Review: saved my nails!!! - back when i bought this, i had just used press ons and they ripped the whole top layer of my nail off and left other nails torn to my nail bed. i was devastated and since i work with quite a few chemicals at work, i was in so much pain. i knew i couldnt go back to press ons to protect them, nor could i use polish, so i turned to oils. this was a first choice and now, about 2 months after using whenever i remembered to, my nails are fully healed and actually so much stronger than before. they took a while to grow out but this product helped so much. in addition, i used another nail oil that specialized in strength and the combination worked wonders. i used to have paper thin nails and now my nails can actually withstand things!! thank you for saving my nails <3 ( also maybe its just me but while using this product and nail honey ((the other oil i used)) i didnt cut my cuticles at all!! and please dont trim them, they protect the area between your skin and nail. you are prone to infections if you practically scoop the out everytime you do your nails. think about it, do you ever sanitize your nail polish applicator? and when you get your nails done by someone else, they use that same polish on other people... 🤨)

**Q: This has parabens in it!??**
A: The packaging does not list parabens as an ingredient.

**Q: Can I use this over my nail Polish?**
A: You need to read the pkg instructions as with any new product.  I wear it on bare nails only and under any polishing I use polish.  I believe the instructions also suggest the underside of your grown out nail.  You should always read all instructions before proceeding with any product.
