Common questions

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.
