BOTOX® vs. Dermal Fillers: What's the Difference and Which Do You Need?

Are you wondering about the difference between BOTOX and fillers, and which treatment is right for your concerns? BOTOX relaxes muscles to smooth dynamic wrinkles, such as fine lines around the eyes, while dermal fillers add volume to areas like nasolabial folds and hollow cheeks. 

 At Scottsdale Plastic Surgeons in Scottsdale, AZ, Dr. Paul K. Holden helps patients understand how to get rid of wrinkles with the right cosmetic injectables. If you're ready to explore your options, call now to schedule a consultation. 

BOTOX: Reduce muscle activity 

BOTOX is a popular treatment that relaxes the muscles responsible for creating wrinkles. When injected into areas like the forehead, between the brows, or around the eyes, it reduces muscle activity and smoothes the overlying skin. This makes it great for treating dynamic wrinkles, which form from making repeated facial expressions, like smiling or frowning. 

Common areas treated with BOTOX include forehead lines, frown lines, and fine lines around the eyes (often called Crow's feet). Results appear within a few days and can help you achieve smoother, more refreshed skin without surgery or downtime. 

Dermal fillers: Restore volume 

Dermal fillers are gel-based injectables, often made from hyaluronic acid (HA), that add volume beneath the skin. Unlike BOTOX, which relaxes muscles, fillers physically fill in areas that have lost fullness over time. They're ideal for treating static wrinkles and volume loss in areas like the cheeks, lips, under the eyes, and nasolabial folds. 

Fillers restore structure, smooth away creases, and create a more youthful contour. They're commonly used to plump thinning lips, lift hollow cheeks, and soften deep lines. Results are immediate and can last a long time, depending on the product and area treated. 

What happens during an appointment 

During a consultation at Scottsdale Plastic Surgeons in Scottsdale, AZ, Dr. Holden will assess your facial features and discuss your cosmetic concerns. We explain the difference between BOTOX and fillers and recommend which cosmetic injectables are suited for your goals. 

No matter which you choose, treatment is considered quick and relatively comfortable. A topical numbing cream may be applied beforehand, and the injections are performed using a fine needle. Most sessions take about 15 – 30 minutes, and you can return to your normal activities right away. 

Some minor swelling or bruising may occur afterward, but these effects typically fade within a few days. Dr. Holden will provide aftercare instructions to help you get the best results possible. 

How long do cosmetic injectables last? 

BOTOX results typically last 3 - 4 months. As the effects slowly wear off, muscle activity returns, and lines may begin to reappear. Regular treatments help maintain smooth skin over time. 

Dermal fillers last longer, with results ranging from six months to two years. Areas with more movement, like the lips, tend to break down filler faster than areas like the cheeks. Dr. Holden will work with you to create a maintenance plan that keeps your results consistent.
