I've been doing the spearmint thing for a while now so I can comment that I can definitely see a difference in my skin. I'm still breaking out but my skin is MUCH less oily. It was so oily to begin with that it's still a bit slick on my t-zone by the end of the day, but compare that with looking like my whole face was covered in Crisco by 10AM. I've also switched back to a moisturizing bb cream and to my less drying cleanser because my chin was starting to peel from dryness!
My zits have also been all pustules rather than cysts (knock on wood!) for the past few weeks.
I am running out of my spearmint stocks though and don't know where to find it here...might be an Amazon item.
I'm trying to only add one thing at a time so I can see the effect, so starting this week I am adding supplementation: zinc
so we'll see how that goes!
