Nulastin - BROW Shape Altering Serum with Elastaplex Technology

Get your brows back. The BROW Shape Altering Serum is Nulastin's top-rated eyebrow serum, clinically proven to visibly restore shape, density, and fullness—without microblading, tinting, or daily penciling.

Powered by Elastaplex® Technology, this formula delivers a proprietary blend of biodesigned proteins and signal peptides directly to the brow follicle. Elastin supplements anchor the follicle, reducing premature shedding. Keratin strengthens the hair structure. A biodesigned hepatocyte growth factor supports the anagen (growth) phase. Together, they rebuild what time, stress, and over-tweezing have taken.

In a 12-week independent clinical study, 100% of participants reported visible brow growth, and 97% noticed their brows appeared fuller.

Results timeline: Elastin activates at the follicle root in weeks 1–3. Visible density improvements typically appear by week 6. The most transformative changes occur between weeks 6 and 12.

How to use: Apply twice daily (AM & PM) to clean, dry brows using short, upward brush strokes with the custom spoolie applicator. Use before makeup, after skincare. One tube is approximately a 5–6 week supply.

Dermatologist tested. Cruelty free. Paraben free. Backed by a 100% Performance Guarantee.

Key ingredients: Biodesigned Elastin (sh-Polypeptide-50), Biodesigned Signal Peptide (Myristoyl Pentapeptide-17), Biodesigned Keratin, Biodesigned Hepatocyte Growth Factor (sh-Polypeptide-62), Biodesigned Isopropyl Cloprostenate.
