It doesn't fade nearly as quickly as you, in particular, would like to think. If you have good facial symmetry, straight teeth, good skin, all your hair, etc, this will continue to yield benefits literally throughout life, assuming you don't catastrophically fail to maintain it. The same is true for athletic ability / fitness in the sense that people like to say "it will fade", but the reality is that it provides a ton of benefits well into the 60s barring catastrophic injury.
