I'm working on a short that has a plastic skin patch in it, but the edge didn't really stick to the skin, so long story short i need to make some gaps disappear.
Here is an image of it:
I've made a mask around the "scar", i've been trying many different blurs and color correction methods, sometimes 3 of them at the same time, but i just can't seem to find the right effect to use.
Here is an image of what i managed to accomplish so far:
Does anyone have any experience regarding this problem?

you may need to add hair to help disguise the patching.

here's a link to some photoshop brushes for hair that may help you... this would involve creating hair in photoshop and then adding it in ae, so some motion tracking may also be involved if either the arm or camera moves.

at the bottom of that article, there is also a link to some skin brushes that were used in the samples shown.

Cloning will likely give you a better result. Kevin's given you some options in PS to look into which are also useful.

All of the previous is great advice. My approach would be to create a patch in PSD that looks good and then apply that using tracking (Mocha) and match the grain. Of course we don't know how much the hand is moving or if the camera moves at all, in which case it becomes more complex.

I'd start with cloning, like Roland mentioned.

You might also be able to cheat a bit on this shot (or in this sequence) by color grading the left-most edge of the arm. Because the arm is curving away, I think you could throw it into shadow and have it still look realistic and consistent with the style of the frame. This wouldn't complete cover up the edge on the patch, but it would help to push the eye away from that edge and may be combined with any of the suggested approaches.

Thanks for the tips, I've tried some of them out.
It's definitely trackable, but the arm stretches and rotates a bit, so the photoshop method didn't work. I ended up using curves/channel blur/hue-saturation adjustments and a lot of keyframes.
