What causes wrinkles and fine lines that appear all over your face, adding numbers to your actual age and making your look tired and old? Aging skin is one the key reasons to why wrinkles and fine lines form. Aging skin, which happens to everyone, droops and develops wrinkles, fine lines and furrows. The severity of these aging skin changes in an individual depends on genetic tendency, skin phototype and exposure to environmental factors. Facial wrinkles and fine lines form because of the following factors: aging process, sun damage, muscle movement, smoking, and gravity. The main culprits are sun damage due to sun exposure and exposure to environmental toxins such as tobacco smoke.

FINE LINES AND WRINKLES ARE CLASSIFIED IN 4 DIFFERENT GROUPS:
Mild (few wrinkles, requires little or no make-up for coverage)
Moderate (early wrinkling, sallow complexion, requires little makeup)
Advanced (persistent wrinkling, skin discoloration, broken blood vessels and sun damage, often requires make up)
Severe (severe wrinkling and furrows, sun damage, requires make up but it may not hide the aging changes)

There is often a degree of asymmetry to the lines, as people tend to smile or frown more on one side than the other, or consistently sleep on either side of the cheek. Wrinkles and fine lines arise because of irregular thickening of the dermis and because of a decrease in the amount of water held by the epidermis.
