I love it!!
I haven't been using it for long yet, but after first application, I'm impressed! It definitely looks and feels like it's doing something, which I can't say for some base coats. It also seems to smooth the nail. I think it helped to make my nails look juicy and plump.

Great Nail Armor :muscle::skin-tone-3: (Mind the pup🫣) This is after 2 coats of Base Fortifante. I usually go for 2-3 coats. Im very busy with my hands and my nails have a tendency to flake in layers and chip. This is the second time I've used this product and it helps seals the nails' layers for about 1-1. 5 weeks. I've noticed less chipping and flaking and my nail edge has been able to grow out nicely without worry of damaging them.
Game changer
