Introduction
The first two days after a cosmetic injectable treatment are when most of the questions come in: Is this swelling normal? Can I work out tomorrow? Why does this side feel tighter than the other? Here’s a clear breakdown of what to expect, what to do, and when it’s actually worth calling your provider. Most of what you’ll experience is mild and temporary, and knowing what’s typical ahead of time tends to make the healing process feel far less stressful.
Immediately After Treatment: What's Normal
Some redness, mild swelling, and small bumps at the injection sites are all typical in the first hour or two and usually resolve on their own. Bruising is also common, especially with filler, and can take anywhere from a few days to about two weeks to fully fade. Mild tenderness at the injection sites is expected as well. None of these on their own are cause for concern. They’re simply part of how the skin responds to any injection.
Some patients also notice a mild headache after Botox specifically, or a feeling of tightness or fullness after filler, particularly in the lips. Both tend to ease within a day or so as the treated area settles.
Activities to Avoid for 24 to 48 Hours
For the first day or two, it’s best to avoid strenuous exercise, saunas, hot yoga, and extended sun or heat exposure, all of which increase blood flow and can worsen swelling or bruising. If you’re a regular at Solidcore, Orangetheory, or a similar studio, plan to swap your usual class for a rest day or a light walk instead. It’s also worth avoiding alcohol during this window and, particularly after filler, avoiding pressure or massage on the treated area unless your provider has specifically instructed you to do so.
During DC’s more humid stretches, it’s also worth being mindful of extended time outdoors right after treatment. Heat and humidity can both contribute to more noticeable swelling than you might experience on a cooler, drier day.
Flying shortly after treatment is another common question. While air travel itself isn’t typically a problem, cabin pressure changes can sometimes make mild swelling feel slightly more noticeable, so if you have flexibility, giving yourself a day before a flight isn’t a bad idea.
Managing Bruising and Swelling
If bruising or swelling shows up, apply a cold compress gently (never press firmly) for short intervals during the first 24 hours. After that, some patients find gentle warmth helpful in speeding up the fading of a bruise. Arnica gel or supplements are a popular over-the-counter option many patients use, though results vary. You can typically apply makeup the following day to cover any visible bruising, once the injection sites have fully closed.
Sleeping slightly elevated on an extra pillow for the first night or two can also help minimize overnight swelling, particularly if you were treated in the under-eye or cheek area.
When to Call Your Provider
Most side effects are mild and temporary, but a few signs need prompt attention. Call your provider (or go to urgent care or the ER if after hours) right away if you notice any change in vision, sudden or severe pain, or skin that looks pale, mottled, or dusky, especially after treatment near the eyes or between the brows. These can be signs of a rare but serious complication and shouldn’t wait until your next visit.
Other signs are less urgent but still worth a call: significant asymmetry that hasn’t started to improve after a few days, unusual or worsening pain, or signs of infection such as increasing redness, warmth, or pus at an injection site. It’s always better to check in than to wait it out if something doesn’t feel right. Your provider would rather hear from you.
Long-Term Care to Extend Your Results
Beyond the first 48 hours, the habits that support your results are largely the same ones that support healthy skin overall: daily sunscreen, staying hydrated, and avoiding excessive sun exposure, which can accelerate the breakdown of both filler and your skin’s natural collagen. Keeping track of when you were treated, and booking your next appointment before results fully fade, also helps maintain a more consistent look over time rather than dramatic swings between “fully done” and “fully faded.”
If you notice your results seem to be changing unevenly over time, that’s worth mentioning at your next visit as well, since it can help your provider fine-tune your treatment plan going forward.
A simple habit that helps many patients: take a quick photo of the treated area about two weeks after each appointment, once results have fully settled. Over time, this gives you and your provider an easy visual reference for how your results are holding and when it’s genuinely time for your next visit, rather than relying on memory alone.
