for me.. well, i love both lipstick and lipgloss, it depends on the look I want to achieve.. I usually go for lipsticks (matte and creamy.. love them) when I want to look more natural, and gloss for when I feel special :P
Lol, I have quite a lot of favourites.. I feel bad if i try one and dont like it :) My favourite glosses are, in fact, care-glosses.. I really, really like Superbalm Moisturizing Gloss from Clinique, have 4 of them and.. want more :P and I purely love High Colour Gloss from estee lauder.. i love the shape, the ease of application and my favourite colour for a gloss, Quartz.. :P And now I have a huuuuge crush for Stila's lip glazes. They recently came to Romania and wanted to try all! No matter how dark they seem to be, when you put them on the lips they look like a fresh, lovely hint of colour.. Apricot, Vanilla, Grapefruit and Strawberry are what I own right now. Little quantity for the price, but they're totally worth it :P
I also love dearly Silk Gloss from Max Factor, Hi-Shine Lip treatment (body shop), creme des levres from bourjois (i know i wrote a review also:P) and the beauty balm in chocolate bunny from too faced! aww, that's simply delicious..
But really, my all-time favourite gloss is Shiny licious, from Maybelline. Beats Juicy Tubes anytime, anywhere. They're just awesome, sheer and juicy, suitable for any occasion or look.. Of course they dont last long, but I feel the need of re-applying lipgloss anyway, so that's something that never bothered me.. I only care about the way it looks on my lips. So if it's light and.. sorbet-like, I love it. I only hate those lipglosses that look like glue, and feel heavy on the lips.. like Collistar.
My favourite lipstick now is L'Oreal, Accord naturels, in Nude. It is so creamy, so gorgeous, exactly my shade of nude. I also love love love and adore Rouge Interdit, from Givenchy. It's the best texture and best product I've ever tried for my lips until now, and I have the Only Beige shade. It is pricey, indeed, and the shade is really nice, a little lighter than my natural lips, so l'Oreal can be a good substitute.
And sooooorry for being so long :)
