A fan-favorite amongst beauty buffs, OPI Nail Envy will give you longer, healthier nails your friends will certainly swoon over. The clear lacquer can be used on its own or as a base coat to prevent polish from weakening or drying out your nails. If your fingertips really need some TLC, it’s buildable and recommended to add a coat once a day for a week to get ’em back into shape. The secret to its protective powers lies in its formula, which is enriched with hydrolyzed wheat protein and calcium your nails will appreciate (and admirers will covet).

What reviews say: “Lots of polish out there that claiming to strengthen—THIS ONE DOES! Get yours for troubled nails, you will be thrilled,” — Amazon customer

No time for a professional manicure? No problem—ISDIN’s nail treatment pen takes all of one minute to use and can be applied anywhere, thanks to its click ‘n go design.

For the best results, apply it once a day for 1-2 weeks, making sure you get everything from the cuticle to even underneath the nail (yes, really). That felt tip makes application super simple and dries in a flash, which is particularly helpful when you’re on a time crunch.

What reviews say: “It works much better than treatment lacquers that eventually have to be removed and usually make nails look worse afterwards thanks to the products used to remove them. I have far less splitting and peeling and my severe nail ridges look smoother from this product. My only problem is getting used to using hands that now have fingernails after a lifetime of them barely having anything growing beyond the nail plate,” —ISDIN customer

Want a powerful polish with a bit of tint? Essie’s got you covered. Instead of using it every day, you only have to use it once: Simply apply two coats to clean, dry nails, let them dry, and go.

It doubles as a glossy clear coat, too, and is tinted with juuust a touch of color (in pink or violet) to give your nails a healthy looking glow.

What reviews say: “I’ve been using this for a few months now and it’s my go-to nail treatment/polish. It gives such a nice shine and a VERY subtle pink tone to your nails. I’m pretty hard on my nails, so they break a lot. I’ve never had long nails before, so I bought this to finally get nice nails, haha. The polish does peel off pretty easily for me. But again, I’m hard on my nails! The good thing is that you can reapply it and it looks like new. Definitely recommend!” — Ulta customer
