Lip Fillers 101: What to Expect Before, During, and After Treatment

Looking for natural-looking lip enhancement? Juvedérm® lip fillers offer a smooth, balanced, and customizable solution for fuller lips. Learn how to achieve soft, natural results with expert guidance.


Ever look in the mirror and imagine how your face would light up with just a bit more volume in your lips. You’re not alone. Fuller, more defined lips have become one of the most popular beauty enhancements today—and for good reason. Whether you’re going for a soft, natural enhancement or something more dramatic, lip fillers are a quick, safe, and customizable solution. 

If you’re new to the treatment or just want a deeper understanding of what’s involved, this guide will walk you through everything—before, during, and after your appointment—so you can feel confident at every stage.

What Are Lip Fillers, Really?

Let’s start with the essentials. Lip fillers are injectable gels made from hyaluronic acid, a substance naturally found in the body that holds moisture and adds volume. These cosmetic injections can do more than just plump your lips—they help smooth out fine lines, define shape, and create better facial harmony.

The hyaluronic acid in the filler works by drawing water into the lips, giving them a soft, supple, and hydrated appearance. When performed by a skilled professional, lip injections enhance your natural beauty, offering results that are tailored to your facial structure and personal aesthetic.

What to Know Before Your Appointment

Good results begin with smart preparation. Here’s what you should do in the days leading up to your treatment:

  • Avoid blood-thinning substances like aspirin, ibuprofen, fish oil, and alcohol for at least 24–48 hours. This reduces your risk of bruising.
  • Stay well-hydrated and maintain a healthy skincare routine—hydrated skin responds better to dermal fillers.
  • Be transparent with your injector about any medications, allergies, or past reactions to fillers.
  • If you’re prone to cold sores, ask about preventive antiviral medication.
  • Arrive with a clean face—no makeup on or around your lips.

By prepping properly, you’re giving yourself the best chance for a smooth treatment and beautiful results..

What Happens During the Procedure?

Now, let’s talk about the moment you’ve been waiting for—your actual lip injection session.

Here’s how the process typically unfolds:

  • A numbing cream is applied to ensure your comfort.
  • Once numb, your injector will use a very fine needle to place the lip fillers strategically.
  • You may feel light pressure or a small pinch during the process, but most people find it very tolerable.
  • The treatment usually takes around 20 to 30 minutes, depending on how much volume is being added.
  • Immediately after, your lips may look fuller than expected due to swelling, but this settles within a few days.

Because cosmetic injections are customized, you can choose to keep things subtle or go for a more dramatic look—whatever fits your style.

Aftercare: Keeping Your Lips Healthy Post-Treatment

Post-treatment care is essential to make sure you heal beautifully and get the best results from your lip fillers. Here’s what to keep in mind:

  • Expect mild swelling, tenderness, or bruising for a couple of days—this is completely normal.
  • Avoid touching or pressing your lips for the first 24 hours.
  • Ice packs (wrapped in a cloth) can help with swelling.
  • Sleep with your head elevated for the first night.
  • Avoid alcohol, spicy foods, and strenuous exercise for at least 24 hours.
  • Keep your lips moisturized and stay hydrated.

Following this filler aftercare routine helps your lips settle in nicely and minimizes the risk of complications.

How Long Do Results Last?


One of the best things about lip injections is that the results are long-lasting, yet not permanent—giving you the flexibility to evolve your look over time. Most people enjoy their enhanced lips for about six to twelve months. Factors like metabolism, lifestyle, and the type of filler used can influence how long the effects last.

To maintain your desired appearance, you can return for touch-ups every six to nine months. Whether you want to gradually build volume or keep things consistent, lip fillers allow you to refresh your look at your own pace.

Final Thought

Choosing to get lip fillers is about more than just appearance—it’s a personal decision that reflects how you want to feel and present yourself to the world. When done right, they offer an elegant enhancement that highlights your natural beauty, not hides it. Whether you’re taking the first step or continuing your beauty journey, understanding the process gives you the confidence to move forward.
