Do you know which injectable smooths fine lines and wrinkles? Where you can inject Botox? What about hyaluronic acid fillers? And why there are so many types?
With today’s wide range of cosmetic injectables, it’s easy to feel overwhelmed. That’s why our expert injectors at Center for Plastic Surgery Ann Arbor created this guide. Think of it as your intro course in injectables. We’ll explain the basics so you can make confident, informed choices while our highly trained team customizes your treatment for natural, beautiful results.
Botox Cosmetic & Dysport
Botox Cosmetic and Dysport are both FDA-approved neurotoxins derived from botulinum toxin type A. They temporarily relax targeted facial muscles to smooth existing lines and prevent new ones.
- Botox Cosmetic was FDA-approved in 2002 and is the most researched neurotoxin in the world.
- Dysport received FDA approval in 2009 and has a slightly different formulation that may act faster or spread more evenly in certain areas.
We offer both options because every patient’s anatomy and goals are unique. After years of in-office testing, our providers have found that Botox and Dysport consistently deliver the most natural, predictable, and long-lasting results for our Ann Arbor patients.
How Do Neurotoxins Work?
Every time you smile, frown, squint, or raise your eyebrows, your facial muscles contract and fold the skin. Over time, those repeated movements lead to fine lines and wrinkles that stick around even when your face is at rest.
Neurotoxins like Botox and Dysport interrupt communication between nerves and muscles by blocking the release of acetylcholine, the chemical messenger that triggers muscle contractions. When those signals are paused, the treated muscles relax, and the overlying skin gradually smooths out.
This process has two major benefits:
- Softening existing lines. You’ll notice smoother skin and a refreshed appearance within days of treatment.
- Preventing new wrinkles. By reducing repetitive muscle movement, neurotoxins help slow the formation of deeper lines over time.
Think of it as pressing a gentle “pause” button on the aging process, without freezing your natural expression. Our injectors use precise technique and dosing to maintain your natural movement while giving your skin a smoother, more youthful look.
Where Is Botox Injected?
Small, precisely placed injections can make a big difference. Botox and Dysport are most often used in areas where expression lines tend to form:
- Forehead lines: Those horizontal lines that appear when you raise your brows.
- Glabellar lines: The “11s” between your eyebrows when you frown or concentrate.
- Crow’s feet: The fine lines that fan out from the corners of your eyes when you smile.
They can also refine and rejuvenate other areas:
- Neck bands (platysmal bands): Soften the vertical lines that can appear with age, giving the neck a smoother, more youthful contour.
- Masseter muscles: Relaxing these muscles can ease teeth grinding and clenching while slimming and softening the jawline.
Our injectors assess your muscle movement, skin quality, and facial balance to determine the ideal placement and dose. The goal is never to erase your expressions, but to keep you looking like yourself, simply more refreshed and confident.
Dermal Fillers
What Are Hyaluronic Acid (HA) Fillers?
As we age, our skin gradually loses its natural stores of hyaluronic acid (HA), collagen, and elastin. These are the building blocks that keep skin smooth, plump, and firm. When they decline, fine lines deepen, cheeks lose volume, and lips appear thinner.
Hyaluronic acid fillers replace what time has taken away. These smooth, gel-like injectables attract and hold moisture beneath the skin’s surface, restoring hydration, volume, and softness for a more youthful appearance.
At the Center for Plastic Surgery Ann Arbor, we use trusted brands such as Juvéderm® and Restylane®, both FDA-approved since 2003 and supported by decades of clinical research. These products are known for their safety, versatility, and natural-looking outcomes.
Here’s why patients and providers love them:
- Instant results: You’ll see improvement right away.
- Hydrating effect: HA attracts water, so your skin appears more supple and radiant.
- Customizable formulas: Different formulations are designed for specific goals, from subtle lip enhancement to cheek contouring.
- Reversible and safe: If needed, HA fillers can be dissolved safely with an enzyme called hyaluronidase.
Results typically last 6 to 18 months, depending on the product, treatment area, and your body’s metabolism. Our injectors take a thoughtful, individualized approach to ensure your results are balanced, natural, and perfectly suited to you.
Why Are There So Many Types of Fillers?
If you’ve ever noticed the long list of filler options, it’s not to make things confusing—it’s to make results precise. Each filler has a unique texture, structure, and purpose, allowing your injector to tailor treatment to your specific features.
Even within a single brand family like Juvéderm or Restylane, formulas vary in density, flexibility, and cohesiveness. These qualities determine how the filler behaves under the skin and how it moves with your facial expressions.
Here’s what those differences mean in simple terms:
- Density (or thickness): Thicker fillers are more structured and “stay put” where they’re placed, which makes them ideal for restoring volume or lift in the cheeks, jawline, or chin. These products act almost like scaffolding, rebuilding youthful contours and definition.
- Flexibility (or elasticity): Softer, more elastic fillers move naturally with your facial expressions. They’re perfect for dynamic areas like the lips, around the eyes, or smile lines, anywhere movement is frequent and subtlety is key.
- Cohesiveness: This refers to how well the filler holds together as a single, smooth gel under the skin. More cohesive products maintain their shape beautifully in areas that need support and definition, such as the chin or midface.
Because every face is different, your injector may combine or layer fillers to achieve the best harmony. At our practice, we consider factors such as how you smile, how light reflects off your skin, and how your features move in motion. The goal is always natural balance and renewed confidence, not overfilled or artificial results.
Where are HA Fillers Used?
One of the biggest benefits of HA fillers is their versatility. They can enhance nearly every area of the face to restore lost volume, refine contours, and soften lines, all without surgery or downtime.
Here are some of the most common treatment areas:
- Lips: Restore volume, define shape, and smooth fine lines around the mouth for a hydrated, natural look.
- Cheeks: Recreate youthful lift and soften shadows, brightening and balancing the entire face.
- Chin and Jawline: Add structure, improve profile balance, and refine the lower face.
- Under-eyes: Reduce hollowness and dark shadows to create a more rested appearance.
- Nasolabial folds and marionette lines: Smooth and subtly lift the folds that run from the nose to the mouth and chin.
- Temples: Restore fullness and support to areas that have hollowed over time.
Each treatment plan is customized to your features and goals. Our injectors often use a layered approach, selecting the right formula for the right area. For example, a soft, flexible filler may be used to smooth fine lines around the mouth, while a thicker, lifting filler adds structure to the cheeks or chin.
Are There Other Types of Injectables?
In addition to neurotoxins and fillers, the Center for Plastic Surgery Ann Arbor offers two other injectables that enhance and complement facial rejuvenation in unique ways. While they don’t replace Botox or fillers, they can be used alongside them for a more comprehensive, natural-looking result.
Sculptra® Aesthetic (poly-L-lactic acid) works by stimulating your body’s own collagen production instead of simply adding volume. Results appear gradually, creating firmer, smoother skin that lasts up to two years. It’s ideal for patients who want subtle, natural improvement over time.
Kybella® is another injectable treatment designed for submental fullness (the “double chin”). Its active ingredient, deoxycholic acid, breaks down and absorbs fat cells under the chin. Once those cells are eliminated, they cannot store fat again. After a series of treatments, patients enjoy a slimmer, more defined jawline without surgery.
The Takeaway
Whether you’re smoothing fine lines with Botox, restoring youthful volume with fillers, or enhancing your contours with Sculptra or Kybella, today’s injectables offer personalized, non-surgical ways to refresh your appearance and feel more confident in your skin.
The best results don’t come from any single product—they come from an experienced injector who understands both anatomy and artistry. At Center for Plastic Surgery Ann Arbor, our team combines advanced training with an artistic eye to create natural, balanced results that fit your goals and lifestyle.
