I currently have one of these glossy lip stains and have mega plans to purchase them alllll!
I really really love the one I own and have been wearing it alot lately. I have shade 15 which is a beautiful pink colour.
I cannot believe how these stay on your lips! It amazes me how long the glossy shine actually lasts - even through eating and drinking. The colour stays on forever, even once a bit of the shine has worn off.
I find this really comfortable to wear as well, it is light on the lips and while it does have a very slight tackiness, it is not overly sticky and annoying.
The packaging is to die for, so luxurious and pretty. I also love the applicator, it is the perfect shape for applying the product evenly all over the lips.
This is definitely a pricey purchase, but I really think it is worth it. As I already said, I wear the one I have all the time so to me it is totally justified! :p
I adore this product. It goes on like a dream, and stays on for hours. I love the packaging, square and fabulous. It doesn't roll around in my makeup drawer. Rather expensive at $55 but I have not found any other product that matches it's performance. Great colour choice available. YSL always looks like quality and luxury. The only downside is getting my hands on it as I live in a provincial centre and it is not sold nearby.
Tips: Follow their guideline and wait a few minutes after the first coat before putting the second and final coat on.
