No! Magnesium is an electrolyte, and good for sleep and muscle/neuron function, but eczema is a deeper condition, can’t be cured from above. IMO, not a doctor.

Eczema is going to be a dietary manifestation. Some food you don’t tolerate well, that you’ve been eating over time.

For the outer manifestation, I’d highly recommend LuSa Organics Da Balm. Excellent, high-quality, infusion-based balms made for over two decades. It WILL help with outer expression of whatever is triggering your eczema (from what I believe is dietary). Not a doctor, just someone who appreciates you and trying to help.
