For over a year, intimacy was incredibly painful. I was experiencing a persistent burning sensation right at the vaginal entrance that made physical contact almost impossible. My doctor suspected vaginismus and referred me for pelvic floor physiotherapy.

The physiotherapy confirmed that I did have a tight pelvic floor, and I also have endometriosis, which causes pain deeper inside my pelvis and towards the back. But despite months of treatment, the burning at the entrance never improved. I spent a lot of time reading forums, doing pelvic floor exercises, and feeling incredibly frustrated and anxious. It was a really lonely experience.

Then I finally discovered my acrylate allergy. I started checking the ingredient lists of absolutely everything that came into contact with my skin. That's when it hit me: I needed to check my lubricant.

The Culprit: Carbomer

Sure enough, right there on the ingredient list was Carbomer. Also known as polyacrylic acid, carbomer is a synthetic polymer used in most water-based lubricants to give them their thick, slippery gel consistency.

Because my allergy is a delayed hypersensitivity reaction, I never connected the dots. The burning often lasted for days after using the lubricant, making it seem like a muscular or structural problem rather than a reaction to an ingredient. The tissue around the vaginal entrance is incredibly delicate, and in my case, repeated exposure to an acrylate-based ingredient appeared to keep it in a constant state of irritation.

I started trying different lubricants, carefully checking every ingredient list to avoid carbomer and other acrylate-based ingredients. After going through several products, I eventually found one that worked for me.

Within less than a week of switching lubricants, the burning at the vaginal entrance completely disappeared. Neither the pelvic floor physiotherapy nor my later laparoscopy changed that specific symptom. They helped address other issues, but in my particular case, the entrance pain was caused by the lubricant, not by my pelvic floor muscles.

My Safe Alternative: Liquid Silk

Finding a lubricant without carbomer was surprisingly difficult because almost every water-based option I found contained it. I eventually switched to Liquid Silk.

Liquid Silk is a silicone-based formula (ingredients: Cyclomethicone, Dimethiconol, Dimethicone). It contains:

No carbomer
No acrylates
No parabens

It has been a lifesaver. It doesn't cause any irritation, doesn't dry out quickly like many water-based gels, and most importantly, it doesn't trigger the burning. (Note: Silicone lubricants aren't compatible with silicone toys, but for everyday use, it's the safest option I've found.)

I'm not saying that everyone diagnosed with vaginismus or vulvodynia has the same cause. Many people genuinely have pelvic floor dysfunction, nerve pain, or other underlying conditions. In fact, I still have a tight pelvic floor and pain from endometriosis. But if your burning is unexplained, especially if you also react to acrylates in other products, it's worth checking the ingredients in anything that comes into contact with the area. Sometimes the culprit isn't your body—it's something you're putting on it.
