Amusing quotes from the article:
“[…] Some of the doctors trying out the new technique are reluctant to promote Botox as a treatment for sagging breasts. “I think the best part of the procedure is the posture improvement,” said [a doctor]”
“The injections also tend to make the nipples semi-erect. Dr. Smith believes that Botox is blocking the action of neurotransmitters, or chemical messengers, which would normally retract the nipples.”
