Wrinkles are caused by repeated muscle movements of the face, including fine lines, dynamic lines, and static lines. 1, fine lines: also known as dry lines, mainly due to local skin dehydration, small muscle movements lead to tiny wrinkles. 2, dynamic lines: when doing certain actions, such as laughing, lifting, opening the eyes, beating the mouth and other actions, the pull of large muscles lead to the local formation of facial lines. 3, static lines: like folding paper, repeatedly folding the same place, the paper in this place will appear obvious folds. . 3, static lines: like folding paper, repeatedly folding the same place, the paper in this place will appear obvious folds, this is the principle of the formation of static lines, long-term repeated muscle movements lead to the local irreversible creases. When dynamic lines or static lines are formed, Botox injections can be done appropriately to relax the muscles, which can improve dynamic lines and static lines. Fine lines mainly reflect the lack of water in the facial skin, so you only need to pay attention to daily hydration and sun protection to achieve significant prevention.
