Which ingredient is often found in nail strengtheners?

The presence of formaldehyde in nail strengtheners is linked to its ability to effectively bond and reinforce the keratin structure of nails. This ingredient can help increase the durability of the nail while providing a hard protective layer, which can be particularly beneficial for those with soft or brittle nails. Formaldehyde’s cross-linking properties give it strength, making it a common choice in formulations designed to enhance nail health and withstand breakage.

While other ingredients like calcium carbonate can contribute to nail care in various formulations, they do not have the same structural reinforcement properties that formaldehyde provides when it comes to improving strength and resilience. Acetone is primarily a solvent used for removing nail polish and does not contribute to strengthening nails. Titanium dioxide is typically used as a pigment and does not play a role in enhancing nail durability or strength.
