Study and Evaluation of Topically Applied Ceramides onto Disrupted Skin Barrier
Svobodová, Marie ; Kováčik, Andrej (advisor) ; Vraníková, Barbora (referee)
Department of Pharmaceutical Technology Author: M S b S , Ph.D. Title of diploma thesis: Study and Evaluation of Topically Applied Ceramides onto Disrupted Skin Barrier Skin is the largest organ of the human body and serves several key functions, such as protection against external influences and regulation of body temperature. Healthy skin is able to maintain the integrity and stability of the organism due to its complex structure. The skin is composed of several layers of cells, including the stratum corneum (SC), which forms the main protective barrier. Ceramides (CER) are one of the main types of barrier lipids found in the SC. These lipid molecules, along with other lipids, create a hydrophobic matrix that protects the skin from dehydration and other external influences. The lack of CER in the skin barrier leads to the disruption of its function and the worsening of the skin condition. This is associated with many diseases, such as dermatitis, psoriasis, and others. The study of CER in the SC is important to understand the mechanisms of skin protection and to develop new therapeutic approaches for the treatment of skin diseases. Topical administration of barrier lipids, especially CER, is one possible treatment route for skin diseases. Therefore, the aim of this work was to prepare...

Study of Topical Ceramide Application
Kulhánková, Roksolana ; Kováčik, Andrej (advisor) ; Vraníková, Barbora (referee)
Charles University, Faculty of Pharmacy in Hradec Králové Department of Pharmaceutical Technology Author: Roksolana Kulhánková Supervisor: doc. PharmDr. Andrej Kováčik, Ph.D. Title of diploma thesis: Study of topically administred ceramides The human stratum corneum (SC) is the uppermost layer of the epidermis, which is made up of several layers of corneocytes. The space between the corneocytes is filled with barrier lipids, i.e., ceramides, cholesterol, and fatty acids, which are represented in an equimolar ratio. The arrangement of intercellular lipids has a significant effect on the barrier properties of the skin. Damaged skin barrier (e.g., in atopic dermatitis) is associated with a lack of lipids in the SC lipid matrix, which is reflected in increased trans-epidermal water loss and deterioration of skin quality (e.g., severe dryness, flaking, and cracks). One of the potential ways to restore the skin barrier is the topical administration of barrier lipids, especially ceramides (Cer). The goal of this work was to study the effect of topically administered Cer (very long-chain Cer AP alone or in combination with ultra-long-chain Cer EOS) on model-damaged SC and their effect in the process of restoring barrier function. Several topically administered formulations (creams) were prepared, which...
