My experience:
I decided to try retinoids after reading some of Frederiks posts here last summer. I've been using Tazorac .05%. So far my experience has been good, but one of the things I've noticed is that the skin condition doesn't simply keep getting better. It seems to get worse, then improve. Then it may worsen again, and then all of a sudden it will look amazing. Repeat ad-infinitum. Just as you're starting to enjoy the new radiance to your skin, some day you will wake up and your wrinkles will be more pronounced or your skin may be red and flaky, or tight. Then of course this will change again after a few more applications. The changes occur very quickly and skin appears to go from looking pretty bad (often red and sundamaged looking), to looking amazing literally overnight.
At some stages I was ready to give up, because I didn't like the fact that I my skin type seems to have changed from oily/combination to dry/sensitive. But then somedays my skin really does look amazing so let's give the retinoids a year and then make a decision.
I guess my question is; when does it level out? My guess is that after a year of usage, my skin will stay looking great and the bad effects will disappear?
Adjustment:
It took my skin a long time to adjust. For about 3 or 4 months I could only use it every second night, or every third night. Only in the last month would my skin accept it every night, and even now I still buffer every second or third night. The eye area became particularly sensitive to moisturisers and even my ultra light, skin friendly La Prairie SPF15 eye moisturiser would cuase a lot of redness and soreness on the skin under the eyes. I needed to change to a very sensitive cleanser and moisturiser. For washing/cleansing the face I use "kind to face" face wash: http://www.superdrug.com/invt/949388
And a moisturiser like this:

Other people:
Some people have said that my skin looks very good. My aunt mentioned that she thought I had put on a little weight on my face, and it looked better. Strange, as I've actually lost weight and I practice mild CR and eat a lot of raw vegetarian food. One person thought I was wearing face make-up, and that I had a very good, healthy colour and it wasn't like my normal pale look (this could be down to the raw food also)
Future:
At the moment I use a very gentle Oil of Olay sensitive skin moisturiser under my Biotherm SPF50 each day. Any other moisturiser seems to irritate the skin a little and make it red, especially around the eye area. But in the future I'm thinking of adding Ferulic C+E. I may also go back to using Anthony vit C serum, which gave me nice results before my retinoid use.
