Chemical peel and filler. How long should I wait between treatments?

To answer a question like this, your physician needs to think about things from both an anatomic and physiologic standpoint. Your filler is generally deep, somewhere between your dermis, subcutaneous fat, and bone. Botox is targeting the muscles of facial expression, which are also deep. Your chemical peel is targeting the top of your skin, even with a medium depth peel, it may cause some edema or light swelling of the area, but it should not affect the other two treatments and you should be fine to get them all the same day. I'm always surprised when I see the literature about combining treatments and really how much you can combine with simultaneous treatments and have the same or even sometimes better results. Make sure you are under the care of someone with an intimate knowledge of the skin, not just these cosmetic treatments. That level of comfort will go a long way in these sorts of situations. A Dermatologic surgeon would who is fellowship trained would be a great place to start. 

You can certainly get your Botox and Fillers the same day without a problem. If you had your chemical peel prior to all these injections or a few days after, i dont see any issue with it at all. Be sure to ask the physician treating you their opinion.Dr JP Bonaparte

In our office we recommend 2 weeks in between treatments and usually have our patients do their chemical peel first.  I hope this was helpful, good luck to you!
