This is the sole product I can genuinely depend on to revive my weak, damaged nails.

      If there's one aspect of my beauty routine that I'm truly passionate about, it's maintaining healthy nails. Having previously indulged in consecutive gel manicures, I frequently found myself searching online for ways to strengthen my nails. I was also continuously seeking nail strengtheners, cuticle oils, and other products to rejuvenate them. After trying some of the best products available and consulting experts on effective nail care, I found one product that I rely on above all else: a nail serum.

      What Is a Nail Serum? So, what exactly is this product? According to expert manicurist Faye Louise Dennis, "Consider a nail serum as a treatment in your skincare routine, specifically formulated for the nail plate and cuticles. Unlike products that merely coat the surface, a quality serum is designed to penetrate the nail and work from the inside out."

      What Are the Benefits of a Nail Serum? "Using a nail serum regularly can reduce issues like dryness, peeling, and breakage, while also promoting healthier-looking nails over time," explains Rebecca Crawforth, founder of the renowned nail brand Navy. If you're curious whether this product could aid weak or damaged nails, the answer is a definite yes. However, it’s essential to recognize that it isn't an instant solution. "Though a serum won’t repair damage immediately, consistent use can enhance flexibility and minimize further breakage as the nails grow," Crawforth adds.

      How Often to Apply a Nail Serum With that in mind, you might be wondering how often you should apply a nail serum for optimal results. Dennis suggests applying it twice a day, if possible. "It may seem like a lot, but once it becomes a routine, it only takes seconds, and the improvement is noticeable," she notes. "The key to maintaining that salon-fresh look between appointments is consistency in your nail care."

      Sound appealing? I certainly think so! Below, you'll find my personally tested selection of the top nail serums, alongside expert suggestions. You’re welcome...

      **The Best Nail Serums, Tried & Tested**

      **Best Nail Serum Overall:** OPI Repair Mode Bond Building Nail Treatment Serum, £30

      **Best Nail Serum On-the-Go:** Margaret Dabbs Nourish Nail and Cuticle Serum Pen, £13

      **Best Expert-Approved Nail Serum:** Bio Sculpture Ethos Golden Nail Serum, £16

      **Best Luxury Nail Serum:** Dior Huile Abricot, £30

      1. **OPI Repair Mode Bond Building Nail Treatment Serum**

       **Best overall**

       How to use: Apply to bare nails twice daily for six days; thereafter, use it as a base under your favorite polish.

       Pros: Effectively strengthens nails, works quickly.

       Cons: Higher price point, must keep nails bare for the first week.

       The team at Who What Wear UK considers OPI Repair Mode one of the top nail serums available. In fact, beauty editor Eleanor Vousden noted that her nails stopped breaking once she started using it. "I’m completely sold on this nail growth serum," she states. "At £30, it's one of the priciest serums I’ve tried, but trust me, it truly works." How does it work, you wonder? It employs the brand's Patented Ulti-Plex Technology to penetrate the nail's surface and form new bonds, thereby leading to stronger, smoother nails. The only drawback? You have to apply it to bare nails twice a day for the first six days, but after that, it can be used beneath your preferred polish.

      2. **Margaret Dabbs Nourish Nail and Cuticle Serum Pen**

       **Best for on-the-go**

       How to use: Apply a thin layer twice daily.

       Pros: More affordable than other options included here, convenient for on-the-go application.

       Cons: Strong scent, thicker consistency compared to others.

       Margaret Dabbs London has a strong reputation in nail care, and this serum is no exception. Available in a handy, pen-like format, this hydrating formula contains tea tree oil (giving it a robust scent) to nourish dry nails and prevent infection. While the serum is somewhat thicker than others I've tried, it absorbs quickly and imparts a lovely shine to the nails while providing nourishment over time.

      3. **Bio Sculpture Ethos Golden Nail Serum**

       **Best expert-approved serum**

       How to use: Use the pipette to apply to cuticles.

       Pros: Expert-approved, supports nail health.

       Cons: Contains shimmer, which may not appeal to everyone.

       Dennis highly recommends this Bio Sculpture serum, stating, "It makes my nails look radiant while genuinely enhancing their health from within." This formulation penetrates deep into the nail structure to address dryness at the source, rather than just sealing in moisture. Featuring green tea for antioxidant protection and biotin for stronger nails, it absorbs neatly without any stickiness,
