3 Months on Accutane - Never really got Totally clear skin yet. Been getting 2-3 zits here & there?

I've been on Accutane for 3 month's exactly, First 2 month on 40mg/day & 60mg/day for last one month, my weight is 66kgs. Throughout the 3 months I haven't yet got a clear skin as I was expecting, I keep getting 2 to 3 acne here & there on the face specially after completing 3months I've had a breakout suddenly, when things were starting to look better, it went hay wire again.Is this normal? Is my Matte Sunscreen causing me to break out ? Also the redness, how do I minimise it :( ?
