Experiences with using LRP Effaclar Duo + as a spot treatment, or can I better buy an other product?

Hi! I was wondering if anyone uses or has experience with using LRP Effaclar Duo + as an spot treatment!

I have mild acne with quite a few of blackheads on my nose, sometimes a few breakouts. I have most of the time flushy cheeks/mild rosacea. I have also some back acne, and I want to use the LRP Effaclar on my back too.

I'm considering using the LRP Effaclar with the Cerave 2% SA Cleanser (once a day) , I also use The Ordinary 10% Azelaic acid three times a week, but it looks that it doesn't really do anything to my face.

If you have any other alternatives, let me know! Thank you! :)
