Is it okay to book my botox and filler while on my period?
If you’ve ever had an injection appointment feel surprisingly uncomfortable when the last one was completely manageable, it’s reasonable to wonder what changed. The treatment? Your sleep? The fact that your period is due tomorrow and even your bra feels offensive?
Your menstrual cycle may be part of that picture. But before you start rearranging every appointment around your period, I want to separate what we understand about hormones and pain from what we can actually promise about cosmetic injections.
If you’re new here, hi! I’m Dr. Heather Iverson, Naturopathic Doctor with a focus on perimenopause and cosmetic injector with a focus on natural results, I offer Sculptra, botox and dermal filler in the Comox Valley, Nanaimo and Parksville, with treatment plans that account for your goals and comfort.
How can your cycle impact your pain
Estrogen and progesterone fluctuate throughout a natural menstrual cycle. Estrogen generally rises before ovulation, while progesterone rises afterward. Both fall before your period if pregnancy hasn’t occurred. These hormones also influence the nervous system, including pathways involved in processing and regulating pain. Estrogen, for example, interacts with the brain’s own natural pain-relieving system.
That doesn’t translate neatly into “more estrogen means less pain.” Hormones interact with each other, their effects vary between people, and different kinds of pain behave differently. Research on a painful stimulus in a laboratory cannot automatically tell us how your next lip filler appointment will feel.
The days before your period and the first few days of bleeding are worth paying attention to if that is when you feel more sensitive. Premenstrual symptoms, cramps, headaches and disrupted sleep can make an already uncomfortable day feel like a poor time for needles. During menstruation, prostaglandins help the uterus contract and contribute to cramping. That explains period pain; it doesn’t prove those same chemicals make cosmetic injections hurt more.
I also don’t want anyone hearing that pain is “just hormones.” Your experience deserves to be taken seriously, whether we can neatly explain it or not.
The research specifically looking at aesthetic treatments is still limited. A 2025 questionnaire study involving 383 participants found that more severe premenstrual symptoms were associated with greater reported pain during cosmetic injections. However, pain scores for injectables did not differ significantly between the menstrual timing windows studied.
The study also grouped together botox, filler, mesotherapy and PRP, which are all very different experiences. Plus, we can’t establish that hormones caused someone’s discomfort. That said, there is a reason they say waxing hurts more leading up to your period and I urge you to trust the personal patterns you begin to see.

The best time of your cycle to book injections
If you feel more tender or sensitive before or during your period, try booking after your period finishes, once those symptoms have settled. If you don’t notice a change in your sensitivity throughout the month, there’s no need to plan your injections around your cycle. Research hasn’t identified one best day for everyone, so I wouldn’t have you counting down to “day seven” or cancelling simply because your period arrived.
Hormonal birth control and perimenopause can make the usual cycle pattern less predictable, too. Pay attention to how you actually feel. If you’re unsure, let’s talk about your treatment cadence during your next visit.

How your period may impact your recovery
We do not have good clinical evidence that a particular menstrual phase makes injection sites heal faster, prevents bruising or helps filler settle better. Feeling more comfortable during recovery and recovering biologically faster are different things.
If you already feel puffy or tender around your period, you may prefer to avoid overlapping that experience with temporary swelling after filler. That is a reasonable comfort consideration, without promising that another week will produce less swelling.
The appointment itself matters too: the area treated, product, technique and your individual tendency to bruise. For an important event, I recommend leaving at least three weeks after treatment, with more time if your treatment plan or previous recovery calls for it. Your calendar needs room for recovery regardless of where you are in your cycle.
What about bruising?
Hormones can influence how our blood clots, but we don’t have strong evidence that being on your period automatically means more bruising after injections. If you’ve noticed that pattern yourself, tell me—we can take it into account when creating your treatment plan. I also want to know what you’ve taken for cramps. Medications such as ibuprofen and aspirin can increase bruising risk, which may explain part of the connection for some people. Please don’t stop prescribed medication without consulting your family doctor.

As for how often you need treatment, there is no good evidence that booking at a particular cycle phase makes botox or filler last longer. My usual neuromodulator spacing is around three to four months, adjusted to the person. Filler maintenance depends on the product, area and what remains from previous treatment. We can discuss adjusting your treatment cadence slightly to fit into a more comfortable week for you.
Please feel comfortable telling me when something hurts and asking your “silly” questions. And if you’re keen on getting to know your cycle on a deeper level, I also offer support there.
