AMAZING. I can't believe I waited so long to purchase this! It was definitely worth the investment.
As of this review, I've been using the Mia 2 (Acne Clarifying) for 3 weeks. In terms of my facial skin, I do have combination skin (mostly an oily T-zone, with my cheeks and eyes having dry skin) with a history of mild eczema. Currently, I have been using Clinique Acne Solution and their Moisture Surge. With this purchase, I have been using the Clarisonic cleanser it came with and Philosophy's Clear Days Ahead.
From the first use, my face felt incredibly soft. A week into using it, I noticed at how my facial cleansers were being better absorbed and that I didn't have to use as much as I have been before. As a result of that, my face hasn't become too dry after washing and I don't have to put as much moisturizer (Clinique's Moisture Surge) afterwards.
My pores have become less visible and my blemishes have gone down a bit. Because of that, my make up has also gone on more smoothly on my face.
Again, it has only been 3 weeks, so I will update this review in about a month or two - when results will be more visible.
