Keratin Booster is an intensive serum treatment. It absorbs into the nail plate instantly. Use it daily and see real strength return within three to four weeks. Apply with the brush, working from the free edge to the cuticle. Repeat several times a day for best results. The fast absorbing formula leaves zero residue. It suits every nail type, even severely damaged or brittle nails. Hydrolyzed Keratin replenishes the nail's own protein. Panthenol and Allantoin restore hydration and elasticity, so nails bend instead of breaking. Biotin and Hydrolyzed Silk deliver a smoother, stronger nail.

Good To Know

How do I apply Keratin Booster?
Apply the serum to the nail plate using the built-in brush, pushing from the free edge towards the cuticle so the formula reaches the full nail surface. It absorbs instantly. Use it several times a day on clean nails.

How long does it take for Keratin Booster to work?
The serum absorbs instantly, so there is no drying time. For visible improvement in strength and less breakage, use it daily over three to four weeks. The more often you apply it each day, the faster the result.

What is the difference between Keratin Booster and Nail Hardener?
Keratin Booster is a serum that absorbs into the nail plate and works from within, replenishing keratin and restoring elasticity with daily use. Nail Hardener is a coating that reinforces the surface and can also be a base coat under polish. For severely damaged nails, the Keratin Booster is the more intensive option, and both can be used together.

Why do nails split, and how does keratin help?
Splitting is usually caused by dryness and a loss of elasticity, so the nail breaks instead of bending. Hydrolyzed Keratin replenishes the protein the nail is made of, while Panthenol and Allantoin restore hydration and elasticity, addressing the root cause rather than just coating the surface.
