Kératine Booster 15 ml

The Manucurist Kératine Booster is an intensive strengthening treatment for soft, thin, and damaged nails that need greater strength and resilience. The highly concentrated, biomimetic formula with a plant-based keratin complex, silicon, biotin, AHA, and vitamin C absorbs into the bare nail within a few seconds - without leaving a greasy film or a polish layer.

• Intensive nail treatment for soft, weakened, and damaged nails
• Supports strength, resilience, and nail structure
• With plant-based keratin complex, silicon, and biotin
• AHA & gluconolactone support a smoother nail surface
• With vitamin C and amino acids as complementary care ingredients
• Liquid texture absorbs quickly - non-greasy and non-sticky
• 96.5% ingredients of natural origin
• As an intensive 5-7-day treatment, 1-3 times daily

Unlike a strengthening base coat, the Kératine Booster does not remain on the nail as a polish layer. The fluid texture is applied directly to the untreated nail and absorbs completely. This makes it particularly suitable for periods when soft or damaged nails need targeted strengthening - for example, between two manicures or after heavy stress.

For an intensive treatment, use the booster daily. You can then apply polish as usual; simply degrease the nail surface thoroughly beforehand.

Benefits & Care

The Kératine Booster combines structure-supporting ingredients with gently smoothing acids and is particularly suitable when nails appear soft, thin, split, or stressed by frequent manicures.

• Plant-based keratin complex: Hydrolyzed chickpea extract, together with quinoa and lentil extracts, provides plant-based protein building blocks and complements the keratin-like care formula. They support nails that look stronger and more resilient.
• Silicon: Complements the strengthening formula and supports the structure and strength of the nail plate.
• Biotin (vitamin B8): Specifically used in care for soft and brittle nails, it complements the formula to support strength and resilience.
• AHA & gluconolactone: Glycolic acid and gluconolactone support gentle smoothing of the nail surface and help rough or uneven-looking nails appear more even.
• Acetyl Cysteine: This sulfur-containing amino acid complements the formula with a building block that structurally complements the keratin-rich nail plate.
• Vitamin C: Magnesium ascorbyl phosphate complements the care formula with antioxidant properties and supports protection of the nail surface.
• Apricot kernel oil: Provides the nail with additional nourishing lipids without making the fast-absorbing texture feel heavy or oily.

The current formula consists of 96.5% ingredients of natural origin according to ISO 16128.

Kératine Booster, Base S.O.S., or Huile Verte?

The three products serve different purposes:

• Kératine Booster: intensive, absorbent treatment for soft and damaged nails that specifically need greater strength.
• Base S.O.S.: film-forming base coat and treatment for brittle, splitting, and significantly stressed nails - it can also be worn as a base coat under Green™.
• Huile Verte: lipid-rich daily care for dry nails and cuticles when softness and replenishment are the main priorities.

For particularly stressed nails, the Kératine Booster also combines well with the S.O.S Overnight Nail Mask: booster during the day, mask as intensive overnight care.

How to use

• Apply the Kératine Booster only to clean, unpolished nails.
• Using the brush, apply a thin layer over the entire nail plate 1-3 times daily.
• Allow to dry for a few seconds until the liquid texture has absorbed completely.
• Do not rinse off or massage in.
• Repeat the application daily for 5-7 days.
• For very soft or heavily stressed nails, the booster can be used as an intensive treatment 3 times daily for 7 days.
• Take a break between several treatments and monitor the condition of your nails.
• If applying nail polish afterward, thoroughly degrease the nail surface beforehand so that the base coat and polish adhere optimally.
• Suitable from age 12.

FAQ

What nails is the Kératine Booster suitable for?
It is particularly suitable for soft, thin, damaged, or splitting-prone nails that lack strength and resilience.

Is the Kératine Booster a nail hardener?
It is an intensive strengthening nail treatment, but not a classic film-forming nail hardener. The liquid formula absorbs completely into the natural nail and leaves no polish layer.

What is the difference compared with Base S.O.S.?
The Kératine Booster is used as a time-limited intensive treatment that is absorbed directly by the nail. Base S.O.S., on the other hand, remains on the nail as a protective polish layer and can also be used as a base coat under Green™ color polish.

How quickly does the booster absorb?
The alcohol-based texture absorbs within a few seconds and leaves neither a greasy nor a sticky finish.

How long should I use the treatment?
Daily for around 5-7 days. For very soft or severely damaged nails, the booster can be used three times daily for seven days.

Can I use the Kératine Booster several times a year?
Yes. However, there should be a break between individual treatments.

Can I apply nail polish afterward?
Yes. Once the booster has fully absorbed, you can apply polish again. Thoroughly degrease the nail plate beforehand.

Can I use the Kératine Booster under Green™ or Green Flash™?
Yes, but not as a replacement for the respective base coat. Once the booster has absorbed, thoroughly degrease the nail surface and then use the respective manicure system as directed.
