Review: Amazing results! - This stuff was literally an answer to prayer! HIGHLY RECOMMEND! I had been struggling with thin, peeling nails for over a year. I had back-to-back surgeries and my dermatologist told me my damaged nails were probably a result of the anesthesia. (I've never done regular manicures and very rarely polish or gel, so I couldn't blame that.) My nails were so thin they hurt and they would continually split and peel no matter how much I used nail strengthening treatments or polishes. I was at my wits end and tried ordering ISDIN as a last resort. I thought it was a little expensive at the time, but now I believe it was worth every penny! I keep an extra tube on hand now so I never run out. The product and brush are so easy to use. In the beginning I applied it twice a day but tried to keep using it at least once a day for two months. Now that my nails have improved I use it about every 1-2 days. The product is easy to apply and dries and disappears very quickly. I was worried it would be messy and sticky but it is not at all. Sometimes it takes one click per nail to get it going, but sometimes one click will treat a few fingers. A little goes a long way and you will get the feel of it. The product does take time to work. It was 2 months before I had a complete nail grow out without peeling. They are strong now but I am still careful to not use my nails as "tools" so that I don't break them. I still have a split on my thumbnail but I believe it will grow out as long as I am careful and keep applying the product every few days. I will say my nails are a little "ridged" and I don't know if that's just my nails or a result of the product, but it is a small price to pay for strong nails and I can just buff them down smooth. The photos you see are: 1. at the beginning of use, 2. after 6 weeks of using the product, and 3. at 2 1/2 months (they do grow longer but I like to keep them short) Don't hesitate! Buy this product!
Review: IMPROVE YOUR NAILS IN FIVE MINUTES A DAY - I've been using it once a day for five minutes. I've only been following this routine for 4 days, but my nails are becoming shiny and strong. I apply it to my entire nail including the cuticle and let it sit five minutes. Rub it in, then spread all over my fingers and hands. It sells nice, but mild, must be the almond oil. Previously, my nails were chipping, splitting, dry and had severe ridges. They are now much smoother and strong and shiny. I love it! And i love my nails!

**Q: How long do I need to use Si-Nails for?**
A: Results can be seen in as little as 14 days. However, it depends on the condition of your nails before starting Si-Nails nail strengthening treatment. The condition of your nails will improve with extended use.

**Q: The first time I used Si-Nails, I didn’t see any product come out. How do I start using it correctly?**
A: Before using Si-Nails for the first time, activate the click pen by pressing down on the click button at least 25 times, until the applicator is moistened. This will activate the flow and you will be able to start using Si-Nails.

### ⭐⭐⭐⭐ Fantastic product!! Worked wonders for me!
*by S***8 on August 13, 2025*

This product has made such a big difference in my nails. My doctor sent me to a dermatologist who told me there wasn’t anything they could do for me since prior treatments were not effective. My nails had major ridges, the nail had separated from a portion of the nail bed, they would break or tear easily, and were thin. I started using this product on May 9, 2025, and I used it as recommended faithfully, and within weeks I was noticing such great improvement in my nails. They are stronger, have less ridges, and the nail is no longer separated from the nail bed. I thought it was ridiculous that I had to pay the $50 copay to the dermatologist only for him to look at my nails and discuss the situation for like 5-10 minutes. But since he recommended I try this product, and it has been successful in repairing my nails, I suppose the $50 copay was worth it in the end. 😆 I highly recommend this product if you suffer from similar symptoms. I’m including two “before” pictures, and one “after” picture. Great product!! The only reason I did not give 5 stars is due to the price, which I feel is a tad high. I was lucky to find it on sale, so I snagged two pens at the sale price.
