a powerhouse nail and cuticle serum for ultimate repair + recovery
We guarantee that your Peptide Serum Concentrate is filled to the intended 10 mL — and even a little more! The extra room at the top helps the dropper dispense properly and prevents pressure build-up, so no product is lost to leaking.
Pull the cap straight up, tilt the bottle, and aim the pointed tip at your cuticle. Gently press the soft base on the bottom of the bottle to release one drop per nail, then massage in.
A supercharged dose of cuticle care proven to target dryness, brittleness, and damage.
Formulated like a potent vitamin shot with 12% active ingredients—our highest concentration ever—this lightweight gel-serum delivers 360° support that helps strengthen, moisturize, and renew in one drop. Use for total nail rejuvenation and repair: it’s cooling on contact to soothe stressed cuticles, then quickly absorbs to fortify nails from the base and encourage healthier regrowth.

non- greasy and absorbs quickly. It remains to be seen whether it works or not. I will know better some months from now as my nails grow out.
I use this Exceptional product 2 ways; daily on cuticles and weekly as part of my manicure. My nails are stronger, better textured and are growing longer. YAY.
It is very moisturizing and I do enjoy really enjoy the way it smells. I like the product and feel it works well in terms of that. I'm still testing it. That being said.....
A big con though is the application. This product is expensive so not being able to control well how much comes out is wasteful. Also, just opening it up you have to be careful not to push the bottom or the serum will come out, same with closing it.
We’re so glad you’re enjoying the moisturizing feel and scent so far! We also really appreciate your feedback about the application and the difficulty controlling how much serum is dispensed. That’s an important part of the overall experience, especially with a concentrated formula where a little goes a long way. Our Customer Service team will reach out directly to help make the application easier and ensure the rest of your experience with the serum is a positive one.
I'm almost 75, and my two thumb nails had lots of ridges in them. I decided to give this serum a try, and the results are tremendous! The first bottle almost left my nails completely healed, so I ordered two more to finish the job.
As I get older, my nails have gotten ridges and break easily.
This product might just help. I’ll let you know in a few more weeks.😉
