did not work for my thin nails [SEP] i have yet to find a nail polish or nail polish base coat top coat combination that actually works on my nails maybe it is just me because my nails seem to be thinner and more flexible than lots of peoples but no matter what polish i wear it always chips within a day this base coat did not extend the life of my manicure any more than polish alone perhaps it is a coincidence but my nails also took longer to recover after i removed this product they usually get flaky at the tips after i wear nail polish but after using this base coat my nails continued to flake for over a month i only wore it once
