Millie revealed it was all about 'enhancing what's already there'.

She penned: 'Whenever I do a Q&A I am always flooded with questions about which beauty treatments I recommend. 

'I am really interested in cutting edge technology and for me it’s enhancing what’s already there. It’s not about drastically changing my appearance, but more about boosting my confidence and feeling like the best version of myself. 

'I’ve always believed in being completely transparent when it comes to which tweakments I've had, because it’s important to me to be honest about what goes on behind the scenes.
