Sensitive skin 3 - My skin needs a detox!

I learnt during my teenage years that I need to use face scrubs every week in order to get rid of the accumulated debris on my face! I was also told that I should exfoliate before I apply any type of mask on my face to absorb the nutrients better. I love using face scrubs once or twice a week, but too much scrubbing/exfoliation can damage skin and its ph level. So I discovered NeoStrata ph4 face wash 2 years ago. It is designed for a sensitive skin type, as well as post surgery type of skin. It is an oil-free and soap-free non-drying cleanser, containing 4% Gluconolactone ( a type of AHA). It gently exfoliates the skin to thoroughly clean the skin and to remove makeup. I only use this cleanser when my skin has little bumps underneath my skin. ( a sign of congested pores which could worsen and turn into spots!). I use this cleanser after I use my daily face wash. I massage it in a circular motion with wet fingers for 3 minutes. I use it continuously for 5 days and I can see and feel those little bumps disappear! It must have something to do with AHA which stimulate the skin cell renewal, therefore speeding up the exfoliation of the dull upper layers of the skin. My skin feels soft, clean and it mainly keeps all those spots away!
