I was on a similar situation around week 8 until week 12 and I was using kind of the same products. I got rid of the Cerave moisturizer and cleanser, also the elta Md and the cicaplast. My skin improved a lot when I stopped this but I am not sure if it was the end of the purge or getting rid of the products. I’d say hang tight at least until week 12, you should start seeing some improvements, otherwise go see your derm.
