New School Solutions--Clear + Brilliant, Microneedling/prp and lightening
I recommend a combination approach to help this. I typically use clear and brilliant laser and/or microneedling/prp in combination with lightening creams to help with pigmentation. See an expert. Best, Dr. Emer.
Hydroquinones and Retin-A
If you are exposed to the sun it is possible that the pigmentation is coming back. I would recommend cycling the bleach with other creams that are effective but do not contain hydroquinone and then re-introduce it again after a few weeks. A chemical peel would also help a great deal at this point. Best, Dr. Green
Cycling hydroquinone and Retin A
The newest recommendation from Dr. Obagi is to cycle the hydroquinone and retin A. It doesn't mean stopping the use of products but change them out. There are several non hydroquinone products in the ZO line that can be used and retinol can replace the retin A. If you don't see the effects you like with the swap, go back onto the original products. The feeling by Dr. Obagi is that Retin A can leave the skin chronically inflamed and that Retinol is better tolerated by most. Also, hydroquinones can have a rebound effect when stopped and also make people more sensitive to the sun. Also, overuse has been shown to be detrimental and cause ochronosis. The theoretic carcinogenic effects of hydroquinone have never been seen in humans.
