Green tea was one of the first ingredients I looked into when I figured Niacinamide and I will always have a rocky relationship. It's supposed to help with sebum production and it really does just not as well as Niacinamide. I also found this product very moisturizing, right now where I live is going through a cold spell and that would usually have my face feeling dehydrated by mid-day but with this moisturizer, it actually leaves my skin plump and hydrated looking for about 6 hours(I’m currently jobless so yh I timed it).
