Side effects on the skin and eyes If you have a reaction to a chemical used during the process, you may experience side effects within two to three days. Bloodshot eyes can last one day, others up to two or even four days. Bloodshot eyes after eyelash extensions are usually due to sensitivity to adhesive formaldehyde vapors or an allergic reaction. The vapors of the adhesive may come into contact with the mucous membrane if the eyelash stylist does not properly cover the lower row of eyelashes or strongly lifts the upper eyelid during treatment.
Both eyelash stylists and clients should recognize the cause of eye redness after eyelash extensions in order to properly plan the next steps. If the eyelash stylist places them directly on the skin of the eyelids or on the roots, the extensions can damage the mucous membrane. Burnt eyelash extensions suggest that the customer is slightly sensitive to uncured adhesive vapors that can be released from the joints when they get wet and this causes itching. Below is a table that summarizes the main differences between a chemical burn and an allergic reaction caused by eyelash extensions.
If you notice any signs of swelling or pain around your eyes after you put on your eyelash extensions, ask your eyelash stylist to remove them and contact a doctor right away. In case of complications, the eye doctor will most likely recommend removing the eyelash extensions.
