Manucurist Keratin Clear Nail Care Serum — Clear Nail Strengthener with Plant Keratin & Biotin, Fast‑Dry Gloss (Transparent)

Manucurist Keratin Clear Nail Care Serum is a fast-absorbing, plant-based serum formulated to visibly strengthen and smooth soft or damaged-looking nails while leaving a natural glossy finish.

Designed for daily use, this transparent nail serum blends plant-derived keratin, biotin, vitamin C, silicon, AHA and gluconolactone into a lightweight, non-greasy texture that dries quickly. The formula is 97.5% natural origin (ISO 16128) and created to improve nail surface appearance without leaving residue, making it a practical step between manicures or as a polish-free treatment. Made in France by Manucurist, the product follows clean-beauty standards and supports eco-friendly, vegan, and cruelty-free values.

How does this serum improve the look of weak or damaged nails?

The serum works by delivering conditioning and structuring ingredients that smooth uneven ridges and give the nail plate a more compact, polished appearance. Repeated applications help the nail surface look denser and healthier without using colored polish or harsh hardeners.

• Plant-based keratin and biotin to support visible nail density
• Silicon and AHA for smoother, even surfaces
• Vitamin C for brightening the nail bed appearance
• Fast-dry texture eliminates sticky residue

How do I use Manucurist Keratin Clear Nail Care Serum in my routine?

Brush the clear serum onto clean, bare nails once to three times daily, allowing each coat to dry fully—no rinsing required. For best results, use the serum for 5–7 days as part of a short intensive cycle, then maintain with regular applications; remove oils before polish for better adhesion.

• Apply on clean nails with the included brush
• Let dry fully between coats; no rinse needed
• Use daily for 5–7 days for visible improvement
• Clean nails before polish for optimal hold

Will the serum feel heavy or leave build-up under polish?

No—the formulation is engineered to absorb quickly into the nail plate, creating a dry-touch finish rather than a tacky film. When applied as directed, it provides a clear glossy look without thick build-up and can be used beneath nail color once the surface is clean.

• Light, fluid texture absorbs instantly
• Leaves a neat, natural gloss without greasiness
• Suitable as a base under polish after cleansing
• Does not create visible layers or residue

What is in the formula and are there any clean-beauty credentials?

The serum contains 97.5% ingredients of natural origin (ISO 16128) and combines plant-based keratin with biotin, silicon, AHA, gluconolactone and vitamin C to enhance nail appearance. Manucurist produces the serum in France within a vegan, cruelty-free, and eco-conscious range free from many harmful substances commonly found in nail products.

• Plant-based keratin and biotin for structural support
• Silicon, AHA and gluconolactone for smoothing action
• Vitamin C for a brighter-looking nail surface
• Vegan, cruelty-free, and mostly natural formulation
