Discoloration

I’m considering IPL Laser or Hydroquinone to even out my skin tone…Anyone have advice?

I’m already using the Vanicream Vitamin C (my skin is very sensitive) and Retin-A 0.025% 2x/week. I also use a skin brightening serum with niacinimide, arbutin, and kojic acid. And mineral SPF every day. The discoloration has improved, but looking for even more improvement.

Anyone have thoughts on IPL vs. hydroquinone? Or any other ideas to recommend?
