Hello,
Light therapy will take a while for it to work but it's nearly proven in most cases to work. I've never taken Light Therapy so I can't comment on the situation.
That being said, if you are starting to peel and flake, you might wanna consider bathing also. There's many of things you can add like Olive Oil or Aalgo's Seaweed which is the same properties as the dead sea. It's used to help with Psoriasis and take about 2-3 weeks also to really get rid of all the redness, that being said, theres alot of treatments in the same time you can be doing.
You have probably been advised to take Emollient and I advise you take this heavily seriously. The amount of people that have Eczema and don't put on enough Emollients is shocking and I was one until I wised up. You have to put on shed loads at the start of the day and night but whilst during the day, your not so bad, so after a bath and about to go to bed, shed loads on, afterwards, just get a small tube but keep putting it on, can't stress this.
Your Diet is important as hell so you need to make sure you are getting EPA,DHA and GLA. Vitamins A-D-E are present if you take COD Liver Oil and Starflower Oil. The Liquid forms end up cheaper and have a higher % concentrated also so try your best and take it. I actually physically put it on me via capsules. 2 capules on the arms. I just pierce the capsules with a pin and then slowly put it on, might smell but I did this years ago to my hand with my mother and it's never came back, so there clearly some magic there.
There's alot more you can do and i'll be updating my side regarding everything i've said here plus more. It's found at
