From the set of Mad Men to the runways everybody is seeing red. Hollywood starlets such as Cameron Diaz and Jennifer Morison sport crimson lips on the red carpets of the Golden Globe Awards.  Dior’s Spring 2010 show at New York Fashion Week paraded scarlet lips as part of a very 1940s Hollywood glamour look down the runway.

Urban Decay's lipstick in Revolution is a great strong red with very slight blue undertones. For more of a subtle hint of firey color try Julie Hewett's Oona.  It's a very sheer sexy cherry red stain whichgoes on smooth.

Medium skinned: Go for a bright fire-engine red like Penelope Cruz.

Illamasqua's lipstick in Encounter is rich with pigments.  The super intense formula is sure to help you make a statement in red.

Have red hair: You can still wear red lipsticks but look for warm undertones.  Try a tomato or brick shade.

Jouer's lipstick in Peggy is a great bronzed red with flecks of gold.  It's a perfect red that wont leave you looking as if you matched your hair to your makeup.

A little scared of reds:

For a sheer red which radiates confidence try Three Custom Color's Bette.  It's a creamy lipstick which as they say is "Like a power suit.. for your lips."

Still unsure which red is for you? DuWop's Private Red morphs to your perfect color.  It's made from three natural pigments derived from annatto, hibiscus, and henna.  Just apply the silky color to your lips and within five minutes you're wearing your perfect shade.  It's like the mood lipsticks of the 70s only instead of telling if your happy or sad they make your lips look smoking hot.

Expert tip for wearing red lipstick: 

For a perfect pout like Scarlet Johanson’s try using DuWops Reverse Lip Liner.  It's a clear matte pencil which helps prevent your lipstick from sweeping out into those little ines around your mouth.  Johanson's makeup artist swears by it calling it a little fence for your lips.  The stuff really works.  It's rumored that even Queen Elizabeth is a fan.
