If you’ve been curious about injectables but aren’t sure whether you need Botox®, fillers, or both, you’re asking exactly the right question. Botox® vs. fillers is one of the most common conversations we have in our clinic—and the answer matters, because these two treatments do very different things.

Here’s a clear breakdown of both, from the team at Darabi Dermatology, where we offer neuromodulators and fillers to help you look refreshed, natural, and like yourself!

What Is Botox® and What Does It Treat?

Botox® is a neuromodulator—it works by temporarily relaxing the facial muscles responsible for expression lines. (Botox® is a brand name; Dysport, Xeomin, and Jeuveau are FDA-approved alternatives that work the same way.) It’s best for dynamic wrinkles: the lines that appear when you move your face, like forehead creases, crow’s feet, and frown lines between the brows. Results appear within 1–2 weeks and typically last 3–4 months. Botox® does not add volume and is not the right tool for wrinkles visible at rest.

What Are Dermal Fillers and What Do They Treat?

Dermal fillers are injectable gels that restore lost volume, smooth static wrinkles, and contour the face. Unlike Botox®, results are often immediate. Common uses include dermal fillers on the face for nasolabial folds and marionette lines, dermal fillers for the cheeks to restore lost volume, lip enhancement, under-eye hollows, and a non-surgical lifting effect along the jawline.

Types of Dermal Fillers

There are several different types of face fillers, each suited to different goals:

  • Hyaluronic acid (HA): the most common type of injectable filler. Soft, reversible, and immediate. Brands include Juvéderm, RHA, Revanesse and Restylane. They last 6–18 months.
  • Calcium hydroxylapatite (CaHA): thicker, also stimulates collagen production. Best for deeper folds and volume loss. Lasts 12–18 months (Radiesse).
  • Poly-L-lactic acid (PLLA): a biostimulator that gradually rebuilds collagen over time. Results last up to 2 years (Sculptra).
  • PMMA: semi-permanent, lasting up to 5 years (Bellafill). Best reserved for stable, low-movement areas.

Both treatments carry minimal risk when performed by a board-certified dermatologist. According to Cleveland Clinic, fewer than 1% of patients experience significant side effects.

Can You Get Botox® and Fillers at the Same Time?

Yes, and it’s common! Because Botox® and dermal fillers target different types of wrinkles, combining them in one appointment can address both expression lines and volume loss together. Many patients use this approach to achieve a non-surgical “liquid facelift” effect. Your dermatologist will advise on the right combination for your goals.

Which One Is Right for You?

  • Expression lines (forehead, crow’s feet, frown lines) → Botox®
  • Volume loss, hollow cheeks, thin lips, deep static lines → Dermal fillers treatment
  • Both → Botox® and dermal fillers together
  • Non-surgical lift or jawline contour → Dermal fillers for face lift effect

The right answer depends on your face and what you want to achieve. A consultation is the best first step.

At Darabi Dermatology, we take a personalized approach to every injectable treatment—no cookie-cutter plans, no pressure. Just honest guidance from a board-certified expert.


Frequently Asked Questions About Botox® and Dermal Fillers

How long do dermal fillers last?

It depends on the type and location. Per the Cunningham Clinic, HA fillers typically last 6–18 months; CaHA fillers 12–18 months; PLLA fillers up to 2 years. High-movement areas like the lips break down filler faster than lower-movement areas like the cheeks or jawline.

What is the dermal fillers price range?

Per American Society of Plastic Surgeons data, HA fillers average approximately $715 per syringe and non-HA fillers average approximately $901. Most treatments require 1–4 syringes depending on the area and goals. Provider expertise and location also affect cost.

What are the pros and cons of dermal fillers?

Pros: immediate results, minimal downtime, long-lasting, reversible (HA).
Cons: temporary and require maintenance, cost accumulates over time, and rare complications can occur if performed by an unqualified injector. Always see a board-certified dermatologist.

Are dermal fillers good for cheeks?

Yes! Dermal fillers for the cheeks are one of the most popular and longest-lasting treatments, typically lasting 12–24 months. HA and CaHA fillers are most commonly used to restore volume and lift in this area.

Are Botox® and fillers safe?

Both are well-established, FDA-approved treatments with strong safety profiles. Fewer than 1% of patients experience significant side effects when treated by a qualified provider. Board certification matters—it’s the clearest signal of training, skill, and safety standards.
