Different Foundation Uses

I am currently switching between 2 foundations every other day.  For the days that 'matter,' I wear my Makeup Forever HD Foundation in #117.  For the days that 'don't matter' & I want to give my skin a rest, (my skin is very pale, sensitive, and acne-prone), I wear my Neutrogena SkinClearing Foundation.  I have found this to be very helpful for my face and for time's sake.  Do you switch your foundation routines depending on events?
