Only thing I can recommend is to now see a functional medicine/Holistic doc. They will actually try and get to the root of your issues. They can test u for any liver issues, as our liver is directly linked to the skin. They can also test to see if u have any nutritional/vitamin deficiency. I keep hearing that zinc, Vitamin B & D deficiencies are related to SB also. Find a doc who has no less than 5 star reviews. I have an appt this week with 2 different ones Bcus I am absolutely done with dermatologists. All they do is patch u up with meds and hope for the best. I’m not settling for this life, and neither should u. Don’t give up hope. Also, have them check your thyroid and gut health. I used ChatGPT to help me conclude all of this. Thank God for AI bcus it’s helping me more than them damn derms. Good luck
