Lip filler programs remain extremely popular with no signs of slowing down, as they help enhance lip shape for a fuller, more attractive look. They effectively correct thin lips, downturned mouth corners, or concerns about natural lip shape—without the need for surgery. In 2025, there are also many trending lip styles to choose from, making lip filler treatments more versatile than ever.
Many people wonder, “Is 1 CC enough for a lip filler program?” And besides Juvederm and Restylane, the Korean brand Neuramis has also become a popular choice for its good results at a friendlier price.
MEGA CLINIC will take you through an in-depth look at the benefits of lip filler treatments—from choosing the right brand to suit your needs, answering all common concerns, and explaining important aftercare guidelines. What should you avoid after lip fillers? How many days does it take to settle? Can you sleep on your side? We’ll also update you with this year’s most stunning lip filler shape reviews—all in one place.
Filler program is made of hyaluronic acid (HA), a substance naturally found in our skin and joints. Its job is to retain water, keeping skin hydrated, firm, and elastic.
When used as a lip filler program, HA is injected into the lips to add volume, shape, and definition. The substance naturally dissolves over time and is FDA-approved for safety.
With the right technique, doctors can sculpt the HA to enhance the lips so they look balanced and suit the overall face.
Everyone’s lips look different due to genetics, ethnicity, and changing beauty standards.
Some people want fuller lips for aesthetic reasons, while others simply want to fix existing issues such as:
Lip filler programs are suitable for:
The result of 1 CC lip filler program depends on your natural lips. If you already have some volume, 1 CC is often enough. But for very thin lips or if you want a bold “Western-style” plump look, more than 1 CC may be needed. The doctor will assess the right amount for each person.
Cases where 1 CC is usually enough: For people with dry lips that have fine lines, lips with wrinkles or grooves, or those who already have enough lip tissue but simply want a little extra volume.
Lip filler programs make lips look better immediately after injection, but the HA will gradually settle and soften within about 1 month. Results usually last 8–12 months before naturally dissolving.
Since lips are thin and constantly moving, filler injection program in this area breaks down faster than other parts of the face. If the shape starts to fade, you don’t need to wait for all the HA to dissolve because top-ups can be done anytime. Many clients start with 1 CC and later add more for the perfect shape.
Lip filler programs can enhance shape and fullness in many styles—Korean-style lips, Douyin lips, Western plump lips, or Cupid’s bow. It’s perfect for those who want to reshape their lips without surgery. While results aren’t permanent, filler programs can be repeated to maintain the look. The key benefit: no scars, no downtime, and easy aftercare.
Lip surgery (lip reduction or reshaping) is more suitable for people with very thick lips or excessive tissue. Results are permanent, but if the outcome isn’t what you hoped for, it’s harder to correct since the tissue has already been removed.
Yes. Lip filler program can correct downturned mouth corners. Doctors inject it at the corners to push and lift the lip line upwards. The effect is visible right away, making the face look softer, friendlier, and naturally smiling.
At MEGA CLINIC, our doctors recommend these three brands for lip filler programs:
Yes. Neuramis has a very natural texture, holds shape well, and comes at a friendly price point. It works on multiple areas of the face, including the lips. It’s a great choice for those who want sharp, eye-catching lips that get noticed right away.
Not necessarily. You can switch between different brands or models as long as they are HA filler programs approved for safety. The doctor will evaluate which type is most suitable for your lips and desired results.
If you bruise easily, it’s recommended to stop certain medications and supplements at least 2 weeks before treatment, such as Aspirin, NSAIDs, Vitamin E, Vitamin K, fish oil, and Primrose, since these can slow blood clotting and increase bruising.
Also, avoid alcohol for at least 24 hours prior, as it dilates blood vessels and can make bruising more visible.
Aftercare helps HA settle smoothly, keep their shape, and last longer. Doctors recommend:
Other than that, you can live normally, like washing your face, applying skincare, masking, drinking hot coffee or tea, or enjoying hot food like noodles, shabu, or BBQ.
There may be mild swelling in some cases, which can make the lip shape less defined during the first 7–14 days. The swelling will gradually subside, and the filler will fully settle and blend naturally with the tissue within approximately 4 weeks.
Before getting a lip filler injection program, make sure the clinic meets safety standards. Here’s what to check:
Lip filler program is made of HA, which naturally dissolves in the body. They make lips fuller, softer, and more defined. During injection, you may feel slight discomfort or pressure, but many filler program brands like Neuramis Deep and Restylane Kysse already contain anesthetic. If you’re worried, numbing cream can also be applied before the treatment.
Fake filler programs are non-HA substances not approved by the FDA. The most common is liquid silicone, which is very dangerous as it can harden into lumps, deform the lips, cause chronic swelling, and cannot dissolve naturally. Correction usually requires surgery.
Yes. It’s common to feel small lumps or firmness in the first days because the HA hasn’t fully settled. Usually, it blends smoothly with the lips within about 4 weeks.
If HA filler program was used, it can be dissolved with an enzyme called Hyaluronidase. After it is dissolved, you can redo the treatment with a new shape. Always consult a doctor before dissolving or refilling.
Not at all. Filler program enhances your natural lips. For people with thicker lips, doctors use techniques like lifting corners or shaping a Cupid’s bow, so the lips look more defined and balanced, not oversized.
Lip filler injection program is allowed from 18 years old. If younger (but not under 15), a signed consent form from parents or guardians is required.
In some cases, yes. If lips are too thin after surgery, filler programs can sometimes restore volume. A doctor must first evaluate if it’s possible.
During the first 1–2 days after lip filler injections, brush your teeth as gently as possible using an extra-soft toothbrush. Avoid opening your mouth wide and try not to apply pressure near the lip borders. Choose a mild toothpaste and rinse with room-temperature water. It’s also recommended to avoid flossing during this period to reduce irritation. Once the swelling starts to subside usually around day 2 you may gradually return to your normal brushing routine, but continue to be careful to avoid any impact on the lips.
After the initial swelling period (around 4–5 days), you can resume normal oral care, including brushing your teeth and flossing. However, at any stage, avoid brushing too forcefully. It’s also recommended to avoid hot water and drink plenty of fluids to help the filler settle smoothly and reduce irritation.
After lip filler injections, it’s recommended to avoid sleeping on your side for the first 24–48 hours, as the filler has not fully settled and may shift or lose shape due to pressure. Sleeping on your back with two pillows to elevate your head is advised, as this helps reduce pressure and allows the lips to settle more beautifully.
The most effective early aftercare includes using a body pillow to prevent turning over while sleeping, avoiding touching or massaging the lips forcefully, and drinking plenty of water. Proper hydration helps the filler retain moisture and maintain its shape for longer-lasting results.
Yes. At MEGA CLINIC, many male clients get filler programs to correct thin, uneven lips or to add subtle volume for a more attractive look.
It’s best to avoid lipstick for the first 12 hours to prevent irritation. After that, you can apply as usual.
Yes, you can fly or travel immediately. However, if you want a follow-up appointment with the clinic, it’s best to schedule it within 1 month before a long trip.
