OPI Repair Mode Bond-Building Nail Serum — Keratin Strengthening Treatment, Vegan PCR Cap, Daily Use

OPI Repair Mode is a bond-building nail serum that penetrates the nail to rebuild keratin bonds for visibly stronger, smoother nails.

This lightweight serum uses OPI's patented Ulti-Plex Technology™ to reach beneath the nail surface and help reconstruct internal keratin structure. The formula is designed for daily use to improve nail resilience, reduce the appearance of ridges and discoloration, and help protect against everyday damage from washing, cleaning, and cosmetic services. It’s formulated without animal-derived ingredients and comes with a cap made from post-consumer recycled (PCR) material.

How quickly will I see results with Repair Mode?

Many users notice cosmetic improvement after the first application, such as increased shine and smoother surface texture. Continued daily application supports structural repair so nails become noticeably stronger over days to weeks.

• Visible smoothing often after one use
• Stronger nails within about a week when used as directed
• Progressive improvement with ongoing daily use

How does the serum actually rebuild nail structure?

The product employs Ulti-Plex Technology™ to penetrate the nail plate and form new internal bonds within keratin fibers rather than only coating the surface. That internal support helps reduce splitting and breakage while improving plate integrity.

• Penetrates the nail rather than sitting on top
• Targets keratin fibers to recreate internal bonds
• Complements protective routines like gloves during chores

Can I use Repair Mode with polish, gels, or acrylics?

Yes — Repair Mode can be used beneath polish or between services to support nail health. Apply to clean, dry nails as part of your prep or after removing enhancements, following any recommended wait times for products you layer over it.

• Works under nail polish as a base step
• Suitable for use between gel or acrylic services
• Apply to bare nails for maximum repair benefit

Is this serum safe for sensitive users and cruelty-free routines?

The formula is vegan, containing no animal-derived ingredients or by-products, and the product packaging includes a PCR cap. As with any concentrated treatment, perform a patch test if you have highly sensitive skin or nail conditions.

• Vegan formula — no animal-derived ingredients
• Packaging includes a cap made from recycled materials
• Recommended patch test for very sensitive users
