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.

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!”

An eyelid twitch is a general term for involuntary spasms of the eyelid muscles. In some instances, the eyelid may repeatedly close (or nearly close) and re-open.This article discusses eyelid twitches in general.
Eyelid spasm; Eye twitch; Twitch - eyelid; Blepharospasm
Causes, incidence, and risk factors
The most common things that make the muscle in your eyelid twitch are fatigue, stress, and caffeine. Once spasms begin, they may continue off and on for a few days. Then, they disappear. Most people experience this type of eyelid twitch on occasion and find it very annoying. In most cases, you won't even notice when the twitch has stopped.
More severe contractions, where the eyelid completely closes, are possible. These can be caused by irritation of the surface of the eye (cornea) or the membranes lining the eyelids (conjunctiva).
Sometimes, the reason your eyelid is twitching cannot be identified. This form of eyelid ...
