NULASTIN LASH Follicle Fortifying Serum is highly recommended for individuals with eyelash extensions and lash lifts.  Lash extensions and lifts can wreak havoc on your natural lashes. We have found that daily application of our oil-free Follicle Fortifying Serum helps maintain the integrity of your real eyelashes.  There is no evidence that our serum will fade tinted lashes or tattoos.
