30 Day Longer Nails Money Back Guarantee

30 Day Longer Nails Money Back Guarantee

Use it daily for thirty days. If your nails do not look longer and stronger than they did on day one, tell us and we will refund you. Nothing to post back.

What is in it, and will it make my nails hard?

No, and that is the point. In the bottle: olive and cottonseed oil, two peptides, vitamin E. No formaldehyde, no hardening resin. It keeps nails flexible, because flexible nails bend instead of snapping.

Can I use it with polish, gel or acrylics?

Yes. On bare nails when you can, and on the cuticle when you cannot. If you are wearing gel or acrylic, keep applying around the edges until they come off.

How do I use it, and is it gentle enough for daily use?

Each morning on clean, dry nails: one coat over the whole nail and the cuticle. Let it sink in before anything else goes on. Oil based, no acetone, no hardener, which is what makes it a daily product.

Where do you ship, and what if it does not work for me?

Worldwide, from our US warehouse through our own dedicated network, so your order lands wherever you are. Orders go out in one to two business days, support answers at any hour. You are covered by the 30 Day Longer Nails Money Back Guarantee. Use it daily for thirty days. If your nails do not look longer and stronger than they did on day one, tell us and we will refund you.

THE PROBLEM

They don't stop growing. They stop surviving.

Acrylics, gel and hardeners all cover the nail or stiffen it. Whether yours thinned under a drill or were always dry and peeling, the nail underneath breaks before it gets long.

01

Acrylic and hard gel need a fill every two to three weeks. The filing and the soak-off are what thin the nail underneath.

02

Nail hardeners make nails rigid. The FDA's own guidance says the formaldehyde ones leave them more brittle with frequent use.

03

Press-ons and glue last a week, and the top layer of the nail often comes away with them.

Lorem ipsum dolor sit amet

how it works

Seal it. Let it bend. Keep the length.

Peptide-Flex Complex™ seals the nail, keeps it flexible and holds it at the free edge. One coat a day: longer in weeks, the full result over 2 to 3 months.

Acrylic and hard gel put a false surface over the nail. Peptide-Flex Complex goes onto the nail itself, cuticle to tip, and sinks in. Gel covers for three weeks and takes moisture out on the way off. This is one coat on clean, dry nails: it seals, it flexes, it holds. Hardeners make the nail rigid. The oils keep it bending, which is what stops the tear at the edge.

Hexapeptide-3 and Myristoyl Pentapeptide-4

Hexapeptide-3 and Myristoyl Pentapeptide-4 - the two peptides Peptide-Flex Complex is built around.

Olive and Cottonseed Oil

Olive and Cottonseed Oil - the seal. A film that slows the water leaving the nail plate.

Vitamin E Acetate

Vitamin E Acetate - keeps the oils stable. No formaldehyde, no toluene, no acetone.

Seal it. Let it bend. Keep the length.

RESULTS TIMELINE

Longer by week three. The full result by month three.

What to expect on one coat a day. The difference is not how fast they grow. It is how much of it survives to the tip.

FAQ

Questions before you buy

How is this different from a nail hardener?

A hardener coats or cross-links the nail until it is rigid, and a rigid nail chips and shatters at the edge. The FDA's own guidance says the formaldehyde ones leave nails more brittle with frequent use. UltraGrow does the opposite: it seals moisture into the plate so the nail stays flexible, and a flexible nail bends instead of snapping. There is no formaldehyde, no toluene and no hardening resin in it.

What is in it?

Six ingredients, and here is the list in full: Purified Water, Hexapeptide-3, Olive Oil, Cottonseed Oil, Vitamin E Acetate, Myristoyl Pentapeptide-4. Two peptides, two oils that do the sealing, and vitamin E to keep those oils stable in the bottle. No parabens, sulfates or artificial fragrance.

Is it gentle enough for daily use?

It is oil based, with no acetone, no hardener and no added fragrance, which is what makes it a daily product rather than a weekly one. Keep it to the nail and the cuticle. If your skin reacts easily, a patch test before your first full application is sensible.

Can I use it under polish or with gel?

Yes. On bare nails it goes straight on. Under polish, let it sink in fully first. If you are wearing gel or acrylic, keep applying it to the cuticle and the skin around the nail until they come off, and start on the whole nail the day they do.

How soon will I see a difference?

Softer cuticles and a smoother, shinier nail in the first week. The first visible change most women report is at three to four weeks, when nail has grown past the tip and stayed there instead of tearing. The full result is the two to three month one, and that is the fair window to judge splitting and peeling.

What happens if I stop?

UltraGrow is a daily conditioner, not a course with an end date. Stop coating and the nail starts losing moisture again, which is when the splitting comes back. Keep it in the routine the way you keep a hand cream in it.

How long does a bottle last, and how much do I need?

About a month at one coat a day, both hands. The full result runs two to three months, which is why the three-bottle is the tier we preselect.

Will it work on toenails?

Yes, the same way. Toenails grow more slowly than fingernails, so give it longer before you judge it.

LONGER NAILS. NO APPOINTMENTS.

Three weeks from now, you stop hiding them.
