Is there a way of fixing or touching up damage to varnished wooden surfaces?

I accidentally spilled perfume on the surface of my beautifully varnished wooden coffee table. Over the period of a few hours, the areas containing the spilled perfume have removed the varnish.

I have looked all over the internet and have been unable to locate a spot treatment varnish or similar product.

Is the only solution to restoring the finish stripping it all back, sanding it and applying new varnish?
