Remember when your cool, older cousin warned you that shaving your legs too often would cause the hair to grow back thicker? Lies. Lies. LIES. We set out to debunk seven of the most common beauty myths.

beauty myths crossed legs

Myth: Sitting cross-legged will give you spider veins

Truth: Spider veins can be caused by prolonged sitting or standing, smoking and obesity. They’re also genetic. So you can blame any of those sources, but there’s no need to uncross your legs.

beauty myths shaving

Myth: Shaving makes hair grow back thicker

Truth: This one’s an old wives’ tale. Shaving doesn’t change the structure of the hair follicle, hence why some women are OK shaving their faces.

beauty myths pores1

Myth: You can shrink your pores

Truth: Unfortunately, pore size is genetically determined, and can’t be changed. You can, however, make your pores appear smaller than they are.

beauty myths gray

Myth: Plucking a gray hair will make two more grow back in its place

Truth: Pulling out one hair doesn’t affect the follicles that surround it, so more hairs won’t magically appear. You should, however, resist the urge to pluck at will--nobody wants a bald spot.

beauty myths oily

Myth: Only people with dry skin need to use moisturizer

Truth: It sounds counterintuitive, but it’s actually super important for people with oily skin to moisturize. When skin is deprived ofmoisture, say, like when you're trying to dry out a pimple, it overcompensates by producing even more oil. Neutrogena and Murad make great formulas for shine-prone faces.

beauty myths toothpaste

Myth: Toothpaste is an effective treatment for acne

Truth: Toothpaste does dry pimples out, thanks to ingredients like hydrogen peroxide, alcohol and baking soda. But in the long run, its other ingredients could cause irritation, redness and peeling.

beauty myths sunscreen

Myth: You don’t need to wear sunscreen when it’s cloudy

Truth: You’ve heard it a million and one times, but please wear sunscreen every single day, no exceptions. Even when the sun isn’t shining brightly (or at all), its rays can cause damage. According to the Skin Cancer Foundation, up to 80 percent of the sun's UV rays easily pass through clouds.
