Most people think wrinkles are cause by dry skin, sun damage, and age. These are all contributing factors, but the real cause is facial expressions. Since we know what causes wrinkles, it's easier to determine an effective cure. Because we know that wrinkles are not caused by dryness, we then know that wrinkle creams are not the answer. Wrinkle creams hydrate and sooth dry skin. Depending on their ingredients, they can also lighten dark spots, help exfoliate, protect from the sun and provide valuable nutrients. But wrinkle creams cannot smooth out deep wrinkles cause by repeated facial expressions. Only a physical (mechanical) counteracting of the damage done by these repeated impressions can undo wrinkles. Only an actual mechanical smoothing of the skin can change the contours of your skin.
