1-3 days after applying the polish there was relatively little wear on the nail varnish which I found amazing because normally without a top coat you can begin to see slight chipping and just overall wear on the nails in this time frame.
4 days after applying the polish I developed a small amount of chipping on corners of the nails, but this was not extremely noticeable to anyone else apart from me, and it was not bad enough to have to reapply the whole nail varnish layer on your nails. But in the same respect, if you were particularly bothered by this small amount of chipping you can easily reapply 1 or 2 coats of nail polish on top to hide this, but personally it was not bad enough for me to do this yet.
So far I have been particularly amazed by the long lasting finish of this polish especially without applying a top coat, suggesting that if you did it would last for much much longer than without. I will continue to update this throughout the remainder of the week to see how this continues to progress, but so far I have been extremely impressed.
