Week 4: Your Questions Answered

What if I miss a few days?

Consistency is the key to lasting results, but no worries if things come up. If you 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 and/or duplicate applications for the LASH, BROW, or HAIR products. Our skin care products can be used as much as desired — multiple times daily.

Are NULASTIN products natural, ethical, and safe?

Yes, NULASTIN uses naturally derived, ethically sourced ingredients. All formulas are cruelty-free, paraben-free, gluten-free, vegan-friendly, clinically evaluated, and proven safe. We are free of top common allergy-causing preservatives — including lanolin, topical antibiotics, and MCI/MI.

How is BROW different than other products on the market? 

NULASTIN is the only product used in the cosmetics industry that contains Elastaplex Technology featuring a cruelty-free elastin protein that supports the body's ability to anchor the hair follicle "bulb" to the elastin root system, delivering longer, stronger looking hair, lashes and brows. Our formula has synergistic, active ingredients that target all phases of the hair growth cycle. 

No other formula has our blend of Hepatocyte Growth Factor (HGF) with vegan elastin and keratin proteins that are naturally derived and identical to the corresponding human DNA proteins. Keratins can range in quality and can differ from where they are sourced. Some keratins are made from plants and some from animal by-products. Common animal by-products used by the cosmetic industry are bovine blood plasma, tendons, and ligaments from harvested animals. Our unique, cruelty-free proteins are one of the biggest breakthroughs you’ll find in our formula compared to other brands.
