, has shared a video documenting what her skin looks like before and after applying makeup using a microscope - and it's super insightful.
Tina first gave us a peek at her skin without a speck of makeup on and while on first glance, her skin looks smooth and pimple-free, she explains that it's a different story under the microscope.
As she scans over her skin, she shows her viewers her under-the-skin spots, hairs and freckles and they look crazy different close-up.
Here's her pimple before makeup..
And here it is under the microscope after she's applied her makeup...
Indeed, Yong herself likened the microscopic view of her mascara-clad lashes to the charred remains of a burned down forest.
Here they are before the mascara was applied...
And here they are after... Woah!
Viewers took to the comments section in their droves to comment on the video, with one writing: "I had to pause the video to go wash and shave my face haha, great stuff."
"This video is great. It’s so weird how hair makeup and beauty is so glamorous but looks absolutely weird under a microscope," another added.
