I go through many phases with loving red lips and there's no better time than Christmas. I bought the Revlon Colorstay Moisture Stain in Shanghai Sizzle whilst I was over in the States as I mainly wear stains. Sidenote: Unfortunately and very oddly, it looks like they don't do that shade here. I just really like the fact that once the colour starts to wear away the pigment that the stains your lips is still there.
I would say that Shanghai was a typical, bright, postbox red shade.The applicator is really soft and the formula is really pigmented and smooth. I do enjoy the high-gloss finish that gives to the lips.
Now for the bit that I don't like. I don't believe that this is stain lip product. I haven't found that if I was to put it on the skin leave it for a few minutes and then wipe away it doesn't mean any sort of the stain. Overall though I like the finish I wouldn't repurchase it for another shade because it doesn't do what I thought it would.
