I feel the need to compare gene editing plastic surgery. Today, plastic surgery is only performed on the very young when a deformity keeps them from functioning normally. Plastic surgery performed for purely aesthetic reasons is typically reserved for adults who can make informed decisions and give consent. I think gene editing  when necessary editing will be performed early on and elected editing will be open to consenting adults
