How can I maximize barrier support?

Mine is so so so damaged, I am also limited to using fungal acne safe products because of seborrheic dermatitis on my face and scalp (honestly surprised my skin doesn’t react poorly to the Tula cleanser. Used to use Vanicream’s Gentle Facial Cleanser but it wasn’t helping the acne I was experiencing in that point in time (and perhaps the other products I was using as well, since it was a whole diff routine than this one here). At its worst, flare ups can look similar to psoriasis with plaque-looking skin build up. It traps hair and can cause ingrowns and infected hair follicles, it’s wild. If I use the proper combo of products in my routine, I can typically clear it up within a day or two but nothing ever lasts. I try to switch things up and it’s always a hit or miss, even when they’re 96% considered FA-approved :( Any tips on repairing my skin’s barrier, without the ingredients being Malassezia fung / yeast irritants… but also actively fighting weird hormonal acne (benzoyl peroxide has worked best)?! Ugh lol. I would greatly appreciate your advice! Thank you so much ♡
