While both Botox and dermal fillers are effective for wrinkle reduction, they work differently. Botox relaxes the muscles that cause wrinkles due to facial expressions, making it ideal for dynamic wrinkles like crow's feet and forehead lines. Dermal fillers, on the other hand, add volume to the skin and are best suited for static wrinkles and deeper folds. Often, a combination of both treatments is used for a comprehensive anti-aging approach throughout the face.
