FAQ
Q1: What do ceramides do?
A: Ceramides are the main lipid "mortar" between skin's cells, holding the barrier together so moisture stays in and irritants stay out.
Q2: What happens when ceramides drop?
A: The barrier leaks moisture (dryness, tightness) and admits irritants (redness, reactivity).
Q3: Do ceramide creams work?
A: Yes — formulas with ceramides plus cholesterol and fatty acids mirror skin's natural lipid structure and help rebuild it.
