accept the mask at its current setting and create a selection in which you cannot see the edges.

Remove fringe pixels from a selection
When you move or paste an anti-aliased selection, some of the pixels surrounding the selection border are included with the selection. This can
result in a fringe or halo around the edges of the pasted selection. These Layer > Matting commands let you edit unwanted edge pixels:
Color Decontaminate replaces background colors in fringe pixels with the color of fully selected pixels nearby.
Defringe replaces the color of fringe pixels with the color of pixels farther in from the edge of the selection that lack the background color.
Remove Black Matte and Remove White Matte are useful when a selection is anti-aliased against a white or black background and you want
to paste it onto a different background. For example, anti-aliased black text on a white background has gray pixels at the edges, which are
visible against a colored background.
You can also remove fringe areas by using the Advanced Blending sliders in the Layer Styles dialog box to remove, or make transparent, areas
