Manucurist Keratine Booster Nail Strengthener — Clear plant-based serum for stronger, smoother nails

Manucurist Keratine Booster is a lightweight, plant-based nail serum that immediately strengthens and refines the look of soft or damaged-looking nails.

Built for everyday use, this clear nail care serum combines plant-based keratin, biotin, silicon, AHA, gluconolactone and vitamin C in a formula that absorbs quickly to leave a dry-touch glossy finish without greasy residue. With 97.5% ingredients of natural origin and a cosmetic-focused approach, it helps improve surface texture and visual density while fitting easily into a routine before or between polishes.

How quickly will I see improvements in nail texture?

Visible smoothing and a more even nail surface can appear within days of regular application, while measurable strengthening is best seen after a short course. The serum is designed for repeated daily use to build cumulative benefits and improve overall appearance.

• Apply 1–3 times daily to bare nails for immediate smoothing.
• Recommended short course: 5–7 days for noticeable surface improvement.
• Use more frequently for added glossy finish and visual density.

What ingredients make this a strengthening nail treatment?

The formula relies on plant-derived keratin and biotin to support the nail plate’s visible structure, while silicon, AHA and gluconolactone help refine texture. Vitamin C contributes an ingredient often used for cosmetic brightening and overall polish to the appearance.

• Plant-based keratin and biotin for visible density and resilience.
• Silicon plus AHA and gluconolactone for surface refinement and smoothness.
• 97.5% natural origin ingredients, cosmetic-grade formulation.

How do I use the Keratine Booster for best results?

Brush onto clean, bare nails and allow the serum to dry—no rinsing required. It can be applied up to three times a day during a treatment phase and should be used for several consecutive days for clearer visible benefits.

• Apply with the included brush to bare nails, 1–3 times daily.
• Let dry completely before touching or applying polish; no rinse needed.
• Use for 5–7 days as a focused routine; cleanse before polishing for optimal adhesion.

Will this work with nail polish and regular manicures?

Yes—this clear serum is formulated to sit comfortably under polish or be used alone for a neat glossy look. For best polish adhesion, clean the nail surface before applying color; the product’s dry-touch finish prevents buildup between layers.

• Use as a base treatment before polish for healthier-looking nails.
• Leaves a natural glossy finish if worn alone—no greasy feel.
• Clean nails before polish to ensure optimal color bonding.
