SmoothKP routine question

At the moment my routine is moisturiser and SPF50 in the morning and then at night I use cleanser, then a 50/50 mixture of SmoothKP and moisturiser on my cheeks and moisturiser on the rest of my face. I can't see much difference at the moment and have been doing it like this for a few weeks. Is this routine worth sticking with or should I tweak it, for example including days where I don't use it or use it more potently? My KPRF is relatively tolerant and not that sensitive but nothing I have tried has reduced the baseline.
