Presumably

The reason why my face is spotty is because, either having too much margarine or coffee. And also, basically I have too much oil.

After I woke up in the morning, my face condition is quite calm. Not rough.
However, as time goes by it changes. Especially, it tends to appear at evening.

So, I decided to keep away from margarine and converted to a little bit of butter. And trying to drink tea. Today, I bought a pack of chocolate but, doesn't taste good. I need to look for tasty and not expensive green tea.
