Redness, itching, and irritation
These are common symptoms of a toner allergy. You may notice your skin getting red, itchy, and irritated shortly after using a toner that you're allergic to. This can happen immediately or several hours after usage.
Swelling
In more severe cases, you may observe swelling in the area where the toner was applied. It could range from minor swelling to significant, especially around your eyes, lips, and face.
Rash or hives
Rashes or hives could appear on the skin due to an allergic reaction to a toner. They can be red, blotchy, and often very itchy, causing a great deal of discomfort.
Dryness and flaking
An allergic reaction to toner may cause excessive dryness leading to flaking and peeling skin. This is because the skin may be trying to rid itself of the allergen.
Tightness or burning sensation
A sense of tightness or a burning sensation on the skin could be another sign of a toner allergy. This usually occurs almost immediately after the product has been applied and may be particularly noticeable when trying to open or move the mouth or eyes.
Blisters
In rare, severe cases, a toner allergy could cause blisters on the skin. These can look similar to those caused by severe sunburn and might ooze or crust over.
