I have a question regarding Hydroquinone. I asked my dermatologist about the dark circles under my eyes and also a few brown spots I had. He recommended 8% hydroquinone in 0.01% retisol, to be used twice a day. I am finding that it seems to make my skin more sensitive and I have been getting these red itchy spots. Will this pass or is this product maybe too strong. Any recommendations for these problems that may be better than this. I am 54 years old. Thanks
