Retin-A: Is this normal purging? (Photos)

Hello, I’ve been using retin A .0025% for 4 weeks now... I started with every night but decreased the frequency to every other night until I only do it 2x a week now because of the excessive dryness/skin sensitivity/itching. But I’m just wondering if this is normal or should I stop using it. Im really really desperate and conscious because my work requires me to meet with people but it seems like they’re so focused with my blotchy/dry/red/flaky face.
