Diamond Nail Hardener Sophin Diamond Defense

Best nail strengthener!! Just wow effect!! I use it after removing gel polish, and when applied in 2 layers, my nails become strong and don't chip. They also grow quickly, and as a bonus, the strengthener dries quickly and stays on for a week. I will definitely order more.

I am completely satisfied with the product! The nail polish dries quickly and strengthens the nail well with just two coats. It doesn't chip off after washing dishes or taking a shower.

I have been using this product for about 2 months. I haven't noticed any special healing effects. I use it as a base for nail polish.

Pros:
1. It has a liquid consistency.
2. It gives a nice shine.
3. It has a good formula (without formaldehyde!!!).
4. It doesn't make the nails yellow after use.

Cons:
1. I don't see the claimed healing functions.
2. The smell of silicone glue is terrible!!!! Even the product in the jar looks like silicone glue or starch. Because of this, I won't buy it again.
3. It doesn't prolong the "life of the polish" on the nails.

I am still in search of the perfect base or nail treatment.

Conclusion: This product has a better formula than most expensive brands that contain formaldehyde (Mavala, even OPI) and cheaper ones (Eveline, Korablik), but its strong smell makes me reconsider.

I agree with the previous review. It dries quickly, which is crucial, and it lasts. I use it both on its own and as a base for colored nail polish.

I have been using it for about a month and I am completely satisfied. It is easy to apply and dries quickly. There is no strong odor. It lasts a long time on my nails (although generally, no nail polish stays on my nails for more than 2 days). It does not dry out my nails, they do not chip and grow quickly.

I have been regularly using this product for over two months. It is pleasant to use - the brush is convenient, it dries quickly, and it stays on the nails for a long time. It can be used both as a standalone coating and as a base for nail polish. With this product, my nails look well-groomed. However, it does not fulfill its promise of strengthening the nails. On the contrary, after two months of use, my nails are peeling even more, and I cannot even grow one millimeter now. I have to file them down to zero, and they break easily. I have decided to stop using it.

The nails become stronger, but the tips still peel off. Apart from that, I am satisfied with the product. It is easy to apply and can be used as a base for nail polish.

With this nail strengthener, I indulged myself in the luxury of having a few extra millimeters of nail growth. Usually, due to their softness and brittleness, I have to file them down to avoid painful breakages. I am satisfied with this purchase.

I have recently started using this product. It's not bad so far. I rated it 4 out of 5 because I'm not sure if this is the final effect after such a short period of time. My nails do feel stronger with it, although they still tend to peel, but that might be more of a personal issue since I had gel nails before and my natural nails were always very soft. It lasts for a few days, which is already good enough for me. I would be willing to try something else as well.

This brush is convenient, dries quickly on the nails, provides a beautiful glossy finish, and lasts a long time. I have been using it for 10 days and applied it three times. Today, the nail technician removed the coating before the manicure and noticed that my nails look healthier. I did not expect such visible results in such a short period of time. I highly recommend it.
