Brow care for perimenopause & beyond
Your brows changed. Your confidence doesn’t have to
Shifting hormones in your 40s and 50s, plus years of overplucking, can leave brows looking sparse through the arch and thin at the tail. NULASTIN® BROW Shape Altering Serum is powered by Elastaplex® Technology, our proprietary blend of elastin and signal peptides made to support the look of fuller, more defined brows from the root.

What your brows need now
Brows after 40 deserve more than a conditioner
Oils and conditioners help the brow hairs you already have look soft and glossy. They are a lovely step. But when years of tweezing and life’s hormonal shifts leave brows looking sparse, NULASTIN® takes a different approach.
Elastin is the protein that helps anchor hair at the root, and natural production slows as we age. Elastaplex® Technology brings Elastin Replenishment™ to your Elastin Root® System and pairs it with signal peptides, so brows look fuller and more defined with consistent use.

From our founder“I built NULASTIN® because I refused to accept that aging meant disappearing”
“Like so many women, I reached my 50s and watched my brows thin and fade. We were told to microblade, pencil or simply accept it. Elastin Replenishment™ changed how I think about brows. You don’t need the brows you had at 20. You deserve to see yourself in the mirror again.”

Your questions, answered
What women ask us most
Will it work if I overplucked for years?
Many of our customers start NULASTIN® BROW after years of tweezing. Most see results within 6 to 12 weeks of consistent use. Brows that were overplucked for a long time may take longer, up to 6 months. Results vary from person to person.
Is it gentle enough for the eye area?
NULASTIN® BROW is dermatologist tested. Use the spoolie to brush serum onto your brows only, keeping it away from your eyes and eyelids. Because the formula contains a prostaglandin analog, please read the usage disclosure below and talk with your doctor if you have questions.
What about coarse or silver brow hairs?
Keratin in the formula helps coarse or silver hairs look smoother and lie flatter, so they blend softly with the rest of your brow.
Can I wear my usual brow makeup?
Yes. Once the serum feels dry to the touch, apply your favorite pencil, powder or gel.
Do I need to use it forever?
Consistency keeps your results. Once you love your brows, many women move to once a day or a few times a week to maintain them.
