pruritus in atopic dermatitis, but it has a relatively high incidence of cutaneous adverse events (cAEs). To optimize the use of nemolizumab, we investigated the relationship between baseline severity in specific body areas and the frequency of cAEs. Our findings revealed that cases who discontinued treatment with nemolizumab had more severe erythema and edema/papulation on the trunk than those who continued nemolizumab.

Objectives: Atopic skin plays a significant etiological role in the development of prurigo nodularis (PN). In addition to atopic dermatitis (AD), atopic skin diathesis without eczema can also contribute to the development of PN due to its association with itching. This study aims to evaluate PN in terms of AD/atopic skin diathesis, associated comorbidities, and clinical findings.

Objective: To present and analyze eight clinical cases illustrating the use of rose stem cell-derived exosomes (RSCEs) in treating various dermatological conditions and to review current literature on plant-derived exosomes in medicine and dermatology.
Background: RSCEs possess low cytotoxicity, high biocompatibility, and effective cellular uptake, making them promising agents for dermatological therapies. A literature review included in the introduction and discussion covers the broader role of plant-derived exosomes, highlighting their therapeutic potential in skin treatment.
