Interesting about the vitamin A. A topical prescription Vitamin D3 topical is Calcipotriene Cream or Dovonex and has helped me. Developed to be primarily used for plaque psoriasis it seems to stall my GD breakouts. If already broken out it keeps the breakout from getting worse. Very expensive and I was better buying it with GoodRx the free coupon site on the internet than my Humana Medicare Pharaacy supplement. 60 gram tube without insurance around 300 but with GoodRx paid 100, yet it lasts. Even though the torso is a large area to cover it spreads well and takes very little. GD is baffling, as it comes and goes even when it seems the typical triggers have been avoided. AS I tell all, go to dermnetnz.org, best eczema site for less common forms of dermatitis or eczema like GD. Have been in remission now for almost 6 months, my longest break and only use the Calcipotriene about once every week or 2 if I start to feel a tingle and bumps beginning to form. Also believe my candida detox is helping all my eczema issues, (I have 3 forms), as residual candida in our intestines raises our histamines. No candida issues now after 6 weeks of detox and on maintenance plan. Basically zero processed sugar for life, no natural sugar as in fruit for 2 months and then only add back a few pieces a week.Zero carbs for 2 months and now can have small servings of non gluten carbs a few days a week. I feel fantastic and surprisingly to me, after 6 weeks of detox the candida symptoms disappeared along with my sugar craving. Yes sugar is an addiction and although my diet wasn't heavy in processed sugar, just a normal amount, I ate way too much fruit. At least 3 pieces a day and fruit is loaded with sugar. This sugar fed my candida residing in my intestines. Now it is killed because it starved to death. While dying it sends stong messages to our brain to be fed! An addiction just like nicotine or alcohol or other drugs. It will be interesting to note when my next break out happens with GD, as I know it will, but hoping this stalls the breakout longer.

Sorry to hear your husband is dealing with this. Interesting about the Vitamins. I was just diagnosed summer 2018. I did have a short lived “remission” but have been dealing with it consistently since. I’m a 46 y/o female, no health conditions, no medications, not over weight, no food allergies... this just came out of no where. I am an RN and have likely been exposed to lots of things - but there doesn’t seem to be any sort of external link. 🙁 I will gladly share any wisdom as I venture down this road. Best wishes!
