Ceramides:
Ceramides are a type of lipid (fat) that form the component of the outermost layer of the skin (epidermis, or more precisely, the stratum corneum). Ceramides are crucial for maintaining the skin barrier, as they hold the cells of the epidermis together, thus protecting the skin from drying out and from external germs and bacteria.
Vitamin A:
Vitamin A is a fat-soluble vitamin which controls several important functions in the body. While it's well-known for its importance in maintaining good vision, vitamin A also has numerous other benefits: it contributes to the normal function of skin and mucous membranes in the mouth, nose, intestines and reproductive organs, supports the immune system and works synergistically with iron in the synthesis of red blood cells.
According to the European Food Safety Authority (EFSA):
Vitamin A contributes to:
- to the maintenance of normal vision
- to a normal iron metabolism
- normal function of the immune system
- to the maintenance of normal skin
- to maintain normal mucous membranes
- Vitamin A has a function in cell specialisation
