Starter Routine - Ridged Nails

Good product

I bought this because I have ridged nails, especially on my thumbs - which probably are because of age + not looking after them well. I have used this dilligently (per instructions) for 2 weeks now and can see visible difference. My nails look and feel a lot smoother. The ridges are still there but noticeably smoother.

Not what I was expecting and no instructions on how to use it as some say needs to go on clean nails nightly and the ridge varnish not sure how long this to be on and if you can use other products at same time

Works on my ridged nails
