Editorial review provided by VeriMed Healthcare Network on April 18, 2005. Wrinkles are the thin, creased, and sagging skin that is especially noticeable on the face, neck, and hands. Wind, heat and chemicals and the natural effects of aging cause a certain amount of wrinkling in everyone, but it is much worse in people who spend a lot of time in the sun. Years of exposure to the sun cause "photoaging," which includes freckles, yellowing, roughness, visible blood vessels, and dark spots, as well as wrinkling. Years of sun exposure cause the supporting structures of the skin, primarily the collagen and elastin, to weaken and break down. In addition, as a person ages, the sweat and oil glands of the skin become less numerous and smaller in size. This causes the skin to lose moisture and to dry out. Dry skin with weak collagen and elastin will...

Kayla writes , “I have white spots that are spreading from my neck, back, arms, chest and belly…help me.”
Chic writes , “I have a small area of white skin under my lower eyelid…HELP!”

A drooping eyelid can stay constant, worsen over time (progressive), or come and go (intermittent). It can be one-sided or on both sides. When drooping is one-sided (unilateral), it is easy to detect by comparing the two eyelids. Drooping is more difficult to detect when it occurs on both sides, or if there is only a slight problem.
A furrowed forehead or a chin-up head position may indicate that someone is trying to see under their drooping lids. Eyelid drooping can make someone appear sleepy or tired.
Drooping lids are either present at birth (congenital) or develop later in life. A drooping eyelid is not a reason to panic, but you should report it to your doctor.
Drooping eyelids may be due to a variety of conditions include aging, diabetes, stroke, Horner syndrome, myasthenia gravis, or a brain tumor or other cancer t...
