Red lipstick is saturated with sexual connotations. Hardly surprising, given that its primary function is to make lips look like a female’s privates.

Crude, but apparently true. According to Diane Ackerman, author of A Natural History of the Senses, anthropologists believe that red lips serve as a reminder of the labia, which “flush red and swell when they’re aroused.” (Too much information?)

Ackerman also points out how, in more recent years, lips are almost always decorated in shades of pink or red and then topped off with a finishing layer of gloss “to make them look shiny and moist.” No need to clarify what Ackerman’s getting at there.

In which case, when you apply either red lipstick or lip gloss (and especially if you apply both) what you’re actually subconsciously trying to do is emulate your own physical state of sexual arousal. Goodness me.

So basically the purpose of wearing red lipstick and/or lipgloss is to increase sex appeal. Hard to deny that one. Take a look at the following pictures, and you’ll see that a strong element of each woman’s sexual allure is, indeed, a result of the bright lipstick she’s wearing.

Having said that, lipstick hasn’t always been used purely for sexual purposes. As mentioned in Yesterface’s post It’s all in the lips… the cultural significance of lipstick has varied over the centuries according to societal trends.
