What's the Difference Between BOTOX® and Dermal Fillers?

If you're thinking about smoothing away wrinkles and fine lines, there's a good chance you've come across BOTOX and dermal fillers. These popular cosmetic injectables both work to enhance your appearance, but they do it in different ways. 

 While BOTOX softens lines caused by facial expressions, like frowning or smiling, dermal fillers add volume to hollow cheeks, nasolabial folds, or other areas that have deflated over time. 

At Keamy Cosmetic in Westborough, MA, Salem, MA, and Naples, FL, we tailor each injectable plan to fit features and goals. Call Dr. Jean Keamy to schedule a consultation and learn how BOTOX and fillers can help you achieve a refreshed, natural look. 

When to choose BOTOX 

BOTOX is ideal for treating dynamic wrinkles that tend to be caused by muscle movements. For example, expressions, such as smiling and laughing, can lead to lines around the eyes. 

BOTOX works by gently relaxing the underlying muscles so the overlying skin can smooth out over time. 

Patients often choose BOTOX to treat:  

  • Forehead lines 
  • Crow's feet 
  • Frown lines (between the brows) 
  • Bunny lines (on the nose) 

Most people see BOTOX results in just a few days, and the effects typically last 3 – 4 months. BOTOX can also help prevent wrinkles and fine lines from getting deeper, making it a great choice for early maintenance as well as more noticeable concerns. 

When fillers are the better option 

If your biggest concern is volume loss, dermal fillers are a go-to solution. These products restore lost fullness to areas that have grown thin due to age or weight loss. Fillers are especially effective for addressing:  

  • Hollow cheeks 
  • Nasolabial folds (smile lines) 
  • Marionette lines (lines around the mouth) 
  • Lip enhancement 
  • Under-eye hollows 

Fillers are made from a gel-like substance, often hyaluronic acid, which works to smooth and plump targeted areas. The results are immediate and can last from 6 months to 2 years, depending on the type of filler involved. 

What if you need both? 

Sometimes, the best results come from combining BOTOX and dermal fillers. These two treatments work together to address both wrinkles caused by movement and volume loss. This approach, called a "liquid facelift," can smooth and lift your features without the need for plastic surgery.
