Wrinkles are the result of sun damage, collagen loss and repeated muscle contractions.
Botox (Botulinum toxin) is injected to relax the muscle.
Fillers are used to restore volume and contours.
The main cause for wrinkles is sun damage, leading to collagen loss. Repeated muscle movements with your facial expressions result in wrinkles. These dynamic wrinkles appear and immediately disappear when we are young. Over time the skin can’t relax fully anymore and static wrinkles appear. A typical example are the frown lines.
Botox
Botox is a neurotoxin and blocks the neural transmission and contraction of the muscles. The muscle relaxes, wrinkles don’t form or smoothen.
How much Botox is injected determines how much residual movement remains. It can also be used preventatively to avoid lines in the first place.
Filler
The purpose of a filler is to restore volume and contours. Fillers consist of cross-linked hyaluronic acid and are used for deep wrinkles by padding them from below and adding volume.
They are used, for example, for pronounced laugh lines (nasolabial folds) and loss of volume in the cheeks.
