So, I love the melted matte formula AND the original melted formula--they're my favorite lip products on the market. There are quite a few differences between all of the Melted Matte's that I have tried.
I have owned and/or tried Child Star, Feelin' Myself, Sell Out, Queen B, On Point, Candy Cane, Lady Balls, and Drop Dead Red.
In general the dark colors (On Point, Drop Dead Red) are more easily removed and don't necessarily stay put all day (they can be removed with a tissue and water). The lighter shades (Child Star, Sell Out, Queen B) actually have great staying power and even last through meals (not too greasy). The bright colors (Candy Cane, Feelin' Myself, Lady Balls) transfer more than the others.
On Point is a dark plum/red/brown that is easily removed. It can be applied sheer or opaque. I have very fair skin with a cool undertone, and it wasn't the most flattering shade on me. This looked beautiful on my mother-in-law who has tan skin with a warm undertone--she sheered it out and it looked great (it is difficult to wear sheered if you have any texture on your lips--exfoliate first!). My sister in law with fair skin and a warm undertone tried this and it looked nice and vampy when applied opaquely.
Child Star is a great nude for fair skin and leans more brown. It has great staying power.
Sell Out is my personal favorite and looks great on my fair skin. It is truly my lips but better (a touch darker). It looks great with my cool undertone. This one also lasts through meals.
Queen B looks great on my sister-in-law (fair skin, warm undertone). I wear it also but it pulls more purple-toned on me (more natural on her).
Feelin' Myself is BRIGHT. It is not a dusty coral... it is a bright coral/melon. It's definitely bold on my fair skin and I like wearing it with the Sweet Peach palette.
Candy Cane is a beautiful reddish pink. It tastes amazing and I often find myself snacking on my lipstick throughout the day. It has a nice cooling sensation due to the peppermint. It does seem to transfer more than any other (I get it on my fingers, but it isn't noticeably missing from my lips). The color does seem to last on my lips a while, even with my constant licking it... This looks good on my fair skin (cool undertone) and my sister-in-law (fair skin, warm undertone), although it was too bright for her taste. (Definitely not a neutral).
Lady Balls is a great red that looks very classic and whitens the teeth.
Drop Dead Red is probably my least favorite... if applied opaquely it is quite vampy. If sheered out, it looks very purple... much more purple than red, which just wasn't the look I was going for... I expected it to be more Burgundy than plum.
They're all great and definitely worth investing in. I think I will try Cool Girl next... I've always eyed Unicorn... but not sure I can pull that one off...
