I have personally been injecting Botox for aesthetic reasons since 1991 and have been using microneedling for over twenty years. Each is an excellent and efficient aesthetic treatment modality, but only if used for the right purposes. Professional microneedling works best for improving superficial color and texture problems, such as mild hyperpigmentation or reddish patches and for textural problems, such as skin roughness or very superficial acne scars. Botox ( as well as the other approved neuromodulators, such as Dysport, Xeomin and Juveau) work best for quieting the muscular hyperactivity of the muscles of facial expression that gives rise to forehead furrows and glabellar frown (scowl) lines. So, if your problem is deep furrows of the forehead that result from hyperdynamic frontalis (forehead) muscles, Botox would be the way to go. And, if, after years of making these furrows day in and day out, to the point that the furrows are now present at rest (static wrinkles), as well, then additionally using a filler, would help to smooth these. You would do well to consult with a board certified aesthetic physician and make sure to ask to see his/her personal before and after photos before agreeing to proceed. Best of luck to you.
