Your cells are surrounded by a very important type of lipid, called phospholipids. Phospholipids consist of a hydrophilic (or 'water loving') head and a hydrophobic (or 'water fearing') tail. Phospholipids like to line up and arrange themselves into two parallel layers, called a phospholipid bilayer. This layer makes up your cell membranes and is critical to a cell's ability to function.
On a film or modeling set, a makeup artist may spend six to eight hours doing makeup for the day. For an individual client appointment, the time span may be an hour to three hours. If a makeup artist is working for a bridal party, then he or she may spend the entire day working with clients.
