4 weeks ago I had C02 laser done under my eyes. In the past week I've had some pigmentation start to happen (yes I've been carful with sun and using sunglasses/sunscreen) I was recommended by my doctor to use hydroquinone 4%. On my first night of using it I noticed in the morning the spots got darker. My questions are...Is this the best product to use? When using hydroquinone does it get worse (spot get darker) before it looks better (lightens)?
