Beauty Myths Debunked
"Wax rips the hair out at the follicles," explains Woolery-Lloyd. "And any repeated injury to the follicles over time―we're talking 20 years―could damage some follicles to the point that they don't grow back." So employ waxing for its ability to keep your legs smoother longer than shaving can, not for diminishing hair growth.
Myth 8: Preparation H deflates puffiness.
This is a secret of makeup artists everywhere, and there's a lot of anecdotal evidence to suggest that this hemorrhoid cream can reduce undereye baggage, but no clinical studies have been done. One of the product's ingredients, a yeast derivative that is said to reduce puffiness, is no longer found in the version that's available in the States. (The cream was reformulated in 1994.) The other ingredient that is credited with reducing inflammation is phenylephrine, which temporarily constricts blood vessels. Nevertheless, using Preparation H around the eyes can cause dry and inflamed skin, says McBurney, so use this only where it's meant to be used, south of the belt line.
