I have not noticed any huge changes since last night, but my skin did feel much smoother this morning and i'm still only able to use it on the sensitive setting as it's very strong, and does leave my skin a little red afterwords. It does leave your skin feeling a little tight but that may just be down to my skin type (combo). I know most people tend to worry a little over your skin having a "purging" period, where your skin get's bad before it gets better but I can honestly say it's not something I have ever really experienced.
I am hoping for a noticeable chance in the clarity & texture of my skin but for now, I will leave you with a list of where you can buy this, as it's so widely available for a product of it's kind.
