Selfies tend to get a bad rep [1], but they can be used for good. For example, take Jamie Raines, a 21-year-old British guy who took a selfie every day for three years to document something very important — the changes in his appearance as he took testosterone. Jamie is a YouTuber with over 9,000 subscribers [2], and he often vlogs about his experiences as a young transgender man. He turned his many photos into a beautiful short film, which the UK's Channel 4 news is going to include in a documentary.

Jamie spoke with BuzzFeed News [3] about his transition and his reasons for documenting it through daily selfies. "I'm very happy with what I see in the mirror and very grateful for how I look now," he said. Watch his transformation and then see how another transgender teen felt the first time [4] she received her first dose of hormones.
