Why we stand behind it

This nail treatment utilizes biodiffusion technology, the same molecule used in epres hair products, to provide fast and microscopically proven repair to your nails. Nails and hair are both made of keratin, but nails are far more cross-linked than hair. When you damage a nail, you damage more bonds, which makes repairing the structure of the nail more difficult. This first-of-its-kind bond repair for nail treatment penetrates the tightly cross-linked bonds in the nail to repair from within, resulting in lasting restoration for brittle, dry, and discolored nails using the highest concentration of only two active and clean ingredients. Most users experience results after just one use and will continue to see noticeable repair over time.

Key ingredients

- Ethyl acetate: an all-natural solvent that helps open the nail, allowing the active ingredient to penetrate.
- Diethylhexyl maleate: patented active oil for repairing disulfide bonds.

What is an undertone?

An undertone is the color beneath the surface of your skin, which never changes (even with a tan). There are three types of undertones:

Pink/Cool

I see red or pink undertones around the perimeter of my face and neck.
My skin burns easily, but barely tans.
My skin looks better in silver jewelry than gold.

Neutral

I see both pink and yellow undertones around the perimeter of my face and neck.
My skin sometimes burns and sometimes tans.
My skin looks good in both gold and silver jewelry.

Yellow/Warm

I see yellow or golden undertones around the perimeter of my face and neck.
My skin rarely burns, but tans easily.
My skin looks better in gold jewelry than silver.

Reviews

Nails are healthy

"My nails have never looked better! I use this to recover my nails after wearing press ons for a few weeks. It works great, for the first time ever I don’t feel the need to cover my nails to hide how damaged they look."

Deanna (5/5)

TBD but liking it so far

"I've been using this daily and I love that it absorbs into the nail so quickly so I can go about my day. Nails definitely feel less brittle!!"

Sam C. (5/5)

saved my nails

"after a few gel manicures and not taking them off properly, my nails were weak- this product saved them"

Siri D. (5/5)

Too soon to tell

"Easy to apply, no harsh scent. Smooth under normal nail polish. I haven’t used this consistently enough to see results yet but so far so good."

ALEXANDRA F. (4/5)

Surprisingly effective!

"I tried this when all else failed. It worked on dry, peeling, crumbling nails. I also keep the cuticles well moisturized."

Mary L. (5/5)

Great Results

"I’ve been using this in my toenails which became very dry after a pedicure. The improvement in my nail condition after two weeks of use is impressive!"

Kathleen L. (5/5)

Not really helping

"I bought this nail treatment in hopes to repair my peeling nails. With the dry weather and copious handwashing of late fall, my nails were peeling at the ends. I don't use gel nails or anything so they weren't damaged that way. It might be a nutrient deficiency , but I thought this looked promising as something topical to help "heal" them. I was looking for a more natural solution than the typical basecoat I'd buy at Target. I've been faithfully applying this horrible smelling stuff to my nails every night for over two weeks and they haven't changed much. It's possible they might be growing faster but that might be the extra zinc I'm taking. Overall I am disappointed in this product. It's very expensive for something that does not smell natural to me and has no effect in strengthening my nails. All that said, maybe it works for other kinds of nail damage?"

AllisonS (2/5)

nail hardener

"Makes my nails so dry and the tips break off"

Lynn T. (3/5)

Not A Winner

"Firstly, I don't know what's up with the reviews on Credo. there are duplacite and triplicate reviews. I was hoping this would help my nails, which have never recovered from the gels I used to wear. This product didn't work. Also the brush feels very cheap."

Emily (2/5)

Buy it

"It works!"
