WebAcne skin demonstrates increased transepidermal water loss (TEWL) compared with healthy skin, which may be due, in part, to altered ceramide (CER) levels. We analysed ceramides in the stratum corneum of healthy and acne skin, and studied seasonal variation over the course of a year. Using ultraperformance liquid chromatography with electrospray ...

WebCeramides containing 6-hydroxysphingosine, a previously unknown long-chain base, have recently been found in human skin. The present study investigated whether human skin … WebThe synthesis of a ceramide with a 6-hydroxysphingosine base, a unique component of the human epidermal barrier, is reported. The key step involves a mild and selective trans-reduction of a triple bond using [Cp*Ru(CH 3 CN) 3]PF 6-catalyzed hydrosilylation followed by protodesilylation.The oxidation of sphingosine-based ceramide to 6-hydroxyceramide … calories in 4 oz of almond milk
