Nail polish removal

In the past I usually just grab any local nail polish removal in local supermarket, until last week, I just I give it a go for this stuff. First I thought that any removal will give the same effect as its base is just aseton. My nails will usually become yellowish after wiping it out and become blur. But when applying this product, I become amazed (too exagerating? ;) ), since my nail is not become yellowish, and less blur compared with the 'local unbrand' one.
