The OPI Repair Mode Bond Building Nail Serum is designed to strengthen and repair dry, brittle nails. One of its main strengths is the high concentration of nail keratin repair, boasting 99% repair when used as directed. This makes it particularly effective for those suffering from significant nail damage. Users can also expect up to 94% protection from further damage and nails that are up to four times stronger within six days of use.

The serum contains keratin protein, which is essential for nail strength and growth, making it a suitable choice for anyone aiming to improve the health of their nails. Additionally, the vegan formula and the cap made from post-consumer recycled materials highlight the brand’s commitment to sustainability and ethical practices, which can be a significant plus for eco-conscious consumers.

However, the product comes in a relatively small volume of 0.3 fluid ounces, which might not last long, especially if used frequently as directed. It's also important to note that individual results can vary, and some users might not see the same level of improvement. The application method is straightforward since it comes in a liquid form, and it is easy to incorporate into daily routines. This product seems most beneficial for those with dry, brittle nails looking for a vegan, protein-based treatment that promises quick results.
