Very effective on natural polishes.
My nails seem healthier after using this polish remover compared to acetone ones. The scent is herbal and a bit strong at first but dissipates quickly. I like to hold the remover on the nail for 30 secs or so before I start rubbing off the polish; it seems to work best that way. I took off one star because of the scent and the small bottle size. I would purchase it again.
