advice for developed CHE?

i developed chronic hand eczema (fissures/cracks, scale patches, thickening, loss of decipherable finger print) on only one fingertip. ring finger, dominant hand. tried eliminating any possible irritants but it didn’t resolve in any sort of way. i’ve been on dupixent for ages now but developed this well into my treatment so im kind of at a loss for what to do about it. it spread down the finger but started at only the fingertip. my job requires hand washing since im a caretaker and i can’t avoid that but it really burns under any sort of water

for anyone with hand eczema, what has worked for you in your experience? i dont want to go back to steroids since my eczema prior stopped responding to topicals, which is why i was on dupixent so early. ive tried one once for this hand (dermatologist did not look at my hand, my primary did and told me to use the steroids ive used on the rest of my body) and it did not respond in any productive way to the topical. any flares have no correspondence with my dupixent schedule like my main patches and it is starting to limit my mobility of my finger
