An Art form I believe.
Botox has both a good and a bad name. It can be used well and poorly. It is a toxin, botulinum toxin that paralysis muscles that are tending to overwork and create wrinkles. A small dose of botox is called baby botox and renders a very natural subtle youthening look smoothing out fine lines and divets in the ageing forhead.
Filler works like a charm in the cheek zone to lift : jowls, marrionette lines and generally also a youthening effect. Filler also really does wonders for very thin lips and uneven lips or if you really are wanting a pout.
So yes it does make you younger but if you do it in small doses it is subtle and smoothing and just very pretty.
And an art.
