I have been using for about a year. It is an easy process and the price seems competitive with what you could get with Good Rx style coupons. One possible benefit isCurology offers slightly different concentration of Tretinoin - you start at .02%, then go to .035%, vs .025% and .05% for the typical generic prescription. So if you are sensitive you can ease in a little more slowly and perhaps use a regular prescription to ease up the curve more smoothly, rather than jumping up a big step. Another benefit is your provider will put two additional ingredients in the formula based on your issues - mine are niasinimdes and azealic acid. So you are getting a bit more bang for your buck.
I asked my dermatologist about them and he said they were fine. FYI, he told me once I had worked up to using the .02 daily to stay there for a long time and that it had taken his wife a year to move up from that to .05%. I wish I had listened - I have found that I tended to rush it too much and got a lot of irritation, even though I was trying to ease in. But my skin is super dry, fairly sensitive and going through annoying age-related changes. So I have started afresh and am re-easing in at a very slow level. I haven't seen dramatic results, but I'm using the lowest dosage and only every 2-3 days.
