There is a shadow on the right side of the face. It's too dark. Please help me brighten it. And the shadow on my lips is so ugly, like a beard. Trouble god p off.

This problem is mainly due to poor lighting. The right side of the picture is too bright and has been overexposed. In order to take care of the right side and prevent it from being brighter, the left side of the picture is dark. The overall light of the picture is still too strong, but it is very clear, the eyes and pupils are well shot, and the facial contour is also very clear, so the contour will be worse after adjustment.

The following one is a compromise. Choose which one you like.
