Dr Yi and colleague Dr Hu Weifeng made headlines when their skin tone suddenly darkened after testing positive for coronavirus.
Originally, medics thought the men's organs had been damaged during the battle to save their lives.
It was thought that iron, which should have been stored in their liver, had flooded their blood vessels instead, as the organ was not working properly.
These rising levels could thus change skin tone and increase facial pigmentation.
However spokesperson has now confirmed the abnormal skin change was caused by an antibiotic used during the course of their treatment.
The doctors, both aged 42, contracted the COVID-19 while treating patients at the Wuhan Central Hospital nearly four months ago.
They are colleagues with late whistle-blower Li Wenliang, who was reprimanded by police for first warning of the deadly coronavirus, before tragically dying at the hands of the disease on February 7.
Footage released by a Beijing TV Station shows Dr Yi and Dr Hu lying in their hospital beds with notably darker skin on April 6.
Incredibly, a photo taken of Dr Yi on May 9 now shows the medic almost looking like his former self.
Prof Duan Jun, the deputy director of the Department of Critical Care Medicine at China-Japan Friendship Hospital, said the medical team had administered Polymyxin B, a last-resort antibiotic, during the doctors’ treatment.
He said the drug had caused hyper-pigmentation in the doctors' body, but the condition would slowly disappear as they recovered.
Dr Yi, a cardiologist, saw his condition improved after doctors had hooked him to a life-support machine called ECMO for 39 days.
Speaking to CCTV from his hospital bed on April 20, Dr Yi said he had mostly recovered.
He said he could move in bed normally, but was still struggling to walk independently.
Dr Yi confessed that the ordeal of battling the deadly disease had given him “nightmares.”
He told a reporter: “When I first gained conscious, especially after I got to know about my condition, I felt scared. I had nightmares often.”
Dr Hu, a urologist, had been bed-bound for 99 days with COVID-19 and is still recovering in hospital.
The medics treating him said his overall health was weak, while Dr Li said he was worried about his colleague’s mental health.
Researchers have warned coronavirus survivors they may suffer damage to major organs or even develop PTSD.
An article in Science said that it was "too early" to say what lingering effects discharged patients may suffer further down the track.
And Dr Harlan Krumholz, a Yale University cardiologist, told the Los Angeles Times: "COVID-19 is not just a respiratory disorder.
"It can affect the heart, the liver, the kidneys, the brain, the endocrine (glands) system and the blood system."
