Demodex blepharitis is a condition where tiny mites naturally found on the skin grow out of control along the eyelashes. When this happens, it can cause constant itching, redness and swelling of the eyelids, burning, and flaky, crusty buildup at the base of the lashes.
Wearing false lashes or lash extensions can increase the risk of a mite infestation because they trap oil, debris, and bacteria along the lash line. The glue and added lashes can also make it harder to properly clean the eyelids, creating an environment where mites can thrive and multiply.
Daily lid hygiene is extremely important to prevent and control this problem. Gently cleansing the eyelids every day—especially if you wear eye makeup or false lashes—helps remove oil, debris, and mites before they build up. Tea tree oil–based cleansers and warm compresses are commonly recommended, and in some cases prescription treatments may be required to eliminate the mites. Staying consistent with daily cleansing is the key to keeping your eyelids healthy and preventing flare-ups.
