For men and women a lot is to do with social and biological reasons I know many young woman in her mid 20s
Would happily date a man in his forties
I also believe there is an element of body dysmorphia with getting bigger and bigger breasts, as implants and lip fillers
The same thing happens with male bodybuilders as well
Also the physical changes do look good on camper and video but not in real life
Some beauty models are also in the older Asia bracket in their 30s are 40s in the case of the kardashians
And older women tend to have finner faces and due to their brand reach they are changing the culture
