Hello ! I guess you should apply the gradient tool to the text and duplicate the layer. It will give a nice shine to it.. You can also toogle with gradient to get your desired results. Best of Luck
And yes I forgot to mention that you can also apply the outer glow and change its setting to set it right according to your requirements.
