I'm 47, have had one fraxel treatment to my neck and feel as if six months later my neck looks much worse.
I don't know what is worse about the neck because you don't show before pictures and don't describe what you think is worse. Possible side effects from the treatment would be PIH, post inflammatory hyperpigmentation. Other than that, I've not seen worsening of wrinkles, skin tone or quality with the Fraxel laser.
