Young trans people are bravely sharing images documenting breakthrough moments in their transitions.
The hashtag #MomentsInTransition is home to inspirational stories from across the world.
Canadian Gabrielle Diana started the trend, and told HuffPost UK: "I'm really taken by surprise at how many people have come on board and been part of the movement."
Many people allowed their images to speak for themselves, highlighting the changes they've experienced during their transitions.
Trans food writer Jack Monroe also joined the hashtag, proudly posting the moments that made them feel amazing.
The hashtag coincided with International Transgender Day of Visibility on Thursday.
The day is dedicated to celebrating transgender people, and raising awareness of the discrimination faced by trans people across the world.
