Frequently Asked Questions

Got a question about NULASTIN® LASH serum? The answer may be right here or you can check our full list of FAQs.

All of our products are designed for ease of use and can be applied under makeup with little or no wait time. For best results, use twice daily to clean, dry eyes and/or skin.

Consistency is the key to lasting results, but don’t stress out if you skip an application. If you do miss a few days, just start back up and use daily as directed. We don’t recommend trying to “catch up” with a loading dose or duplicate applications for our LASH, BROW, or HAIR products. Our skin care products can be used as much as desired—multiple times daily.

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

This set features our most advanced science yet. Powered by next generation technology, they’re the formulas you know and trust, now with even more elastin support and our latest advancements in peptide science.
