A cosmetic doctor who faced a backlash over a video picking apart pop star Troye Sivan's appearance says he 'feels terrible' for upsetting the singer - but will continue to post.

London-based Dr Zayn Khalid Majeed posted a two-minute clip drawing attention to the 30-year-old's 'problem' areas following an appearance at a recent event in Australia.

Fans criticised the 'unsolicited' advice, and the singer himself responded with an essay explaining how the video had triggered long-held insecurities about his body.

Since deleting the video and contacting Sivan to apologise, Majeed tells BBC Newsbeat he will try to make a more positive impact with his content.

Sivan, whose career began when he was a teenager, is regarded by many as a poster boy for the 'twink' look.

The term refers to younger, slim gay men with a boyish look, and Sivan's image appears prominently in Google results and on Wikipedia's definition page.

In the video, Majeed compared studio images of the singer with recent footage, noting signs of 'twink death'.

Majeed pointed to several 'problem areas', such as shadows and 'volume loss' in Sivan's face, and suggested various cosmetic 'improvements'.

People on social media and fans of Sivan criticized Majeed's 'unsolicited' advice on ways to 'retwinkify' himself.

After receiving feedback, Majeed deleted the videos and Sivan later updated his blog to say there were 'no hard feelings from [his] side'.

Majeed reflected on the situation, noting he doesn't want to contribute to the 'negative beauty standards' that people face.

He acknowledged the need to educate and inform people, especially regarding surgery and beauty in a body-positive manner.

Despite the backlash, Majeed maintains that he will continue to analyze celebrity faces, believing there's a strong viewer interest in this content.
