Continuous use for 2 weeks on nails without any previous technical work. I got it to strengthen my nails from the daily wear and tear of housework. No improvement. Maybe the color became a bit clearer. Nothing more. I do not recommend it.

I am not at all satisfied. It does not do what it promises. After using it for a while, my nails show no improvement

Excellent! It helped a lot with recovery after artificial nails with acrylic. Very easy to use, there is no waiting for drying, it dries in a few seconds.

Excellent product!!!!! I had tried a bunch of products (and spent a lot of money) and this one repairs and strengthens my nails day by day!!!! I've been using it for 2 weeks and I keep going...the difference is big and obvious on my nails that were as weak as cigarette paper. Buy it without hesitation.....

It's like putting water on your nails. It does absolutely nothing. The only treatment that really works is CND RescueRxx.

Miraculous. My nails were very damaged from continuous semi-permanent polish and acrylic removal. In 3 days they started to grow, hardened, the peeling stopped, and gradually new nail was built where there was damage and dents. It just doesn't need only 2 applications per day; for faster results, it needs to be applied continuously after every hand wash

I saw results, it restored my nails that were in bad condition after years of semi-permanent that had started to peel and break

My nails had become a mess from the semi-permanent as usual. The only product I have tried that actually improved my nails.

Incredible! From the first application, I saw a difference. I kept looking at my nails in the light to see if it was just my imagination. It immediately fixed the "dents" from the wheel

I used it for 10 days as my nails were in very bad condition. While during the use I did see a difference in the hardness of the nails, after the end of the treatment the result did not last. I give it 4 stars because it is indeed better than those available (I have tried quite a few) but it does not reach the effectiveness of the old ones with formaldehyde...

The product is perfect! It made my nails hard and they don't break! It also dries immediately and doesn't leave any strange feeling! It doesn't sting either. It cools slightly upon application and then you don't even realize you put it on! It lasts forever! And because it's a treatment and you do it for 7 days and then stop, it definitely lasts for months!! It's definitely worth the money!

Truly miraculous. It saved me. It's the only thing that made a difference to my nails and really from the first week of application it had results. I highly recommend it.

There is no better treatment for weak nails. Before, my nails were extremely thin and brittle, after years of using gel. Now they are strong and resilient, so much so that with just regular polish they give the impression of gel/acrylic. Just be careful not to let it come into contact with cuticles because it will work on those too!

after trying everything else, I had almost given up! my nails were thin and breaking. this product is the only thing that helped. it soaks into the nail within seconds.. it's not a coat on top of the nail.

Due to years of using semi-permanent nail polish, my nails started to lift from my fingers. The white part of the nails began to grow towards the nail. It absorbs immediately. It doesn't shine at all. I can say that with proper use they were saved. Only positives.

Very good! I saw a difference immediately in my nails! If you do it meticulously with the instructions it says, the nails are completely different in a week! No other treatment had helped me until now!

I'm not sure if it works miracles.

It dries quickly, nails do look harder and after just one use, however, I noticed that they became very dry and started peeling.

The best thing I have ever used. Even better than nail envy. It's like it fixes from the inside out. It's not a strengthening product but a repair one. I used it on very damaged nails (to the point of pain...) from continuous removal of artificial nails and it literally rebuilt them. On a friend who only had a few dents on the surface (from a wheel), it smoothed them out. I highly recommend it.

After first struggling for a month with an unrelated product that the technician who does my semi-permanent recommended to me, which did nothing (my nails were in bad condition from the removal wheel), I bought this and after 2 days of use, my nails are very different! Wonderful.

The product did not deliver on its promises for me. My nails did not harden and it did not prevent them from breaking or bending when I do chores. I wasted my money on useless carpets again

Excellent product!
After continuous applications of acrylic manicure, my nails had become very weak! From the second day, I saw a big difference! They hardened and grew longer without breaking!! I highly recommend it
