I keep it very simple. I've been using a miracle worker auto delivery for the last couple years. It just ended, but I have plenty left. It had face wash, retinoid pads, and day cream. I basically just use that. I don't know the name if it, but once a week I use the scrub that you add the citrus liquid. They showed it yesterday. At some point I would like to add the serum. If I didn't have this kit left, I would have considered yesterday's TSV. I prefer to buy the kits if they make sense. Wasn't crazy about the super size, but I would probably deal with it if I was low on things.
