From a non-believer to a constant user and now trying out the "7 Skin Method" trend, Toner or Skin as known in Korea or Lotion in Japan has been constant in my skincare routine.
In my younger years, I always thought that a toner is either very strong to the point of burning the skin or as bland as water packaged into a fancy bottle. As I got to skincare, I learned (and still learning) that a good toner (or Skin in Korea and Lotion in Japan) can restore the skin's pH balance quickly and prepare it in your next skincare step and provides extra moisture and nutrients thus helping in repairing the skin's protective barrier (and so much more depending on the ingredients of your toner).
