There are wrinkles in the corners of the mouth when playing cucurbit silk.

It is a normal physiological phenomenon that wrinkles appear at the corners of the mouth when playing cucurbit silk, which has nothing to do with the instrument itself. This phenomenon may be caused by muscle fatigue or excessive facial expression. Playing musical instruments for a long time may exercise facial muscles, which may lead to wrinkles.

However, this does not mean that blowing gourd silk will directly lead to the formation of wrinkles. In most cases, excessive tension or long-term tense expression, such as frowning or squinting, is the main factor leading to the formation of wrinkles.

Therefore, if you find that blowing cucurbit silk will wrinkle the corners of your mouth, you can try to adjust your playing posture and expression, or take a proper rest to reduce muscle fatigue. In addition, maintaining adequate moisture and proper facial moisturizing can also help reduce wrinkles.

Please note that the above information is for reference only. If you have any questions or concerns about the formation of wrinkles, it is recommended to consult a professional dermatologist or beautician, who can provide you with more specific suggestions and solutions.
