England has banned botulinum toxin injections – often known as Botox – or dermal lip fillers for girls under 18.
The new law aims to protect young people from harm after years of efforts to regulate the non-surgical beauty industry.
Reports estimates show up to 41,000 Botox-style procedures were carried out on under-18 girls in England last year.
According to the Department of Health and Social Care, there were up to 29,300 dermal filler procedures for under-18s in 2017.
Before the new law, under-18s were able to have Botox-style procedures and dermal fillers.
But with the new ruling, it is expected that Wales and Scotland will also follow suit with similar legislation.
In the UK, practitioners of these procedures do not require certifications or have formal qualifications or training for this type of treatment.
Maria Cutfiled, the minister for patient safety, said she understood the constant pressure for people to look their best, she said: “Far too many people have been left emotionally and physically scarred by their experience, needing medical treatment after botched cosmetic procedures.
“Anyone considering these treatments should take the time to consider the impact on both their physical and mental health and ensure they are using a reputable, safe and qualified practitioner.”
MP Laura Trott, who called for the legislation change in Parliament, said:
“No child needs cosmetic Botox or fillers and from today [Friday] they will no longer be able to walk into a clinic or someone’s home and get a dangerous and unnecessary procedure that could ruin their lives.
“It will not fix the entirety of the problems in this industry, but it will make a real difference for under-18s.”
