Facial Fillers: What You Need to Know
If you’re considering facial fillers, you’ve probably heard of Restylane and Juvederm. These two popular injectable treatments are widely used to restore facial volume, soften wrinkles, and enhance features like lips and cheeks. To help you make an informed decision, we asked Dr. M. Tahsini—board-certified and a Fellow of the American Academy of Anti-Aging Medicine—for his insights.
What Are Fillers Used For?
Dermal fillers are non-surgical injectables used to:
- ✅ Smooth fine lines and deeper wrinkles
- ✅ Add volume to lips, cheeks, and under-eye hollows
- ✅ Fill facial folds like nasolabial and marionette lines
- ✅ Enhance jawline or restore symmetry
- ✅ Improve contour in areas like hands or even buttocks
Restylane and Juvederm are hyaluronic acid-based fillers, meaning they use a naturally occurring sugar molecule that hydrates and plumps the skin. Both are FDA-approved and widely trusted in the aesthetics community.
Where Can Fillers Be Injected?
Common treatment areas include:
- 🔹 Nasolabial folds (lines from the nose to the mouth)
- 🔹 Marionette lines (from the mouth to the chin)
- 🔹 Lips (for volume and shape)
- 🔹 Cheeks and cheekbones
- 🔹 Fine lines above the upper lip
What’s the Right Age to Start Fillers?
Most people start in their 30s, but some begin in their mid-20s if fine lines or early signs of aging appear. Ideal candidates may also include those with sun-damaged or dehydrated skin, or anyone experiencing volume loss from aging.
How Long Do Fillers Last?
Longevity depends on the product, the treatment area, and your metabolism. On average:
- Restylane lasts 6–12 months (up to 18 months with Restylane Lyft)
- Juvederm lasts 6–12 months (Voluma XC may last up to 24 months in the cheeks)
Because fillers stimulate your own hyaluronic acid production, patients who return regularly often require less product over time.
When Will I See Results?
Results are visible immediately after injection but take 7–10 days to fully settle. Some mild swelling or bruising may occur during that period.
Are There Side Effects?
Most patients experience minor swelling, bruising, or redness for a few days. These effects are temporary. There’s no downtime, and most people resume normal activities right after treatment.
What Happens When Fillers Wear Off?
Once fillers metabolize, your skin gradually returns to its baseline condition. However, many patients find the refreshed appearance so satisfying that they continue with maintenance treatments to preserve results. Learn more about ongoing filler care.
How Much Do Fillers Cost?
Pricing is typically based on the number of syringes used. One or two syringes are often needed for areas like smile lines. While prices vary slightly by clinic, the skill and certification of your injector matter more than the price. Always choose a licensed provider in a medical setting.

Which Filler Is Right for Me?
The best filler depends on your goals, facial structure, and how long you want results to last. A professional consultation is essential. Your provider can evaluate your skin and recommend the right product and injection plan. For lip enhancements, check out our Complete Guide to Lip Fillers.
