Enhance your eyes with the most natural looking semi-permanent extensions. When applied properly, eyelash extensions will last the length of the natural growth cycle of your eyelashes. These semi-permanent lashes will last for at least 4– 8 weeks and they come in a variety of lengths & colors. After the first 24 hours you may swim and shower without worries. They feel so natural that you may forget that you have them on because each individual synthetic lash is attached with surgical glue on each one of your natural lashes.
