Hi! I'm applying the green tea toner and serum for oiliness. I'm on 5 mg per day isotretinoin to help manage seborrhea as well. I also have the hyaluronic watery essence. My concerns are dilated pores and very mild seborrhea, but as far i can see, my routine lacks hyaluronic acid. Could you please help me suggesting the best IsNtree products combination? Maybe it could be a good choice replace the green tea toner by BHA 2% toner, as it has 3 types of HA in it, there is recommended to use the green tea serum after. Thank you. And please consider shipping to Argentina!
