Shellac was in development and testing for over five years before it was released.
The ingredients in it are safe, they don’t soak into your nails. The molecules sit right on top of the nail so it’s not entering into the bloodstream and it’s not touching your skin, so this is safe.

As far as the safety of the UV light that is definitely a legitimate concern. I actually have two clients that have previously had skin cancer so this was a concern that was brought up and I’m happy to address it.
The amount of UV light that you are exposed to while getting your Shellac nails done is about the same as 20 seconds of actual sunlight, or walking to your car every day. It’s a very minimal amount of light that you’re being exposed to. The UVB rays or the more harmful rays are filtered out in the CND lights so that shouldn’t be a concern.
If you’re still concerned about the light you can either put sunblock on your hands or put a towel over them so that the rays are not penetrating the skin.
I hope this helps, if you have questions feel free to post comments below and I’ll give as much information as I can!
