Duplicate this layer and blur it even more (Filter > Blur > Gaussian blur with radius of 7px) and change copy's blending mode to Color Dodge.

Then just do exactly the same on the opposite side.


As it is brighten part and thus more reflective, we can make this layer a bit brighter with Image > Adjust > Brightness/Contrast.

But here instead of Color dodge, copy could be leave with Normal blending mode

Create new clipping layer. Remember our strategical layer? [CTRL] + Click on 'Shape 1 copy' thumbnail so you will get a selection. We have used it to simple shadows and now it will help us with lights. Pick the color #f8eceb.

Get Gradient tool and make some gradients from bottom to top.
