Key Ingredients Protein Formula 4 for Nails, Strengthen 15ml

• 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.
