We love seeing our fave celebs using their social media influence to support a good cause — and Zac Efron is no different.

The actor posted an Instagram photo with a pink nail, and the reason? To bring an end to child abuse.

Chris Hemsworth nominated Efron, and other celebs to become a @PolishedMan and support the end of child abuse.

Efron explained in his caption that “1 in 5 children are subject to physical and/or sexual violence before the age of 18 and that’s one too many.”
