No. I am often asked ‘are eyelash extensions painful?’ and the answer is no – not if applied properly! The eyelash extensions are applied directly to the eyelash, so there is no contact with the skin. It may feel a little unusual the first time, but once you get used to it, it should be so comfortable that you may drift off to sleep! Lady Lash uses high quality relatively fume free glue, which does not burn or sting, unlike cheaper products. People with extremely sensitive eyes or sinus problems may get some watering and slight stinging at the end, but this subsides within seconds.
