Tetraacetylphytosphingosine (TAPS) is an acetylated phytosphingosine derivative used in skincare to support the skin barrier, reduce transepidermal water loss, and provide soothing and anti-inflammatory effects. It functions as a precursor that can be converted to phytosphingosine and ceramide-related lipids within the skin.
