A law school friend of mine started getting Botox in our early 30s, despite having almost zero wrinkles.
One of the strongest memories I have of her was when I was visiting her for a few days as a respite break from caring for a friend on hospice status with breast cancer - I was crying and she was saying comforting things, but her face was frozen solid, no empathy there at all. It was the most discomfiting thing.
A few years ago I read an article in the NYT about how Botox interferes with micro expressions and how we experience empathy; I couldn't help but think of my friend who had just had a baby when I visited her and later had another - what is the experience of babies and young children whose mother's faces don't register emotion in response to theirs? I would think it would be disruptive to development and bonding.
Just something to consider if you are considering Botox and have chlidren.
