A warm, loving and vibrant person will always be beautiful to those around them, regardless of how they appear on the outside. Those who choose to judge others on physical appearances are hardly worth having as friends.
I'm only 22 but have always taken good care of my skin (staying out of the sun, moisturising etc...) but I look forward to growing older, seeing myself develop as a person in the way nature intended.
I'd rather age with lines on my face from all the smiling I do, than have an artifically line-free face at 70, advertising the fact that I was sucked into the vanity induced society of cosmetic surgery and the need for physical perfection.
