Hydrating toner/essence that is safe for pregnancy and seborrheic dermatitis?

As the title says! I'm looking for a toner or essence that is safe for pregnancy and also seb derm. Ideally something that is cost friendly so I can continue to purchase it if it end up liking it. Maybe something I could put in a bottle and spray on my face during the day? Does such a thing exist?

I do have a history of seborrheic dermatitis and don't want to use something oily. It had pretty much subsided, and then pregnancy hormones have made my skin react again. Though I must say joining this sub has helped. :)
