What is the Purpose of a Base Coat?

5 min to read
Before diving into a whirlwind of colours, there's one simple yet essential step you must not forget: the base coat. The true foundation of your manicure, it protects the nail, strengthens it, and extends the wear of your polish. But which one should you choose? For what purpose? And why is it so essential? We’re here to give you all the details you need to achieve the perfect manicure and radiant nails!

 

A base coat is the base of it all

The base coat is the first essential step in a successful manicure. Applied to bare nails before polish, it is usually transparent. Just like a makeup primer, a base coat evens out the surface and preps the nail for colour application. But its role doesn’t stop there… it’s much more than just a corrector!

Protection, adhesion, and long-lasting wear

Applied before polish, the base coat creates a smooth surface that helps polish adhere and extends its longevity. It also acts as a protective barrier between the nail and coloured polish, preventing pigments from staining your nails and shielding them from external factors (like humidity) that could weaken them.

Before or after polish?

At Manucurist, both the Green™ and Green Flash™ manicure routines follow a simple 4-step rule:

  • 1 layer of base coat
  • 2 thin coats of polish
  • 1 layer of top coat to seal the colour and extend wear

⚠️ Don't confuse base coat with top coat!

While the top coat is the final step, adding shine and ensuring a perfect finish, the base coat is the very first layer before applying polish. Thanks to it, you get a smooth surface for seamless polish application. Another benefit: it prevents pigments from adhering directly to the nail plate, making colour removal much easier with a gentle, acetone-free remover.

Which base coat for which polish?

First and foremost, it's crucial to use products from the same range, as their formulas are designed to work in harmony.

The type of base coat you choose depends on the polish you’re using:

  • If you're using Green Flash™ gel polish, the Green Flash™ Vitamin-Enriched Base Coat is the one for you. And here’s some fabulous news—it now features a brand-new formula combining hexanal, vitamin C, and vitamin E for the first time! Thanks to these active ingredients, it strengthens nails from the very first manicure and enhances the wear of your gel polish for up to 12 days! Application remains the same: apply a thin layer and cure under an LED lamp. Let’s flash ⚡️

Depending on your nail type, it’s important to choose the base coat that suits you best. Our nail diagnosis tool will help you find the perfect match for your needs.

After just one week of use, breakage and splitting are reduced, keratin production is stimulated, and the overall condition of your nails is visibly improved.
