Mouth protrusion may be caused by many factors, such as lens angle, light, mouth shape and position, lip texture and expression. So, if your mouth is not prominent in reality, but it looks prominent in photos, it may just be caused by photography or photo editing.

To reduce this influence, we can try to adjust the shooting angle, adjust the light, pay attention to the shape and position of the mouth, relax the lips and so on. If you are not satisfied with the effect of the photo, you can also use photo editing software to adjust the shape of the mouth in the photo to make it more in line with your real appearance.

In a word, photos are an art form and are often influenced by many factors. If you are not satisfied with your photos, you can try to adjust the shooting angle, light and other factors, or use photo editing software to improve the effect of photos.
