This looks like chromatic aberration (color fringing). In Lightroom, the simplest fix is to enable the lens correction option labeled “Remove Chromatic Aberration” in the Lens Corrections/Optics panel. That often cleans up red or magenta/green fringes automatically.

If needed, you can then fine-tune with the manual defringe controls in Lightroom. In Photoshop, Adobe Camera Raw offers similar chromatic aberration removal tools.

For future product shots, stopping down the lens a bit and avoiding high-contrast edges near the frame edges can help reduce this effect at capture.
