Reducing redness appearance on chin-routine advice? - azelic acid

Currently use a cetaphil combination skin cleanser, i use cetaphil spf50 with moisturiser and vitamin c from cerave in the morning. At night i put on isotretinoin 0.025%. I was wondering if to add azelic acid not sure if skinoren 20% or finacea 15% and if i do add it if to use it in the morning with the spf50 and vitamin c or if to use it at night with the retinoid? I just want to reduce the red looking appearance especially on my chin and jaw? If anyone has any feedback on my skin care routine how to improve it let me know.
