My son is 4 years old and has Icthyosis Hystrix. It is a form of EHK. We have been using Tazorac on the neck to control the "dirty" appearance. I received this tip from another posting and decided to give it a try. I am really seeing some difference. It has really lightened his neck and also has thinned some of the other areas on his body. Has anyone else tried this? I would love to hear of others experiences with this. What strengths of the cream and how often are you using it? Also, have any of you found anything else that works similar to this? Hope to hear back soon. Kristi Hawk
