I was wondering whether the use of Tazorac specifically can in any way undo the effects of dermal fillers such as Restylane or Perlane? I haven't seen anything around this in the mainstream press or the Internet but am wondering if there are any studies or even anecdotal evidence one way or the other? Given both seem to stimulate collagen production do they work in synergy if applied to the same area? Is it the case that they both stimulate collagen through "controlled injury" to the skin.
Does Tazorac Impact Long-term Effects of HA Dermal Fillers Like Restylane and Perlane?

Topical treatments and Perlane
The use of Tazorac topically won't have any affect on dermal filler treatments. Topical retinoids are used to help diminish fine lines - and treat your skin, not facial volume. Having this discussion with your provider should help you understand further how each product is devised to work.
Tazorac and fillers
Tazorac won't have any positive or negative affect on fillers. It's a much more superficial product than any filler and so it affects on the top layers of the skin, working to improve very fine lines and skin tone and texture. Fillers are placed much deeper and so those affect underlying collagen and deeper lines. The two wouldn't affect each other, positively or negatively.
There isn't any way topical Tazorac would have a detrimental effect on any injectable filler. You can use Tazorac indefinitely to improve and prevent photoaging of the skin along with daily use of a sunscreen which adequately blocks UVA.
