The TikTok video shows a teenage girl in braces applying a series of 14 beauty products to her face, an arsenal that costs nearly $350 all told.

It's one of many such videos where girls share their beauty regimens -- but then something goes wrong.

"This is what my skin looks like. It is very glowy right now, I love it! But also, I just had some allergic reaction to something that I tried, so ignore how red my face is," says the girl, as her skin turns crimson and inflamed.

"I don't know what's happening. But if anybody knows how to get it to stop burning, that would be greatly appreciated, because it actually hurts a lot," the girl tells her audience.
