I know I'm really late on the new YSL product because I'm having finals and have to wait till now to do a review of it.
It retails for S$40 if i remember correctly. The colour that i bought was #2 which is a soft yellow tone pink. The colour is really lovely but I do wish that I've got it in #9 instead because i was contemplating between #2 and #9 which is a nude. Although on the 2nd thought I should have gotten it in brighter colours because brighter colours look flattering when it is matte.
I love it much more as blush than lipstick because this pink do look a bit too pale of a pink on my lips but a perfect doll pink for my cheeks.
It can be applied lightly or layered to a full opaque lipstick. It is matte but not drying but not recommended to be applied on top of chapped or dry lips.
Longevity wise , it wasn't as long lasting as I expect it to be although it blends seamlessly into my cheeks when applied. It would only last about 4 hours where as my Chanel cream blush lasted the entire day 8-10hrs and you still will be able to see a little bit of pink even at the 12 hr mark.
I would not repurchase this product in this colour again, however I might get #9 for the nude that i'm always on a hunt or the brighter colours to see if brighter colour will last longer.
