Ridged nails, uneven surface, chipping polish… While common, these little imperfections can turn your manicure into a real headache! Luckily, you have an ally to save the day: the smoothing base coat. What does it do? When and how should you use it? We tell you everything about this superhero that always comes to the rescue of our nails!
Key takeaways:
- A smoothing base (or nail ridge filler) is a treatment polish that evens out the nail surface, just like a primer in makeup.
- It is ideal for ridged or uneven nails — ridges being an aesthetic concern, not a sign of a weakened nail.
- It serves two purposes: correcting imperfections (smooth surface, radiance even without color) and prepping for application (better adhesion and polish wear time).
- At Manucurist, it's Active™ Smooth, to be incorporated into a 2-week treatment routine (Basic, Starter, or Ultimate).
What is a smoothing base?
A smoothing base (or nail ridge filler) is a treatment polish formulated to even out the surface of the nails. It works just like a makeup primer: invisible yet essential for a flawless finish, ideal for ridged or very uneven nails.
A solution for ridged or uneven nails
Ridges are fine, visible lines on the surface of the nail. Whether vertical or horizontal, they often appear with age, but can also be amplified by vitamin and nutrient deficiencies, mechanical stress (excessive filing, overly frequent false nails or gel polish, and harsh removal) or health issues. All of these factors can disrupt keratin production, leading to ridges over time.
The result? Nails look dull, uneven, sometimes jagged at the free edge… However, this does not mean that ridged nails are weakened. Ridges are primarily an aesthetic concern. A tailored manicure routine with a smoothing base coat is all you need to visually blur these surface imperfections. That’s something to smile about!
Nail ridges: no need to make a fuss!
What is its role in a manicure routine?
The smoothing base is like a magic wand that guarantees an impeccable result, worthy of a professional manicure, right from home. It has two main functions:
- Imperfection corrector: it fills in ridges and creates a smooth surface for a cleaner finish. Even without colored nail polish, the nail appears brighter, cleaner and more even.
- Primer before applying nail polish: just like a Base Coat, the smoothing base acts as an undercoat that makes application easier, optimizes polish adhesion, extends wear time, and prevents smudging and premature chipping.
When and how to use a smoothing base?
The smoothing base easily fits into a complete nail care routine. It is applied directly to well-prepped bare nails.
Active™ Smooth: the ridged nail's BFF
For a flawless manicure, with or without color, we created Active™ Smooth, a treatment polish with a CC polish effect that acts as a smoothing base. It deeply nourishes and revitalizes the nail thanks to the regenerating properties of castor fibers, hexanal, AHAs and vitamin E in its formula. Its lightly tinted formula comes in 4 shades (rosé, beige, doré and bronze) that subtly complement different skin tones.
💡Tip: discover nail layering by combining Active™ Smooth with other care polishes from the Active™ range to switch up effects while continuously strengthening your nails.
