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

      If there’s one aspect of my beauty routine that I’m truly enthusiastic about, it’s the well-being of my nails. Having previously indulged in consecutive gel manicures, I frequently found myself searching online for ways to strengthen my nails. Alongside that, I was consistently seeking out nail strengtheners, cuticle oils, and more to revive them. After trying several top-rated products available and consulting experts on effective nail care, I've discovered one item 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 akin to a skincare product, but specifically formulated for the nail plate and cuticles. Instead of merely sitting on the surface, a high-quality serum is intended to penetrate the nail and function from the inside out.”

      What Are the Benefits of a Nail Serum? “Using a nail serum regularly can help alleviate 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 about whether this product could benefit weak, damaged nails, the answer is a resounding yes. However, it’s important to recognize that it’s not an immediate solution. Crawforth adds, “Although a serum won't instantly mend damage, consistent use can enhance flexibility and minimize further breakage as the nail grows.”

      How Often to Apply a Nail Serum With that in mind, you might be wondering how frequently to apply a nail serum for optimal results. Dennis suggests applying it twice daily, if feasible. “It may sound like a lot, but once it becomes routine, it takes just seconds, and the difference is noticeable,” she notes. “The most important thing you can do between appointments is maintain consistency in your nail care. It keeps your nails looking salon-fresh for a longer period.” Interested? I thought so. Below, you’ll find my tried-and-true selection of the finest nail serums, along with some expert recommendations. You’re welcome...

Beauty editor Eleanor Vousden noted that her nails ceased breaking once she started using it. “I'm completely convinced by this nail growth serum,” she explains. “At £30, it’s one of the pricier serums I’ve tried, but believe me, it really delivers.” How, you ask? It features the brand's patented Ulti-Plex Technology, which penetrates the nail surface and forms new bonds, producing stronger, smoother nails. The only downside? It requires twice-daily application on bare nails for the first six days, but thereafter, you can use it beneath your favorite polish.
