Ceramides are a type of lipid that is found naturally in the skin. They work by forming a protective layer on the skin's surface. This layer helps to prevent water loss from the skin and to keep out irritants and allergens.

Yes, Ceramides are safe for most skin types, including sensitive skin.

Ceramides are generally well-tolerated by most people, but there is a small risk of irritation, especially with initial use. It is always a good idea to do a patch test on a small area of your skin before using any new product, including Ceramides.

Ceramides can be derived naturally or chemically. Natural Ceramides come from the extraction from plants and animals while chemically derived Ceramides are synthesized in a lab.
