Well, what about beauty of the soul? Or beauty of the heart? In scripture it says,
"The Lord does not look at the things man looks at. Man looks at the outward appearence, but the Lord looks at the heart." It basically says that God looks at how we are on the inside and not the outside, like the world does. That body without blemish? It doesn't matter to Him. He loves us whether we have acne or not, split ends or no split ends, if our teeth are crooked or straight -- it does not matter to the Lord.
Why do we care about how we look? Because we listen to what man says: "Get this and you'll be wrinkle-free!" "Wear this and everyone will love you!" "Only this hair-dye will make your hair absolutely ravishing!" And the list goes on and on...
How long will those things last? Temporarily. Your hair color will change and fade out, those clothes will go out-of-style, and your wrinkles are still going to be there when you're eighty-something years old.
So what kind of beauty really does last? That of the heart and soul. God tells us time and time again that our outer adornments do not matter, but rather what He sees on the inside.
"Let your beauty not be external - the braiding of hair and wearing of gold jewelry or fine clothes - but the inner person of the heart, the lasting beauty of a gentle and tranquil spirit, which is precious in God's sight." -- 1 Peter 3:3&4
"There could never be more beautiful you."
