Manucurist SOIN Keratine Booster 15ml

A concentrated nail treatment serum for brittle, thin or peeling nails. Keratine Booster combines essential amino acids, peptides and botanical extracts to stimulate repair and fortify the nail plate, helping nails become stronger and less prone to breaking or splitting.

Who it’s best for

Ideal if:

• your nails are fragile, prone to peeling or breakage;

• you often wear polish, gel or semi-permanent and want to strengthen nails between manicures;

• you’re looking for a focused treatment to reinforce nail structure and prevent damage;

• you prefer a more natural, vegan-friendly formula.

Key benefits

• Strengthens the nail plate, reducing fragility and breaking.

• Helps rebuild nail integrity, reducing peeling and splitting.

• Lightweight texture, easy to apply — can be used as a base under polish or as a standalone treatment.

• Contains amino acids and peptides supporting healthy nail structure and growth.

• Suitable either as a treatment between manicures or as a protective base before polish.

Why it works

• Amino acids and peptides penetrate the nail plate and support rebuilding of natural keratin, strengthening the structure.

• Restoration of protein structure makes nails more flexible, less prone to cracking or splitting.

• With regular use, nails gradually regenerate and become more resilient to repeated manicures.

How to use

1. Clean and degrease nails thoroughly.

2. Apply a thin layer of Keratine Booster on each nail.

3. Let it dry completely.

4. Use either as a base under polish or as a stand-alone treatment on bare nails.

5. For optimal results, apply 2–3 times per week until nails feel noticeably stronger.

Expected results*

• Nails become stronger, less brittle and less prone to splitting.

• Nail structure is reinforced, with a healthier, more uniform look.

• Fewer breaks and splits, more confidence in nail length and easier polish application.
