Ceramides or shea butter: which one for your skin?

Ceramides are part of the skin's structure, while shea butter covers it. Both are fatty substances, but one fills an internal deficit and the other forms an external barrier.

Two fatty substances, two different approaches

Plug or supplement

Shea butter forms a lid: it prevents water from leaving without adding anything to the structure through which it escapes. A night cream with plant ceramides tackles the problem from the other end, and that's why butter provides quick relief but doesn't change anything in the long run.
