Purge or breakout

Hi there. After almost two all months I’ve been using Retinoid, my face started to become red in the day, and now I have this constant break out of little yellow acne where I use to have acne before. My skin is thinner and absorbing every product. Before really helped my skin/scar which now is a mess. Should I stop or is just purging? Can it start purging after so long? Also I have extremely sensitive skin.

Thank for your time

Have a lovely day
