It is too early to tell if it is working
Please hear me out: I have tried dozens of oils, serums, and brush-on treatments to keep my cuticles moisturized and to help repair my nails after wearing acrylics and gel manicures. Everything from coconut and olive oil at home to expensive products. I have paid a little and I have paid a lot. After decades of biting my nails, getting acrylic and gel manicures and biting off even those, I wasn’t sure I could grow my nails to even have the whites on top. I have been applying this treatment for 15 days and my cuticles are immaculate, my nails are growing out stronger, and my existing nail beds that were covered in gels and glue are smoother. I will be buying this for as long as it is made!!
As for the bottle not being “full” as some reviewers say, the bottle is glass and the product wouldn’t come out if there was no air space. After two full weeks of using it, the bottle is still more than half full.
*Note for the manufacturer: please put the literal application instructions on the box too. It took me forever to figure out that the bottom is to be pushed to release the product. I was trying to shake it out like ketchup. 😂
I love this product. My cuticles have never been better
see above
I am extremely happy with this product! It’s my nail spa before bed every night.💕 It has rejuvenated my dry cuticles and is a soothing finish to every day.
