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: It Works! Nail Health Improved Almost Immediately - I wish I had thought to take "before" pics for this review. For years, my nails have been an embarrassment. The nails were brittle and would just rip apart if they grew past my nail bed. The top layer would peal back. If I was out with a group of people I would try to keep my fingers hidden. Sometimes, I notice women looking at them. Ugh, what an embarrassment. I finally went to a dermatologist who ran some tests. Results... my body is no longer storing "zinc", which promotes strong nails and hair growth. She immediately recommended this product. After using one pen, you can see in the pics that my nails look pretty healthy and are growing again. I'm so relieved that I just needed to write this review. If you are experiencing these types of issues with your nails, see your doctor, but also, give this product a try! ## Features - YOUR SOLUTION FOR: brittle or weak nails - TESTED: Increases nail strength and durability while helping to repair brittle nails and reduce roughness - TECHNOLOGY: Silanediol salicylate promotes silicon, one of the predominant minerals in the nail, while pistacia lentiscus gum promotes keratin, an essential component to strong and healthy nails.

It should always be applied directly to bare nails that are clean and dry. **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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing results! *by L***F on June 4, 2024* This stuff was literally an answer to prayer!

Actually a bit of a rip off given the price of the product. I have used a similar product with supposedly the same amount of product in the pen and it has lasted me more the twice the mount of time. Another issue ... you cannot see what is in the pen. So, imagine my surprise when I could no longer "click" the pen and pressing the top did not do anything at all. Pen was dried up. Does not matter if it works as it won't last long enough to make that determination. I frequently spend large amounts of money for top of the line cosmetics ... if they deliver what they promise ... I am fortunate enough to be able to buy more. This is not a product I will repurchase nor will I recommend it to anyone. I don't mind spending money ... but I really dislike being cheated. ## Frequently Bought Together - ISDIN Si-Nails - Fast Absorbing Nail Strengthening and Hardening Serum for Nail Durability in Thin Nails, made with Cationic Hyaluronic Acid 0.08 FL OZ - Onyx Professional Hard as Hoof Nail Strengthening Cream with Coconut Scent, Nail Growth & Conditioning Cuticle Cream Stops Splits, Chips, Cracks & Strengthens Nails, 1 oz - OPI Repair Mode Bond Building Nail Serum | Keratin Protein Nail Strengthening Treatment | For Stronger Nails & Nail Growth --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/145823493-si-nails-strengthening-and-hardening-nail-serum-treatment-0-08](https://www.desertcart.sn/products/145823493-si-nails-strengthening-and-hardening-nail-serum-treatment-0-08) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-24*
