Once you and your provider have decided that dermal filler is appropriate, knowing what happens next can make the appointment feel much more comfortable.
Preparation, treatment, and recovery vary depending on the product and area being treated. Here is what to expect at Modern Aesthetics, along with the information I want you to share before your appointment.
Before your appointment
Tell me about your medications, supplements, allergies, medical conditions, previous filler, and any past reactions to injectable treatments. If you know which products were previously used and where they were placed, that information is helpful.
Mention any history of cold sores, particularly before lip treatment. Let me know about recent illness, vaccinations, dental work, other procedures, and upcoming travel or important events so we can discuss appropriate timing.
Some medications and supplements can increase bleeding or bruising. Do not stop prescribed aspirin, anticoagulants, or other medications without guidance from your prescribing clinician. We will review whether any changes to your treatment plan or timing are appropriate.
Contact the practice before coming in if you develop a cold sore, rash, infection, or significant irritation near the planned treatment area.
On the day of treatment
Arrive with clean, makeup-free skin whenever possible. Eat beforehand and stay hydrated.
We will review your goals, confirm the treatment plan, and discuss the selected product, anticipated improvement, limitations, and risks. Photos document your starting point and help us assess changes over time.
Comfort measures are selected based on the treatment area and your needs. The skin is cleansed and prepared before injection.
During the procedure
Filler may be placed using a needle, a cannula, or a combination of the two. The choice depends on the area, product, anatomy, and treatment plan. Neither method eliminates the risk of complications.
You may feel pressure, pinching, or tenderness. Let me know immediately if you experience unusual pain or any visual symptoms.
Appointment length varies with the number of areas being treated and the complexity of the plan. There is time to pause, ask questions, and assess your comfort throughout treatment.
What to expect afterward
With hyaluronic acid filler, added volume is visible immediately, but swelling can temporarily change the appearance of the result. Bruising, tenderness, redness, and firmness may also occur.
Swelling can be uneven, particularly early in recovery. Lips may swell more noticeably than other areas. Follow the aftercare instructions provided for your treatment, including guidance about makeup, exercise, heat exposure, and touching the area.
Avoid pressing, massaging, or attempting to reshape your filler unless specifically instructed.
When should you assess your results?
A review around two weeks is often useful, but complete settling may take longer depending on the product, area, and your individual response.
An early follow-up does not automatically mean more filler is needed. Sometimes the appropriate next step is allowing additional time for swelling to resolve.
When to seek help
Contact me immediately for unusual or worsening pain, white or blanched skin, dusky discoloration, or a spreading mottled appearance. Increasing warmth, spreading redness, drainage, or fever also warrants prompt assessment.
Vision changes or stroke symptoms require emergency medical attention. Call 911 and notify your injector.
Do not wait for a routine follow-up if something feels wrong.
