I have seen this type of lip gloss around (the type that go on clear and turn the perfect pink for you) but until now never bothered to try one. I got this half off and though why not?
The lip gloss itself is very nice, a slightly thick formula that is not too sticky and stays on for a relatively long time. The colour changes depending on you, but it basically works by slightly stinging your lips so they get pinker. If you have really red lips it will probably just look like clear gloss, but if you have pale lips or brownish lips it brings out the pink tones very nicely.
