Abstract
An applicator for dispensing compositions includes a crushable ampoule covered with a barrier material that serves as a protective barrier. The applicator can also include a body made of a flexible material that holds at least one crushable ampoule. The protective barrier protects the user's fingers from puncture by shards created during breakage of the crushable ampoule.
