I would find a natural looking 35 year old more attractive than a 25 year old with lip fillers/botox or other injectables. I find the look utterly hideous and their faces would be so much more attractive without the shit they pump in to them.
Just about every reality tv show have women that ‘look like that’ and they all morph in to one with puffy cheeks, fish lips, massive white veneers and shiny foreheads.
So in that respect age is irrelevant
