Tretinoin and rosacea skin. (photos)

Hi, I've been using tretinoin 0,05% cream, once a wk for the past 3 wks. I think my skin had rosacea before. These are the photos of my skin now. I used it 3 days ago, and it was the third application I had. I see those red bumps, my skin used to be flawless, just slightly pink on the cheeks. Should I stop now? I was planning to use tretinoin for the winter season, starting once a wk for 3 wks, then 2 times a week for another 3 weeks etc till reaching the use of it everyday, around the week 20th
