The style/strategy of their feed posts are very similar to the Consultant Clinic - basically these clinics adopt a holier-than-thou stance of how they take a scientific approach to aesthetics, often showcasing how they've fixed people's botched filler and only posting clients who have a natural look. But often these clinics are just as shady (e.g. the Consultant Clinic photoshop their pics & lies about the credentials of their injectors). If you compare this Essex clinic with the Consultant Clinic their social media strategy is so similar - only posting pictures of natural-looking work, but their Instagram highlights tell a different story. Looking at the Essex clinic's 'client selfies' highlight, there's women with filler which has migrated to their upper lip who absolutely should not have been allowed to get additional filler and any injector worth their salt would refuse to inject more.
It's unfortunate because you can see how people would get lured into a clinic like this because they look super professional. But it's just a smart social media strategy.
