- What are the best ingredients for the skin barrier?
- Ceramides, cholesterol, and fatty acids are the lipids that make up the skin barrier. Niacinamide stimulates ceramide production. Humectants like glycerin and hyaluronic acid help maintain hydration.
- Do ceramides actually work in skincare?
- Clinical studies show that ceramide-containing formulations can restore barrier function in conditions like eczema and dry skin. Formulation matters — ceramides need to be delivered in the right vehicle to be effective.
- What damages the skin barrier?
- Over-cleansing, harsh surfactants (SLS), low pH products, physical exfoliants used too frequently, and environmental factors like cold weather and UV damage can all degrade the skin barrier.
