Crows feet are skin creases or wrinkles, around the orbicularis oculi muscle area, and it is often the first signs of aging noticed amongst most women. They are caused by repeated muscle movement from smiling, laughing, and squinting. These include both the dynamic and the static wrinkles.
Dynamic Wrinkles occur with the formation of facial expressions. Example would be when you smile, your eye wrinkles become prominent.
Static Wrinkles are the folds and lines that are present even without forming facial expressions. They gradually form whereby the skin loses its elasticity and decreases in collagen production as we age.
