First, not using the expression muscle for a long time will accelerate the degradation of the orbicularis oris muscle, leading to drooping corners of the mouth.

Therefore, when we work for a long time, we should take time to relax our facial muscles and smile more every day.

Second, with the increase of age, the loss of collagen will also lead to drooping corners of the mouth.

Pay attention to a balanced diet and eat more antioxidant foods, such as tomatoes and grapes. Drinking red wine and tea in moderation can also protect collagen in the skin.

Don't blindly diet to lose weight and avoid eating fatty foods. A proper and balanced diet is good for our health.
