Singapore and Eczema - Recommendations Required

Hi everyone, I've been living in Singapore for more than 4 years and suffered most of my grown life from Eczema. The key challenge for me is that my Eczema has never been worse as it is today. The escalation started 18 months ago, and I got to a point that 11 months ago I've started with Dupixent. I'm paying it from my own pocket and I must say I have not seen improvement as I thought.

I am considering to stop using it and looking for advice: 1. I know that nutrition could be a key part, which in the last 12 months I changed a lot. Does anyone have any recommendation to nutrition who specialized in Skin condition? Base on personal experience please. 2. I have not changed our laundry detergent. It is time to do it... What are you using for sensitive skin? 3. I have not done lately allergy test. Should I just ask my GP to refer me to blood tests? 4. I tried in the past TCM but for very short time. Does anyone have good expirence with TCM especially for Eczema. Can you recommend?

Btw, It could also be the weather, I did realise that lately I've been in my home country for few weeks and I felt that my skin is much better.

Thanks everyone
