Specifically formulated for weakened nails, the Manucurist Kertain Booster works to deliver strengthening, smoothing, and protective benefits.

Its biomimetic formula combines plant-based keratin, silicon, and biotin to visibly densify and harden, while AHA and gluconolactone gently exfoliate the nail plate for healthy growth. Complete with vitamin C, an antioxidant, the blend helps to protect your beds against any external stressors.

The lightweight, fluid texture absorbs quickly, infusing fast, targeted care without a greasy or sticky finish, leaving fragile nails visibly nourished and revitalised.

Apply 1 to 3 times a day on bare nails. Repeat daily for 5 to 7 days.
