Yes
the skin's elasticity
dehydration
Collagen
Yes it does. Loss of interstitial fluid is the same thing as dehydration. And that loss of fluid makes the skin less elastic, when you pinch it, it does not spring back as quickly.
Gravity and the loss of elasticity and adipose tissue in the skin........which naturally happens over time...........
Stretched out skin can indeed gain some of its elasticity back. Stretched out skin will never have the full elasticity it once had.
permanent redness, loss of pigment in the skin, and breakdown of the collagen that maintains the elasticity of the skin
As aging progresses, wrinkling is due to a few processes, most notably the loss of collagen and elastin in the skin, resulting in a lower tensile strength. This is made worse my lack of moisture in the skin, exposure and especially sunburn, stress, smoking.
The aging process and the cumulative effects of sun, gravity, genetics, and other factors cause a loss of skin elasticity, which leads to sagging, lipoatrophy, and other loosenings of the skin and facial structure
Vomiting, diarrhea, biting tail and legs. Also something with the eyes, not too sure. Also, loss of skin elasticity due to dehydration
of your crack
Yes, for some disease though. Not all diseases have a symptom of skin rashes. Have your doctor inspect it and see if you have a disease.
