It is very expensive and now its price is prohibitive. It strengthens the nails but there is also other keratin on the market that is cheaper and equally effective. It is really a shame to sell it for so much!

I pulled off a gel polish and along with it came a layer of my nail, and my nails were completely tragic and thin...
My beautician recommended it to me and I really think it worked wonders... I thought it was like a hardening nail polish but it's an oil. I applied it 3-4 times a day at first and my nails recovered in a week. I repeat, my nails were very thin, I would feel pain from simple movements or when they touched something. After a week, they had resistance, they were healthier, fuller. I recommend it...

I bought it after searching for hardeners and having used mavala and peggy sage, which I was satisfied with. This product, after correct use for 2 weeks, did something different to my nails, it hardened, cleaned, and lengthened (don't expect miracles). My nails are generally like paper, without me particularly bothering them with semi-permanent dyes. It's worth trying!

Perfect product with very immediate, visible results. My nails strengthened from the first week of use. I will definitely buy it again!

I am a professional and decided to try it because I have tried various treatments for my nails. It is the best thing I have ever put on my nails. From the first day, I applied it three times a day and massaged my nails and cuticles, and they immediately hardened. I should note that my nails are naturally very thin and, in addition, I had not left my nails without any material for about three years. So they were very damaged. It's incredible.

It is as effective as a nail oil can be. I did not notice a remarkable strengthening as it promises.

What can I tell you with 3 applications per day since it is an oil I put on my nails from a drop and I massaged it to let it absorb, I didn't see any difference.. maybe I tried it for only 15 days and then I did 2 gel manicures in a row and my nails are in a terrible condition :(

I learned about this treatment from my nail artist. It is a pure liquid keratin without any irritating factors. She told me that it even closes small wounds on the skin, and I didn't really believe it. I used it a few days later (careful, I'm not saying you should do it too, I'm just saying what I did) on a deep cut from a household knife on my palm that wasn't healing easily, and within two days it had nourished dramatically. As a nail treatment, it's unbeatable. No comparison to others that contain formaldehyde.
