HG Toner
A toner that is very gentle to my sensitive skin and keeps my face hydrated throughout the day.
It's VERY good at keeping hormonal acne away and dark spots, but it is SOOO drying. I have really oily skin and using this product in 1 week gave me dry patches around my cheeks, jawline, and chin area that has never come up before in my life.
I've only started using this toner 2-3 times a week, because using it everyday can have worse effects than good ones.
