Facial skin thickness varies significantly depending on the location on the face. It's not a uniform thickness across the entire face.
Regional Variations in Facial Skin Thickness
The thickness of facial skin ranges from approximately 1.51 mm to 1.97 mm. Research indicates that the thinnest skin is found around the radix (bridge of the nose) and dorsum (top of the nose), averaging 1.51 ± 0.55 mm. The thickest skin is typically located in the infraorbital region (area below the eye sockets), measuring approximately 1.97 ± 0.84 mm. Other areas, such as the forehead, cheeks, and temples, fall within this range, exhibiting varying degrees of thickness. One study found the average forehead skin thickness to be 1.70 mm.

- Thinnest: Radix and dorsum of the nose (around 1.51 mm)
- Thickest: Infraorbital region (around 1.97 mm)
- Average Forehead: 1.70 mm
It's important to note that these measurements represent averages, and individual variations exist due to factors such as age, genetics, and sun exposure. Furthermore, the term "skin thickness" often refers to the epidermis and dermis combined, not just the epidermis alone. The dermis, the thicker layer below the epidermis, contributes significantly to overall skin thickness.
Factors Affecting Facial Skin Thickness
Several factors influence the thickness of facial skin:
- Age: Skin naturally thins with age.
- Genetics: Individual genetic predisposition plays a role.
- Sun Exposure: Prolonged sun exposure can affect skin thickness.
- Underlying Conditions: Certain medical conditions can impact skin thickness.
Measuring Facial Skin Thickness
Various methods exist for measuring facial skin thickness, including ultrasound techniques. These techniques are often utilized in dermatological procedures and research to assess skin thickness accurately. [Source: Ultrasonographic analysis of facial skin thickness in relation to age...]

- The facial skin tended to become thicker in the order of the radix and dorsum, and the temple, supraorbital, forehead, perioral, cheek, and infraorbital areas (Table 3). Among the seven regions, the skin was thinnest at the radix and dorsum (1.51 ± 0.55 mm), and thickest in the infraorbital region (1.97 ± 0.84 mm; Fig.10-Jan-2019
