Dermal filler is an injectable gel — most commonly made from hyaluronic acid (HA) — that adds volume, softens lines, and restores structure to the face. At The Injection Bar in St. Louis, we use Restylane and RHA Collection fillers to treat areas like the lips, cheeks, under-eyes, jawline, chin, nasolabial folds, and marionette lines. HA fillers are dissolvable, making them one of the safest and most versatile options available.

Restylane is a trusted, long-established HA filler available in multiple formulations — ideal for precise sculpting of lips, cheeks, and under-eyes. RHA Collection is a newer, more flexible filler designed to move naturally with your facial expressions, making it an excellent choice for dynamic areas like the lips and nasolabial folds. Your injector will recommend the right product based on your anatomy and goals.

At The Injection Bar STL, filler is priced per syringe. Pricing varies slightly by product — your injector will give you a clear cost estimate during your consultation before any treatment begins. We believe in transparent pricing with no hidden fees or upsells. We also periodically offer filler promotions — follow us on Instagram or join our loyalty program to stay in the loop.

Most HA fillers last 9–18 months depending on the product used, the area treated, and your individual metabolism. Lips tend to metabolize filler faster (closer to 6–9 months), while cheek and jawline filler can last a year or more. Consistent maintenance appointments help sustain results over time.

Yes — hyaluronic acid fillers like Restylane and RHA can be dissolved with an enzyme called hyaluronidase if you're ever unhappy with your results or experience a complication. This is one of the key safety advantages of HA-based fillers over permanent or semi-permanent options. Your safety and satisfaction are always the priority at The Injection Bar.

Your appointment starts with a consultation to discuss your goals and assess your facial anatomy. A topical numbing cream is applied, and most fillers also contain lidocaine to minimize discomfort during injection. The treatment itself takes 30–60 minutes depending on the areas treated. You may experience some swelling, bruising, or tenderness for a few days post-treatment — this is completely normal. Most clients are back to their routine the same day.

Lip filler uses hyaluronic acid gel injected into and around the lips to add volume, define the lip border, correct asymmetry, and enhance your natural shape. At The Injection Bar in St. Louis, we use Restylane and RHA Collection products specifically formulated for the lips — designed to feel soft and natural, not stiff or overdone.

Item deLip filler at The Injection Bar STL is priced per syringe. Most first-time lip filler clients start with 0.5–1 syringe, which is enough to see a meaningful, natural-looking result. Your injector will walk you through what to expect for your specific lip shape and goals. We keep our pricing transparent — what you're quoted is what you pay.scription

Item descriptiNatural results are our standard. Our injectors specialize in lip enhancement that complements your features — not the "overfilled" look. We take a conservative approach with new clients, building volume gradually so you always feel confident in your results. If you want more after your initial appointment, we can always add — but we'd rather go slow than overshoot.on

Lip filler typically lasts 6–9 months, though this varies by individual. The lips are a high-movement area, which means filler metabolizes faster here than in areas like the cheeks or jawline. Most clients return every 6–8 months to maintain their results.

Most clients describe the sensation as mild discomfort rather than pain. We apply a topical numbing cream before treatment, and the filler itself contains lidocaine for additional comfort during injection. Lips are one of the more sensitive areas, but the process is quick — most lip filler appointments are done in under 30 minutes.
