INGREDIENTS

Increased AHAs & PHAs

AHA/PHA stands for alpha hydroxy acid/Poly hydroxy acid. They help promote cell turnover and restructure and strengthen damaged nails. They can also help nail structure to become denser and aid moisture absorption.

Glycerin

Glycerin acts as a nail hardener to help strengthen the nail. It also has moisturising benefits and increases the water content in the nail.

Biotin

Biotin also called B7 is part of the family of B vitamins. Biotin has been shown to improve nail strength and length and can help with splitting and breaking.

Panthenol

Panthenol also known as Pro-Vitamin B5 works as a humectant, pulling moisture into the nail plate to aid flexibility and growth. It is able to penetrate through the nail to provide moisture whilst softening and protecting.

Hexanal

Hexanal promotes the growth of strong, healthy nails, increases flexibility and promotes rapid healing of the natural nail.
