In light of Transgender Day of Visibility, Transgender teenagers are showing jaw-dropping photos of their transformation as the hashtag #MomentsInTransition goes viral on Twitter.

Canadian teenager Gabrielle Diana started the hashtag after posting on Instagram about how transitioning had changed her life.

The 17-year-old from told BuzzFeed News she started the hashtag because she wanted transgender people to celebrate their journeys.

“In the trans community I’ve seen a lot of people always looking for what they WANT to be in the future, which is totally understandable,” Gabrielle said.

“I think it’s important to look back on defining moments in our transitions and really give ourself props, because it’s so important that we recognise our hard work and let it really be noticed.”

The hashtag was so successful that it is still going strong, with teens sharing their ‘then and now’ photos with the world, as well as opening up about the mental health battles they have overcome whilst becoming the person they feel they are inside.
