Investigation of ex vivo Skin Penetration of Coenzyme Q10 from Microemulsions and Hydrophilic Cream

Autor: Konstanze Bosse, Efrem N. Tessema, Reinhard H.H. Neubert, Yahya Mrestani, Johannes Wohlrab

Publikováno v: Skin Pharmacol Physiol

Introduction: Coenzyme Q10 (CoQ10) has been widely used in topical and cosmeceutical products due to its cutaneous antioxidant and energizer effects. CoQ10 is found in a higher concentration in the epidermis compared to dermis. The epidermal level of

Delivery of oat-derived phytoceramides into the stratum corneum of the skin using nanocarriers: Formulation, characterization and in vitro and ex-vivo penetration studies

Autor: Tsige Gebre-Mariam, Efrem N. Tessema, Getahun Paulos, Reinhard H.H. Neubert, Johannes Wohlrab

Publikováno v: European Journal of Pharmaceutics and Biopharmaceutics. 127:260-269

Deficiency or altered composition of stratum corneum (SC) lipids such as ceramides (CERs), causing skin barrier dysfunction and skin dryness, have been associated with skin diseases such as atopic dermatitis and psoriasis, and ageing. Replenishing th

Potential application of oat-derived ceramides in improving skin barrier function: Part 1. Isolation and structural characterization

Autor: Tsige Gebre-Mariam, Bodo Dobner, Reinhard H.H. Neubert, Stefan Lange, Efrem N. Tessema

Publikováno v: Journal of Chromatography B. :87-95

The impaired epidermal barrier and skin dryness in chronic skin conditions such as atopic dermatitis, psoriasis and aged skin are associated with the depletion of ceramides (CERs) in the stratum corneum. Previously, the beneficial effects of phyto-CE

Structural characterization of plant glucosylceramides and the corresponding ceramides by UHPLC-LTQ-Orbitrap mass spectrometry

Autor: Admassu Assen Adem, Tsige Gebre-Mariam, Efrem N. Tessema, Alena Soboleva, Anteneh Belete, Andrej Frolov, Reinhard H.H. Neubert

Publikováno v: Journal of Pharmaceutical and Biomedical Analysis. 192:113677

Ceramides (CERs) play a major role in skin barrier function and direct replacement of depleted skin CERs, due to skin disorder or aging, has beneficial effects in improving skin barrier function and skin hydration. Though, plants are reliable source
