BOTOX works in a way that once injected, the skin will appear smoother and softer because the solution is a muscle relaxant. It freezes the muscles beneath the skin where it was injected. However, it doesn’t add any volume to the area. Belotero, like other injectable dermal fillers, can provide the same results as BOTOX, but works in a way that it adds more volume so that it stretches the skin to make it appear more youthful and smoother with wrinkles becoming less evident.
