She posted pictures of herself all made up on her Instagram account.
But there was one problem: The Ukrainian woman's make-up was believed to have been taken from the MH17 crash site.
Ms Ekaterina Parkhomenko first posted a picture of a blue mascara tube.
She then uploaded two selfies which were apparently taken after she had applied the mascara, the New York Daily News reported.
"Mascara from Amsterdam, or rather from the field," Ms Parkhomenko wrote on her social media site. "Well, I think you know what I mean."
Ms Parkhomenko, who is from Torez - close to where the Malaysia Airlines plane was downed in Ukraine, killing 298 people - was then asked by her followers if she was joking and how she got the mascara.
She said she did not collect the make-up herself. "An acquaintance of mine, a looter, gave it to me," she wrote.
The woman, whose age is unknown, described herself as a pro-Russian "separatist".
Her pictures led to an uproar online, the Daily Mail reported.
One Instagram user called her "complete scum" while another commented: "It is sick, completely sick."
Popular Russian blogger Bozhena Rysnka wrote on Facebook: "It is lower than low to pick up mascara from the deceased.
"She's simply an animal, like a dog that gets a pack of biscuits falling from the sky. Can you be angry with a dog for eating it?"
Ms Parkhomenko later deleted her Instagram account. Her last post read: "I am just sick of all this Ukrainian stuff. Sick and terribly furious."
Meanwhile, a Malaysian journalist has been slammed for poking at suspected human remains with a stick at the MH17 crash site.
Mr Khairuddin Mohd Amin, a chief reporter for the Malaysia Gazette news portal, was seen flicking a long, burnt object on the ground with a stick in the video, which was uploaded on Malaysia Gazette's official YouTube channel on Wednesday.
The 2½-minute video came with a blurb that said the skin was of human origin, Malaysiankini reported. It has since been removed, but YouTube users have uploaded copies of the video to the video-sharing site.
"Malaysia can now boast of yet another international achievement - membership in the MH17 Journalism Hall of Shame, for a disgusting violation of privacy in death," journalist Gobind Rudra wrote on his blog Uppercaise on Friday.
