Sam and Nic Chapman (make up artist sisters behind Pixiwoo and Real Techniques brushes) have both put a similar post on their Instagram pages, saying they are coming off social media as they've had a good think and decided it's not for them anymore. They will keep their IG accounts but not add any new content. All sounds a bit bizarre since they are regular posters and do a lot of their work on social media, IG especially. Anyone have any thoughts about what's behind it?
