New foam treatment called ESTILAR. Advised my granddaughter to go to GP and get script, which she did. But not before a bit of an argument because of cost, my granddaughter has had all the creams, potions and ultraviolet with very short term improvement. She is only nineteen and psoriasis has been hard for her to cope with, she refuses to take meds that can affect pregnancy, even though she's not pregnant or contemplating motherhood yet. Her argument is how long do these medications stay in your system and do they know if it could affect fertility in the future. Obviously, the doctor was not happy and virtually wrote her off, NOT GOOD ENOUGH. Anyway she has started the Enstilar and reports improvement after just two weeks. Fingers crossed everybody.
