Preparing for lip filler starts about two weeks before your appointment and involves a short list of straightforward steps: stopping certain medications and supplements, adjusting your skincare routine, and timing the appointment well. Most of the prep is about reducing bruising and swelling so your results look great as quickly as possible.
Two Weeks Before: Supplements to Stop
Several common supplements increase bleeding under the skin, which translates directly to more bruising after lip injections. High-dose vitamin E, ginkgo biloba, garlic supplements, fish oil, and omega-3 capsules all interfere with how your blood clots. Stop taking these two weeks before your appointment. If you take a daily multivitamin with a standard amount of vitamin E, that’s generally fine, but standalone high-dose vitamin E should be paused.
Turmeric and ginseng supplements also thin the blood and belong on the same stop list. If you’re unsure about a specific supplement, the simplest approach is to pause anything that isn’t medically necessary for those two weeks.
One Week Before: Medications and Bruise Prevention
Aspirin, ibuprofen (Advil, Motrin), and naproxen (Aleve) all increase bruising risk. Avoid these for at least a week before your appointment. Acetaminophen (Tylenol) is a safe alternative for pain relief during this window since it doesn’t affect clotting.
If you take a prescription blood thinner like warfarin or clopidogrel, do not stop it on your own. Talk to your prescribing doctor about whether a temporary pause is safe for you.
This is also a good time to start bromelain, a pineapple-derived supplement available at most drugstores and health food stores. Taking 500 mg twice daily for the week leading up to your appointment can noticeably reduce bruising and swelling. You can continue it for two weeks afterward as well.
If You Get Cold Sores
Lip filler injections can reactivate cold sores (herpes simplex) in people who carry the virus, even if you haven’t had an outbreak in years. The needle trauma and swelling around the lip tissue are enough to trigger one. If you have any history of cold sores, let your injector know ahead of time. They’ll typically prescribe an antiviral to start two days before your appointment and continue for about a week. This simple step almost entirely eliminates the risk of an outbreak disrupting your results.
Two Days Before: Skincare Adjustments
Stop using any active skincare products around your mouth at least two days before your appointment. This includes retinol, tretinoin (Retin-A), retinoids, glycolic acid, and other exfoliating or anti-aging products. These ingredients thin and sensitize the skin, making the injection site more prone to irritation and slower to heal. A basic gentle cleanser and moisturizer are all you need on the lower half of your face in the days leading up to treatment.
24 Hours Before: Skip the Alcohol
Alcohol thins the blood and increases bruising risk, so avoid it for at least 24 hours before your appointment. Stanford Medicine’s pre-treatment guidelines specifically recommend this window. If your appointment is on a Saturday morning, Friday evening drinks are worth skipping. Some injectors suggest a 48-hour window for heavier drinkers, but 24 hours is the standard minimum.
Day of Your Appointment
Eat a normal meal before you go. Showing up on an empty stomach increases your chance of feeling lightheaded or dizzy during the injections, which involve a series of small needle pokes in a sensitive area. A regular breakfast or lunch gives your blood sugar a stable baseline.
Stay well hydrated. Hyaluronic acid fillers, the type used in nearly all lip injections, work by attracting and holding water. Showing up hydrated helps the filler integrate smoothly into the tissue. Drink water normally throughout the day rather than trying to overcompensate right before.
Come with a clean face, or at least clean lips. Skip lipstick, lip liner, and heavy foundation around your mouth. Your injector will clean the area, but starting with bare skin makes the process easier and more hygienic. If you wear makeup to the appointment, bring a small bag so you can reapply everything except the lip area afterward.
Timing Around Events
Lip filler results aren’t instant. Your lips will be noticeably swollen for the first few days, and most people look photo-ready within 7 to 10 days. Final results, where the filler has fully settled into its shape and all swelling has resolved, take up to two weeks.
If you’re prepping for a specific occasion, here’s how far in advance to book:
- Weddings: 4 to 6 weeks before
- Vacations (especially beach or sun-heavy trips): 3 to 4 weeks before
- Photoshoots or headshots: 2 to 3 weeks before
- Parties or holidays: 2 to 4 weeks before
The extra buffer beyond the two-week settling period gives you time for a touch-up if needed and ensures any residual firmness in the filler has softened completely.
Things That Could Postpone Your Appointment
Active infections near the mouth are a firm contraindication for lip filler. If you have a cold sore outbreak, a dental infection, or any oral mucosal infection at the time of your appointment, you’ll need to reschedule. Injecting filler into tissue near an active infection risks spreading the infection deeper or causing a serious complication.
Recent dental work is worth mentioning to your injector. If you’ve had a tooth extraction, root canal, or deep cleaning within the past couple of weeks, the area may still be healing, and bacteria from dental procedures can linger. Most injectors prefer to wait until your mouth has fully healed.
