Glycerin-based moisturizing lotion

Neat Petrolatum versus Neat SEFA versus Glycerin-Based Moisturizing Lotion... 

FIGURE 28.11 Site of glycerin-based moisturizing lotion from the 52-year-old female of Figure 28.10. The structure of the intercellular space is unusual, (a) Many areas contain amorphous and fibrous material in the intercellular space, (b) Other areas contain vesicles, membrane-bounded compartments, and a mesh-like material. Bar = 200 nm. 

FIGURE 28.13 Tape strips from a 48-year-old female, (a) Site of application of a commercial moisturizing body wash containing petrolatum. The appearance is typical of a person over age 40 with good skin condition. The corneocytes are closely apposed and lamellae are frequent, but the lamellae appear somewhat disorganized and amorphous/fibrous material is present between lamellae. Landmann units are nevertheless easy to find, as shown in the left intercellular space, (b) Site of application of a mild synthetic bar followed by a glycerin-based moisturizing lotion. The intercellular spaces contain amorphous and fibrous material as well as prominent wavy lamellae without a Landmann pattern. Bar =100 nm.
