Ceramides
Definition
Lipid molecules that make up approximately 50% of the skin's outer barrier. They prevent transepidermal water loss (TEWL) and protect against environmental aggressors. Ceramide 1, 3, and 6-II are the most studied forms.
Why it matters for dupe shopping
Augustinus Bader's TFC8 complex is primarily a ceramide-delivery system. Budget alternatives that include the same ceramide types (check INCI for 'Ceramide NP', 'Ceramide AP', 'Ceramide EOP') can replicate the barrier function at a fraction of the cost.
