Myth vs fact

Myth: A ceramide cream will clear any rash or long-term skin disease.
Fact: No. Ceramides can make dry, tight skin more comfortable, but eczema, psoriasis or a rash that won't settle needs a doctor.

What it is

Think of the top layer of skin as a brick wall: cells are the bricks, and ceramides, cholesterol and fatty acids are the mortar. Labels may list Ceramide NP, AP, EOP or Phytosphingosine.

What it does

It helps fill gaps in the barrier, cutting water loss and dryness. Several studies found less dryness after a few weeks with ceramide moisturisers. Formulas that pair ceramides with cholesterol and fatty acids are thought to work better.
