Could herbal teas cause breakouts?

Acne: Herbal tea is an expansive and generic term. I have no idea what herbs you ingested. Was it the very first time you had this kind of tea and you broke out soon after? If you see a pattern of skin breakout with any food item, you are likely sensitive to that food and need to avoid it, but normally "herbal tea" will not cause hyperandrogen state or hyperkeratosis which lead to comedone formation.
