View this video on YouTube As/Is / Via youtu.be That's exactly why Chloe, Swasti, and Kelsey went to the dermatologist to get tested. BuzzFeed Chloe said she's had eczema her whole life. It was particularly bad on her face when she was younger. BuzzFeed "i think that I just generally have sensitive skin." Kelsey purposely didn't wear makeup to show how her sensitive skin tends to flare up. BuzzFeed She loves beauty products and subscribes to a ton of beauty glam bags, so she wondered if those new products may have had something to do with it. Meanwhile, Swasti said her skin also tended to flare up every now and then. BuzzFeed Not too long ago, she had a nasty reaction to some glue she used for loose glitter on her eyelids. The trio of ladies went to get an allergy patch test at Rapaport Dermatology. BuzzFeed Dr. Vicki Rapaport and Dr. Marvin Rapaport, a father-daughter team, run their practice together. The doctors tested over 40 of the most common kinds of allergens in skin care products, as well as other personal products that each patient brought in. BuzzFeed Then the patches went on their backs for an entire 48 hours to see if they had any sort of reaction to any of these numbers. BuzzFeed The doctors are able to tell what they're allergic to based on how irritated their skin was under each corresponding number. After almost a day, things got super itchy and uncomfortable, guys. Especially for Kelsey and Swasti. BuzzFeed The discomfort was real. The test results revealed Kelsey had very common types of allergies.

Chloe discovered that, besides the eczema she already knew about, she was only allergic to Cobalt. BuzzFeed And Swasti found out she was only allergic to one thing, and it was an antiseptic and antifungal preservative. BuzzFeed Oh, and guess what? After 72 hours of the patch results, they also found out that Swasti was allergic to that glitter glue she had used. Good to know. All the ladies definitely learned a lot about their skin and what types of things they should avoid. BuzzFeed They highly recommend this type of allergy test.
