Disclaimer: I have naturally full lips that I was bullied mercilessly for growing up (fish lips was probably the kindest thing I got) so I’m sort of enjoying the trend as all of a sudden people want to know where I got my amazing lips done! 
However, something I don’t think has been mentioned, is the impact of all of theses cosmetic procedures on child development.
Babies/toddlers/small children need human expression to develop secure attachments and to learn. If our faces are less able to show ‘true’ reactions because they move less due to Botox and fillers, how does this impact on attachment and emotional and social development. How can a baby discern delight from discouragement?
Anecdotally, I have seen an increase in children who are struggling to regulate their emotions (EYFS Teacher in a school) in my cohort of 29 children, the three children with cosmetically enhanced mothers each really struggle with reading other people’s emotions, regulating their own, following boundaries (again related to reading pleasure and displeasure on faces) and resilience. They each really struggle to keep on trying if something goes wrong, and become very upset. They share a lot of the same behavioural traits as the children I have taught who have witnessed domestic violence. To me that is the most concerning factor.
At home time I always pass over a highlight of the child’s day. I know from their words that the mother’s are proud of their children but their faces show nothing. One had suffered a loss of a family member (covid) recently and the only reason I knew to comfort her was her eyes were crying, otherwise her face was emotionless.
It must be incredibly stressful for a small developing mind
. In fact my most enhanced mother’s child cuddles her mum whole heartedly, but never holds eye contact when she is speaking to her. I wonder if the lack of feedback is why.
