I had same conditions like yours for years also, according to my research, this is not a skin problem but might be a leaky guts, because I gave up already on topical steroid and drugs, they will come back again and again. I let you know if I got better from healing my gut from natural/holistic ways but maybe take up to 6 months or years. Need take more probiotics food and need to face a healing crisis on the healing process.
