I bought one of these due to the hype. My colour was a gorgeous pink colour (Marilyn I believe it was called). I tried this on my lips the minute I got home as I was too excited to try. First impression was that the colour on the lips is nowhere near what I expected it to be...I found it to be quite dull. I am not a huge gloss person, and again, I expected it to be more of a liquid lipstick than a sheer gloss, so I was disappointed. Though for someone who is in love with hi-gloss shine, it would be a must.
In terms of longevity, it most definitely did last as well as it said, so I was very impressed with this. I guess it was a bit on the sticky side, but from experience, no stick, no last!
The stain aspect was quite nice, just a nice subtle pinch of colour. But again, I felt like the hi-gloss did not suit me so much so the stain was a bit lost. I did end up wiping the gloss off to see what the result would be with the colour, and again, the stain was definitely not a disappointment.
So to conclude, this did not really suit my needs (my bad for not researching more into them), however I would recommend to any friend after a nice sheer-ish gloss/stain. I did end up passing my colour onto my mother who seems to be enjoying it so far!
I own both Yves Saint Lauren Glossy Stain (in #10) and 2 shades of the caresse (berry persistent and light pink). I believe this is the best dupe of YSL. - The packaging is not really my favourite, the golden part gets old pretty quickly. + The lipstain texture is quite hydrating during the first 2 hours using. However, it may dry out later and you need to apply another layer or lip balm (this is the only drawback comparing to the YSL stain) + The shades are really amazing, pigmented and staying quite long (up to 4-5 hours). . Even when it starts to fade, it still leaves this beautiful post-shade which is quite natural. Moreover, it gives a little gloss on your lips without being sticky like lip gloss + I also like the affordable price of this L'oreal lipstick line. I bought mine off ebay for only 12$ each - One small turn-off for me is the smell, it is just like chemicals to me.
