Origin: From epidermis, from ἐπιδερμίς (ἐπί, on top of) + dermis (< δέρμα(derma), skin)
the outer, nonsensitive layer of the skin; cuticle; scarfskin. See Dermis
the outermost layer of the cells, which covers both surfaces of leaves, and also the surface of stems, when they are first formed. As stems grow old this layer is lost, and never replaced
Origin: [L., fr. Gr. ; over + skin, fr. to skin. See Tear, v. t.]
The epidermis is composed of the outermost layers of cells in the skin, "epi" in Greek meaning "over" or "upon", which together with the dermis forms the cutis. The epidermis is a stratified squamous epithelium, composed of proliferating basal and differentiated suprabasal keratinocytes which acts as the body's major barrier against an inhospitable environment, by preventing pathogens from entering, making the skin a natural barrier to infection. It also regulates the amount of water released from the body into the atmosphere through transepidermal water loss. In humans, it is thinnest on the eyelids at 0.05 mm and thickest on the palms and soles at 1.5 mm. It is ectodermal in origin.

So far we've got interesting results from three astronauts. It seems that there is a strong production of collagen; so suddenly these astronauts have more collagen. It means there is some sort of anti-ageing effect, at least in the dermis - the lower part of the skin. And we found that the epidermis, in particular the part of the living cells, that this epidermis is shrinking, so the skin gets thinner, so far we have no explanation yet, and we are waiting for the other astronauts to figure out what's going on and maybe to try to figure out how we can protect, how we can help so that this epidermis is not shrinking.
