I am a 54 yr old African-American female who has severe hand & foot eczema for the past 10 years , I also breakout if i am in the sun (was not born with it ... did not have it as a child). Over the years i have tried everything creams, steroids , phototherapy etc etc..nothing worked. My first dose of Dupixent was July 23rd and every 2 weeks after that. I was expecting to see improvement of my skin and less itching by now, except for the skin not thickening anymore i am still itching like crazy and no clearing of the skin yet. Skin still ugly and itchy... please ... how long does this medication to work? Trying to be patient but does it work for all types of eczema? I only have it on my hands and feet, the rest of my body is clear. Awaiting an answer. Thanks.
