Depending on the patient’s skin type and problems, I would most likely recommend the Obagi Skin Care System as this is one of the more aggressive approaches for skin rejuvenation and maintenance. I would have the patient on the Clear, which has hydroquinone in it. I would also recommend the use of Retin-A on a daily basis of tolerated. It is recommended that the patient discontinue the Retin-A and hydroquinone two to three days before the intense pulse light treatment and then they can resume it the day after the treatment again. Obviously a very good sunblock on a daily basis is expected of patients so that their skin can be rejuvenated to the highest degree and they will maintain this rejuvenation with the help of the sunblock.
