How effective are wearable accessories using infrared LEDs for disrupting facial recognition?

It's not something you would be able to rely on all the time. Security cameras that use IR to see in the dark could be blinded by IR LEDs, but cameras can also have IR filters.

Would something retro-reflective be a better solution?

That would only be effective on cameras that use active lighting to see, and image sensors have become increasingly sensitive to the point many can get a lot of definition in very low lighting conditions.

You're better off looking at solutions that fool facial recognition algorithms through the use of intense colors and patterns, like this line of clothing.

This is sadly very noticeable.

Yep.

And there have been examples of camera disruptive devices that use IR and while it can work, it's problematic and inconsistent.
