I don't do too many things really. My skin is usually good, but is very sensitive so I have to be careful (when it's cold, etc).
I don't use water on my face, I try to avoid it. I just clean my face with a water cleanser once or twice a week (once in winter, twice in summer). Otherviwe, just an Avène cleanser and moisterizer.
I drink a lot of tea, I think that's why my skin usually looks nice.
I try not too touch it otherwise (like, scratching my face with dirty fingers when in the bus!), I just leave any spots and don't treat them. They never last more than three days if I ignore them!
