the outer skin layer in human body is called epidermis.
what is the outer skin layer in human body called?
epidermis
pva can be characterized by speckled, combined hyper- and hypopigmentation in the plaques or patches of affected skin. hyperpigmentation is excess coloration, or darkening of the skin, while hypopigmentation is a diminished or pallid coloring to the skin. pigmentation changes in pva, apparent in the epidermal (outermost) skin layer, may be attributed to incontinence (leaking out) of melanin from melanocytes into the dermal skin layer below. inflammation of the skin and cutaneous tissue, common with pva, also contributes to color changes in the skin, typified by redness. telangiectasia, the visible "vascular" element of pva, is the dilation of small blood vessels near the skin surface. skin atrophy, a wasting-away of the tissue comprising the skin, is a prominent part of pva and effects the dermal, and particularly the epidermal layer. this, in part, is the result of degenerative liquefaction of the stratum basale (bottom cell-layer) of the epidermis. atrophy of the skin gives it a thin, dry and wrinkled appearance, which in pva-affected individuals has been described as "cigarette paper". hyperkeratosis, a thickening of the stratum corneum (top cell-layer of the epidermis), has also been reported.

thanks to her genetic structure that is a hybrid combination of plodex and earth dna, marrina's body is totally amphibious, and she has pale yellow skin, large fish-like eyes, and webbed hands and feet. possessing both lungs and gills, she can breathe and exist indefinitely on land or under the sea. she is able to withstand freezing temperatures and underwater pressures without harm. her hydrodynamic proportions, sleek skin, webbed extremities, and superhuman strength aid in her swimming. she can sustain underwater speeds approaching 51 knots (roughly 59 mph) for several hours and is capable of massive acceleration by shedding the outer layer of her skin to expose a nearly frictionless inner skin layer, allowing her to briefly reach speeds in the range. she has further demonstrated some ability to control water — in combination with her massive underwater speed, she was able to raise and ride the crest of a huge waterspout, letting her travel from an ocean shore up to three miles inland. after such feats, her outer skin layer can quickly regenerate to normal. her skin also secretes an oil which can cause extreme constriction of the pupils — with one slap, she was able to temporarily blind the sub-mariner, himself superhumanly adapted to underwater existence. on dry land, she can sprint at tremendous speeds.
