Looking for advice from an older person on fading beauty

I look forward to this pressure being lifted, being so young looks are importantly to me and society. When you get older (55-90) how does your mindset shift ? Do you mourn your young looks? Is it sad? Sorry to be so superficial, it’s just something that weighs on my mind. I know beauty is much more, but i feel like when i get way older I will be very depressed but i’m hoping by then my mind will be much more mature and rational
