Dynamic wrinkles such as crow feet, forehead lines and frown line are caused by muscle  movement. BTA (commonly known as BOTOX) relaxes the muscle and reduces the wrinkles. Static  wrinkles are due to aging and collagen loss. They can be improved by new collagen  stimulation. However, very deep wrinkles and folds can be filled up instantly with dermal filler.
