How thick are human epidermis and dermis respectively? Is the face the same as the body?

The thickness of human epidermis varies greatly, ranging from 0.07 to 1.2 mm, the palm and sole can reach 0.8 to 1.4 mm, while the cubital fossa is only 0.3 mm. The thickness of eyelid epidermis is 0. 1 ~ 0.5 mm, the thickness of general dermis is 0.4 ~ 2.4mm, and the thickness of back dermis is 0.3 mm.

The skin thickness on face and body is different. The thickness of skin varies from place to place. The back, nape, palm and sole are the thickest, and the armpit and face are the thinnest, with an average thickness of 0.5-4.0 mm. ..

Extended data:

Skin covers the whole body surface and is one of the largest organs in human body, accounting for about 16% of body weight. The adult skin area is about 1.2-2.0 square meters. The thickness of skin varies from place to place. The back, nape, palm and sole are the thickest, and the armpit and face are the thinnest, with an average thickness of 0.5-4.0 mm. ..

Although the thickness of skin varies from place to place, it can be divided into epidermis and dermis, which are connected with deep tissue through subcutaneous tissue. Skin color varies according to race, age and health. There are dense grooves in all directions on the skin, which are called skin grooves. The rhombic or polygonal ridges with different sizes between the skin grooves are skin ridges, which form fingerprints at the fingertips.

Fingerprint morphology varies from individual to individual, so there are individual differences in fingerprints. There are hairs with different lengths and thicknesses on the skin. There are nails and toenails at the ends of limbs. Skin can secrete sweat and sebum, which are secreted by sweat glands and sebaceous glands.
