Allergy :: Allergic To Lip Products?

I am 18 years old, and I have never been allergic to anything in my life. As part of my nightly routine, I've always put on lip balm before bed. However, late last year, my lips started to get more dry and chapped than usual, even itchy. They felt like sand paper and often developed tiny bumps. If rubbed hard enough, the bumps would produce a clear liquid. The edges of my lips also sometimes felt very raw and red. These symptoms would last around a week.

At the time, I had been using just plain Burt's Bees Lip Balm for many weeks. When I got the symptoms, I used a bit more of the balm than I usually did, thinking it would work for dryness. When nothing seemed to be working, I stopped using it altogether. In time, my lips healed, and I switched to Softlips lipbalm in both vanilla and peppermint flavors. I showed no reaction from their usage for about a month. Then, I started getting the same reaction that I got from the Burt's Bees Lip Balm. That was when I figured I was developing an allergy to lip balm. Over time, I also realized I was getting the same reaction even faster from lipstick and lipgloss. That meant I was allergic to all lip products across the board.

I began researching into the symptoms and the ingredients in lip products, especially ones that commonly produced allergic reactions. With that knowledge in mind, I've tried many other balms these past months, including ones by Blistex and Kiss my Face. I'm even allergic to plain Chapstick. At first, I would not show any symptoms at all, but they would eventually show up within a few weeks, sometimes days. I even tried alternating the balms every night, which worked slightly but I would eventually get the reaction again. Nowadays, I only wear lip balm every few nights because I can't stand having chapped lips, but never multiple nights in a row. Even then, there's always a chance of my reacting to it.

I haven't been able to pinpoint the exact ingredient that I'm allergic to, and I'm hesitant to spend any more money to try more products. I haven't changed anything about my diet, makeup, facewash, mouthwash, or toothpaste, so I am very certain that it's the lip products. After my research I've also found that other people have had the same problem.

Has any product been found that works but doesn't trigger a reaction from people with my allergies?

I've heard that Vaseline is possibly the only solution, but because of my research I've been staying away from products with petroleum and petrolatum in them. Should I try it out anyway?
