OPI Repair Mode Bond Building Nail Serum | Keratin Protein Nail Strengthening Treatment | For Stronger Nails & Nail Growth

This serum really strengthened my nails and helped reduce peeling and breakage within a week. I love how lightweight it feels, and it absorbs quickly without leaving any residue. The ingredient list is short and effective, which I appreciate: • Alcohol Denat. – helps deliver the formula and evaporates quickly for fast drying. • Water (Aqua) – hydrates and helps blend ingredients. • Maleic Acid – bonds and fortifies the nail structure for strength & repair. • 1,6-Hexanediamine – supports nail surface bonding and resilience. Great for damaged, weak, or post-acrylic nails. I highly recommend this if you’re looking to rebuild nail strength without harsh ingredients. 💅✨

I’m constantly caught in a cycle of wanting long, salon-perfect nails and needing to leave them bare to recover from the damage. After a particularly rough manicure left my nail beds thin and sensitive, I decided to try the OPI Repair Mode Bond Building Nail Serum. I’ve always trusted OPI, but this is different from their usual strengtheners - it’s a liquid serum rather than a thick polish. What blew me away was the zero dry time. I can brush it onto my bare nails and by the time I finish the second hand, the first is already completely dry and absorbed. There’s no tacky film or shine, so I don't have to put my day on hold while it sets. It uses Ulti-Plex technology to actually repair the keratin from the inside, and I really felt that difference. I followed the 'intensive' instructions, applying it twice a day for six days, and my nails felt significantly sturdier and less 'bendy.' I’ve now repurchased this three times because it’s my go-to 'reset' button between salon visits. If you’re struggling with peeling or post-gel brittleness, this is a total game-changer for getting your natural nails back to a healthy, growable length.

I bought this as I was desperate to try anything. I have one little nail that refuses to grow in strong and keeps splitting down the center, vertically. I have kept it super short to try and not have it ripped off. I had polish on all the time. It took longer than advertised, more like 3-4 weeks to see results but it works. My nails are coming in stronger, less ridges, and that one nail is NOT splitting. Put it on twice a day with no polish or hardener or anything. Dries very fast. Really helps, I've seen a difference.

I would recommend this hands down. It’s a wonderful product. It has helped me grow my nails back out healthy and helped in the process of giving them strength while is in the in between stages.

Ok let's face it. I was totally skeptical that this would repair nail damage. I mean come on. How many times have we purchased something, only for it to wind up in the trash and the money down the drain. THIS STUFF WORKS!!! I damaged one of my nail bed with years of acrylic, gel and nail "Dip powders" pretty severly. Half of the nail grew at a normal rate and the other half did not. It also had a vertical crack that would not quit, and caught on everything. It was very painful. I had given up. I have been using this for about a month at this point. The nail is growing at a more normal rate. The overall split is virtually gone. I do still have a small divot in the tip of the nail, but it is no longer an actual split in the nail. Just a spot that grows a little slower. I had 2 other nails that were beginning to grow unevenly and they are fixed. I am a daily user of this product. No, I do not know what will happen if I stop using it. I don't think I want to find out.

Do not buy if your nails are severely damaged from gel/acrylics or are naturally thin. I thought I did my research, but it was until this damaged my nails more that I found out more about the product. The salon drilled all my gel off which thinned my nails severely. I didn’t think this would fill in those missing areas but I WAS hoping it would help with the keratin bonds and build strength with the nail I had left and any new growth. I used the product as directed, twice a day (about 12 hours apart) for 6 days. After I stopped using it, I noticed my finger nails felt like they were burning. I then noticed that the nail was separating from the nail bed. In the picture, my nails were already filed down as short as I could, down to the hyponychium. You can see that my “new free edge” is way below where it should be. This seemed to have happened because since the nails are so thin, the solution soaks into the nail bed (skin), which it’s not made for. The reaction of the chemicals/ingredients with the skin causes the separation. This is meant more for healthy layered nails that may have minimal peeling or other issues. But the nail should ideally have most of its layers so that to solution is only penetrating nail.. There should really be more information about this from OPI… I wanted to save my nails and made them worse.

I’ve been dealing with splitting, flaking, and brittle nails for a while. Trying everything including this product and after a month of daily use, I’m not impressed. It hasn’t changed the fact that my nails are still breaking, splitting, and flaking. I’ve gotten better protection just wearing a layer of good quality nail polish.

Purchased this in conjunction with OPI Nail repair and together, they restored my natural nails after they were destroyed by gel manicures. This product won’t fix your nails overnight but with regular use you’ll be amazed at how effective it is.

Le unghie mi si sono sempre spezzate sulla parte “rosa” un dolore cane e mai avute più lunghe di un millimetro . Il prodotto funziona! Le sostiene, le ripara. E quando l’unghia si spezza ( perché ovviamente non fa miracoli e quindi le mie unghie si spezzano comunque) si spezzano solo sulla parte “eccedente” la rottura si blocca e non va oltre. Non ci avrei mai creduto ma una bella svolta.

Compré este producto la semana pasada porque después de la última retirada de semipermanente que me hice noté que mis uñas naturales estaban súper frágiles y dañadas, hasta el punto de que me dolía horriblemente a la hora de hacer cualquier cosa con ellas. Me hago yo misma la manicura en casa y hace poco probé a usar unas uñas postizas, ha sido lo peor que he podido hacer en este mundo... después de quitarme las postizas, el pegamento me dejó las uñas horribles y me dolían mucho, así que probé a usar builder gel para protegerlas y ya no me dolían. Cuando pensé que me habían crecido lo retiré completamente y seguían mis pobres uñas naturales fatal. He probado bastantes productos que dicen endurecer o mejorar la uñas natural pero ninguno igual a este. Con la primera capa que me puse pude notar la diferencia... mis uñas pasaron de estar súper débiles y que dolían solo con verlas a poder tocarlas y sentirlas más fuertes. Solo con el primer uso me sorprendió porque ahora podía limar mis uñas naturales sin llorar del dolor. Ahora llevo ya usándolo durante los 6 días que promete que hace efecto, siguiendo las instrucciones de ponerlo 2 veces al día y sin duda mis uñas están maravillosas y más fuertes que nunca. Súper bueno el producto, es el mejor en el mercado ahora mismo y por lo que tengo entendido OPI tiene la patente, así que es el único en el sector con esta forma reparadora. Por lo que he podido leer, el producto actua en tu uñas creando más uniones entre las células con keratina y vitaminas. De esta manera se incrusta en tu uña, no es solo una capa protectora que se pone encima y hace de escudo, este producto penetra en tu uña y la hace más fuerte en su composición natural. Increíble!! Además, es súper fácil de usar y de poner, es un pincel súper fino que ayuda a llegar a todos los rincones y se seca rápidamente, en menos de un minuto ya está seco y puedes seguir con tu vida normal. No es nada pegajoso ni nada, es perfecto y da un resultado maravilloso!! Por lo que tengo entendido puedes ponértelo como primer antes de la base para la manicura semi y seguirá teniendo efecto. También he visto que puedes aplicarlo en tu uña a medida que va creciendo como si fuera aceite de cutícula para que la nueva uña que crece esté fuerte!! Es lo mejor del mundo y lo recomiendo 100%!!!

Si me funciona y a mi hija también! Es costoso pero vale cada peso, puedo traer las uñas desnudas y hacer cosas en la casa y sin maltratarse antes no podía tenerlas descubiertas ni un día sin que se partieran o abrieran en capas, mis uñas eran frágiles y delgadas ahora están súper sanas :) Si tienen dudas no lo piensen ! Nadie me pagó! Jajaja solo que ningún endurecedor del mercado o métodos caseros me habían ayudado .
