Photoshop help removing abdomen line from skin texture pls!

So here is what the area looks like in photoshop unedited - the problem is if I just blend it in it makes the middle of the texture very whitish bloomy because I was basically blending the middle area "out" with "whitish" area around the center line.

What I think needs to be done is a more blended approach like my screenshot edit where their is a mixture of shading to represent the skins central abdomen without just using a hard line as it is now.
