Question about retin-a

Does Retin-a help reduce oil production from the skin? since isotretinoin(active ingredient in retin-a) can be found in accutane (accutane is known to reduce oil containing tretinoin).

Oh, and whats the difference between isotretinoin and tretinoin?

Tretinoin is all-trans retinoic acid, and isotretinoin is 13-cis retinoic acid. They are just a little different chemically. But both are naturally occuring. I do not know why isotretinoin is used in accutane and not tretinoin though. Retin a does help a little with managing oil production as it shrinks pores, improves keratinization, unclogs pores (which means you actually may get more oil after you use it like me). Isotretinoin is found in accutane, and tretinoin is found in retin a, not the other way around.
