The Greek goddess Aphrodite was, well, a goddess. I don't recall her specifically having the power to become young again in any legends, because she didn't really need to... as a goddess, she was eternally youthful.
Aphrodite caused the beautiful young man, Narcissus, to fall in love with himself.

Artemis is the goddess of the hunt, wild animals, wilderness, childbirth, virginity, fertility, young girls, and disease in women. Aphrodite is the goddess of love, sexuality, and beauty. Artemis and Aphrodite are nearly opposites. They stand for different things.
Aphrodite was a Greek goddess. She was a gorgeous, perfect, eternally young woman She had potent sexual attractiveness & dazzling beauty. She was a daughter of Zeus the King of the Gods
It was a young man, brave but foolish man named Adonis.
Hebe was the goddess of youth and the cupbearer of the gods who served ambrosia at the heavenly feast. She was also the patron goddess of the young bride and an attendant of the goddess Aphrodite, she later married Herakles. She is noted for making the old young again and may be the sorce of the youth of the Olympian gods and goddesses.
Aphrodite was Adonis' lover. Perhaps Aphrodite's best known lover was Ares, god of war, who was also her husband (at least in later versions), but is also reported to have had a go with the handsome young Adonis, who was not a god. She had to compete with Persephone, queen of the underworld, on that one.
