Getting lip injections for the first time can feel exciting — and a little nerve-wracking. You may be wondering what to avoid before your appointment, how much swelling to expect, whether lip filler hurts, and how to make sure your results look natural.
A little preparation can make your appointment feel smoother, safer, and more comfortable.
At Snap Glam Med Spa in Los Angeles, we guide every patient through the full lip injections process, from consultation to aftercare, so you feel informed before treatment begins.
How Should You Prepare for Lip Injections?
To prepare for lip injections, avoid alcohol before treatment, ask your provider about medications or supplements that may increase bruising, eat before your appointment, stay hydrated, avoid booking right before a major event, and tell your provider about allergies, cold sores, pregnancy, breastfeeding, medical conditions, and previous filler. Always follow your injector’s exact instructions.
Why Preparation Matters Before Lip Fillers
Lip injections are non-surgical, but they are still an injectable cosmetic treatment. Your lips are sensitive and have many small blood vessels, so swelling, bruising, tenderness, and redness can happen after treatment.
The American Academy of Dermatology notes that redness, swelling, tenderness, and occasional bruising can occur after filler injections and often clear within 7 to 14 days, if not earlier.
Good preparation can help you:
- Lower your chance of unnecessary bruising
- Feel more comfortable during your appointment
- Understand what results are realistic
- Plan around swelling and recovery
- Reduce stress before treatment
- Know what to tell your provider
- Avoid last-minute surprises

1 Week Before Lip Injections: Start Planning Ahead
About a week before your appointment, start thinking about your schedule, medications, skincare, and expectations.
Avoid Booking Right Before a Big Event
Do not schedule lip injections the day before a wedding, photoshoot, vacation, date night, or major event. Even beautifully done filler can cause temporary swelling or bruising.
A safer plan is to schedule your appointment at least two weeks before an important event when possible. This gives your lips time to settle and gives you room for a follow-up if needed.
For a recovery breakdown, read: Lip Filler Swelling Stages.
Review Your Medications and Supplements
Some medications and supplements may increase bruising risk. This can include certain pain relievers, blood thinners, fish oil, vitamin E, and other supplements.
Important: Do not stop prescribed medication without approval from your doctor. If you take blood thinners or have a medical condition, tell your provider before treatment.
Avoid Dental Work Close to Filler
Dental work can place pressure on the lips and may increase irritation around the mouth. Cleveland Clinic’s lip filler aftercare guidance notes that patients should avoid dental work for two weeks before or after filler injections to reduce infection risk.
If you have upcoming dental treatment, mention it when scheduling your filler appointment.
48 Hours Before Lip Injections
The two days before your appointment are a good time to avoid anything that may increase swelling, bruising, or irritation.
Avoid Alcohol
Alcohol can increase bruising risk. Cleveland Clinic notes that patients should avoid alcohol for at least 24 hours after lip filler because alcohol thins the blood and can make bruising worse. Many providers also recommend avoiding alcohol before treatment.
Skip Harsh Lip Treatments
Avoid irritating lip scrubs, aggressive exfoliation, waxing around the mouth, or strong active products near the lips right before treatment.
Your skin should be calm before injections.
Stay Hydrated
Drink water and keep your body hydrated. Hydration supports your overall skin health and helps you feel better before and after your appointment.
24 Hours Before Lip Injections
The day before your appointment, keep things simple.
Eat Well and Hydrate
Do not show up hungry or dehydrated. Eat a normal meal before your visit, especially if you feel nervous around needles.
Avoid Heavy Alcohol and Late Nights
Try to get good sleep and avoid alcohol. Being tired, dehydrated, or hungover can make your appointment feel more uncomfortable.
Confirm Your Appointment Details
Make sure you know:
- Appointment time
- Location
- Payment or financing options
- Whether you need to arrive early
- Whether makeup should be avoided
- Any instructions from your provider
Snap Glam also offers flexible financing options, including Cherry Payment Plans, CareCredit, and in-house layaway plans, so you can plan your treatment with more confidence.
What to Tell Your Provider Before Lip Injections
Your consultation is not just about choosing lip size. It is also about safety.
Tell your provider if you:
- Have allergies
- Are pregnant or breastfeeding
- Have a history of cold sores
- Take blood thinners
- Take regular medications or supplements
- Have autoimmune conditions
- Have had previous lip filler
- Have had filler dissolved before
- Recently had dental work
- Have an active infection or skin irritation
- Have had reactions to injectables
- Have a major event coming up soon
The FDA advises patients to work with a licensed healthcare provider who has experience with dermal fillers, understands anatomy, and can discuss risks, benefits, and complications before treatment.
What If You Get Cold Sores?
If you have a history of cold sores, tell your provider before treatment. Lip injections may trigger a cold sore outbreak in some patients.
Your provider may recommend rescheduling if you have an active cold sore or may discuss preventive medication when appropriate.
Do not hide cold sore history. It helps your provider plan safely.
Should You Bring Reference Photos?
Yes, reference photos can help communicate your goals — but they should be realistic.
Bring photos that show:
- The general shape you like
- The level of fullness you prefer
- Whether you want subtle or noticeable results
- What you do not want
However, your result should be based on your face, not someone else’s lips. The best filler results fit your natural anatomy.
For more on this, read: How to Avoid Overfilled Lips.
Should You Choose 0.5ml or 1ml Before the Appointment?
You can think about your preference, but you do not need to decide alone before your visit.
In general:
- 0.5ml may be better for subtle volume, hydration, and first-time patients who want a soft change.
- 1ml may be better for more visible fullness, shape, and definition.
Your provider should help you choose based on your lip size, lip shape, symmetry, facial balance, and goals.

What to Avoid Before Lip Injections
Before your appointment, your provider may recommend avoiding:
- Alcohol
- Harsh lip exfoliation
- Lip waxing close to treatment
- Dental work close to filler
- Heavy makeup on the treatment area
- New lip products that may irritate your skin
- Blood-thinning supplements unless medically approved
- Stopping prescribed medications without doctor approval
- Booking treatment right before a major event
The goal is to keep your lips and surrounding skin calm before treatment.
What to Do the Morning of Your Appointment
On the day of your appointment:
- Eat a light meal
- Drink water
- Brush your teeth gently
- Arrive with clean lips
- Avoid heavy lipstick or lip liner
- Bring questions for your provider
- Be honest about your nerves
- Share your exact goals
- Tell your provider about any new symptoms
If you feel sick, have an active cold sore, or have an infection near the lips, call the med spa before coming in.
What Happens During a Lip Injection Appointment?
Your appointment usually includes a consultation, lip assessment, numbing, injection, and aftercare review.
Consultation
Your provider reviews your goals, medical history, previous filler, and any concerns.
Lip Assessment
Your lips are checked for shape, symmetry, volume, movement, and facial balance.
Numbing
Topical numbing cream may be applied to reduce discomfort. Some fillers also contain lidocaine.
Injection
Small amounts of filler are placed into targeted areas of the lips.
Aftercare Review
Before you leave, your provider explains what to expect, what to avoid, and when to call.
If pain is your biggest concern, read: Do Lip Injections Hurt.
Do Lip Injections Hurt More If You Are Nervous?
Feeling nervous can make normal sensations feel stronger. The lips are sensitive, so some pinching or pressure is expected, but numbing helps.
If you are anxious, tell your provider. A patient-focused injector will talk you through the process and give you time to feel ready.
How Much Downtime Should You Plan?
Lip injections usually do not require major downtime, but you should plan for visible swelling and possible bruising.
The FDA notes that swelling and bruising are common dermal filler side effects that often happen shortly after injection and many resolve within days to weeks.
Plan for:
- Swelling in the first 24 to 48 hours
- Possible bruising
- Tenderness
- Temporary firmness
- A more settled look around one to two weeks
For aftercare steps, read: Lip Injections Aftercare.
What Should You Avoid Right After Lip Injections?
After treatment, your provider may recommend avoiding:
- Alcohol for at least 24 hours
- Heavy exercise for 24 to 48 hours
- Excessive heat
- Saunas or steam rooms
- Pressing or massaging the lips unless instructed
- Kissing right away
- Lip makeup until cleared
- Dental work close to treatment
- Sleeping face down
The American Society of Plastic Surgeons recommends avoiding intense physical activity for the first 24 to 48 hours after dermal fillers to reduce swelling and bruising.
When Should You Call Your Provider After Treatment?
Call your provider if you notice:
- Severe or worsening pain
- Skin that turns white, gray, purple, or blotchy
- Skin that looks dusky
- Severe one-sided swelling
- Increasing warmth or redness
- Fever
- Pus or signs of infection
- Trouble breathing
- Vision changes
- Painful lumps that grow
- Symptoms that suddenly worsen after improving
A 2024 medical review notes that dermal filler side effects can range from mild to serious, including swelling, pain, tenderness, bruising, infection, nodules, migration, and vascular compromise.
