lb17 probiotic paste

I was looking at lb17 probiotics and I saw that it also comes in a paste. Does anyone know if applying the paste directly to the skin would help Seborrheic Dermatitis . I think one of the reasons my skin's messed up is from using proactive and prescription Antibiotic creams for acne, and if oral Antibiotics kill friendly bacteria on the inside would I be correct in assuming topical Antibiotics killed the good guys on my skin and aided in the overgrowth of fungus on my face? I've already tried lots of topical antifungals like tea tree, neem, and coconut oils and they didn't help. Tweet
