Hi Tatortot, USUALLY it is completely safe to have both procedures performed in close proximity (even during the same day/visit). However, the type of chemical peel and the concentration (strength) of that peel are important. For example, if you plan to be having a more superficial chemical peel (like a glycolic acid peel), you should be fine because the filler/Juvederm is placed deeper within the skin (deeper than the peel penetrates). However, I would recommend that you be more cautious if you are planning on having a stronger, deeper-penetrating chemical peel (like a 30% TCA peel) because these can penetrate to the dermis (deeper level of skin). You can also get quite a bit of swelling after both the deeper peel as well as the Juvederm injections to your lips, so I would recommend that you space them at least a week or two apart so that your doctor can best evaluate your face when he/she injects the filler (as opposed to having residual swelling from one procedure "muck up" the results from the other. Thus, assuming you plan to have a more superficial chemical peel, you should be fine to have the filler injected on the same day (just have the filler injected before the chemical peel and not v.v.). If you are planning a deeper chemical peel, it's best to wait a week or two between treatments. Always keep in mind that "this is a marathon and not a race". The BEST result is ultimately what you want. . . Waiting a week or two to error on the side of caution could prevent future issues that would make you regret your decision to have them both done at once. I hope this helps!Dr. Kiripolsky
