If I added up how much money I've spent on back-to-back gel manicures over the years, I'd probably be able to take myself on a five-star holiday for the same amount. What can I say, I love having my nails done. That said, I'm currently saving for a wedding, and my natural nails are definitely looking (and feeling) a bit weak and discoloured as of late, so in a bid to improve both my nails and my bank balance, I cancelled my next salon appointment and bought myself a nail brightener instead.

I hadn't tried one before, but after giving this product a go, I am completely hooked. My nails have never looked so elegant and put together from an at-home polish. In fact, I've cancelled all my nail appointments this autumn, and will only be using a nail brightener from here on out. Below, I've rounded up my current go-to formulas, and I even spoke with nail expert and brand founder Leighton Denny MBE to learn more about what makes a nail brightener so effective.

What Is a Nail Brightener?

There are lots of nail health products on the market, from nail hardeners to nail strengtheners, but nail brighteners are a little different. "I like to think of a nail brightener as like a BB cream for the nails," says Denny. "It enhances the natural nail rather than covering it up, helping to brighten and conceal minor imperfections while giving the nails a fresh, healthy-looking glow. It’s perfect if your nails are looking a little dull or discoloured, but it’s just as much about that 'your nails but better' look."

As explained by Denny, although these products are great for concealing minor imperfections, they work for anyone and everyone. "You don’t need to have a particular nail concern to wear one," he says. "If you like that clean, polished, barely-there manicure, this is for you. For me, it’s about enhancing the natural nail rather than masking it, leaving nails looking fresh, healthy and beautifully groomed."

How to Use a Nail Brightener

The best bit? These products couldn't be easier to use. "Apply one coat as a brightening base coat under your nail colour, or build with two to three coats worn alone for an illuminated nude look," says Denny. You don’t even need a top coat.

"It’s such an easy way to make natural nails look instantly fresher and more polished, whether you want just a hint of brightness or a little more colour," Denny adds.

1. Manucurist Active Bright

best overall

Manucurist Active Bright

Pros

  • Adds a brightening effect
  • Strengthens nails

Cons

  • Not widely available

This Manucurist polish is one of my holy grails. It instantly illuminates the nail with a subtle yet buildable pearlescent effect. Nails look brighter and healthier, and the formula contains lemon extract, AHAs and hexanal to strengthen and repair the natural nail. If you like a milky nail look, you will love this.

2. Leighton Denny Nail Illuminator

best do-it-all formula

LEIGHTON DENNY Nail Illuminator

Pros

  • All-in-one formula
  • Lasts a long time

Cons

  • Not everyone will love the milky shade (but there are more colours available)

Speaking of milky nails, this Leighton Denny Nail Illuminator is another favourite of mine. It comes in a stylish milky white hue and acts as a base coat, polish, nail brightener and nail treatment all in one. Similar to the polish above, it has a subtle shimmer and is packed with nourishing ingredients such as vitamin E and lime tree extract. Plus, it lasts a surprisingly long time on the nail.

3. Dior Nail Glow

best luxury option

Dior Nail Glow

Pros

  • Adds a subtle tint to the nails

Cons

  • More expensive

If I'm cancelling my nail appointment, I want my at-home manicure to feel just as luxurious, and this Dior polish always does the trick. Not only is it gorgeous to look at, but the formula adds an elegant tint to the nail, making them look brighter, shinier and more polished. It's the closest thing I've found to a salon-worthy manicure at home.

4. Nails Inc. Glow and Grow

best affordable option

Nails Inc. Glow and Grow Nail Growth Treatment

Pros

  • Strengthens the nail
  • Can be used alone or as a base coat

Cons

  • Struggling to think of any!

For just under £10, this Nails Inc product really impressed me. It adds such a glossy, bright effect to the nail and can be used as a base coat or on its own, depending on your desired finish. However, it's the formula that I really love, which works to strengthen and nourish the nail thanks to a blend of hyaluronic acid and castor oil.

5. Chanel Le Vernis La Base Camélia

best for nail health

CHANEL Le Vernis La Base Camélia

Pros

  • Smooths and adds a glossy finish
  • Coats the nail in a protective layer

Cons

  • More expensive

This Chanel nail polish is technically a base coat, but I love using it as an all-in-one product for a subtle yet sophisticated manicure. As soon as I apply it, my nails look smoother, brighter and glossier. Plus, the camellia oil coats the nail in a protective layer, so I know they are taken care of, too.

6. Manucurist Active Smooth

best salon-worthy finish

Manucurist Active Smooth

Pros

  • Blurs the natural nail

Cons

  • More smoothing than brightening

I know I've already talked about Manucurist, but the formulas are so good that I thought the Active Smooth polish deserved a place in this edit. It's not as brightening as Active Bright, but it's ideal for smoothing and blurring the nail, making everything look healthier and brighter overall. I like to think of this as a skin tint for your nails.
