Fungal skin issues

Looking for people with similar experiences with face skin/ fungal issues. My diet is already very clean. Mostly animal based. Will have some potatoes, sometimes frozen fries time to time and fruit. Usually berries or bananas. Lately that’s been infrequent. I eat whole eggs, egg whites, beef, chickens thighs, salmon, milk, cheese, yogurt, preteen powder(mark bell steak Shake). My guilty pleasure is dark chocolate which is my worse source of sugar. Not a lot of veggies at all for last couple months. It’s been a wedding month in October, so “diet” wasn’t perfect. i am now off of alcohol completely. I run and lift weights daily. I am 5’9, 170 lbs. 15-16% body fat by Dexa.

I have had hormonal imbalances. Very low testosterone. For the last few years I’ve had some face redness, itchy skin patches on beard line/cheek line really. Some days are worse than others, I’ve also had some scalp dandruff issues. Head and shoulders helps that. Dermatologist prescribed an antifungal wash, but side effects are same(red itchy dry skin). It’s not comfortable. I also get pretty frequent fungus infections(on the dick after sex, but we’ve ruled my partner out). I’m assuming this is Candida or Malassezia? Has anyone had success cutting out sugar or dairy to cure this?
