There may be a huge sexual benefit to back dimples

Dimples: Chances are, if you don't have them, you want them.

Looking at the celebrities smiles of Miranda Kerr and Jennifer Garner, dimples seem to be a facial feature many wish they inherited. We've even heard stories of people using makeup or biting the insides of their mouths in hopes of achieving the popular look.

Dimples can be described as natural facial indentations -- some scientists attribute dimples to the
"shorter muscles near the cheeks," according to Bright Hub. Others believe it's due to variations in the "Zygomaticus major muscle."

But some people want dimples so badly that they are willing to go under the knife for it. "Dimpleplasties" have been on the rise for years, and involve plastic surgeons taking "chunks" from the insides of their patient's cheeks.

As facial dimple surgeries continue to rise, so do dimple surgeries on the lower back. A sign of a "healthy" body, "Venus dimples" sit right at the base of the spine. And just like facial dimples, people are flocking to the plastic surgeon to replicate the indentations of Kendall Jenner and other models.

Dimples on the lower back don't just mean you're healthy, but they are also "indicators of good health and a screaming sex-life," according to The Sun. The publication explained that dimples help "facilitate good circulation," and thus make it easier for women to orgasm.

Dr. Amanda Wong-Powell, from London, explained the aesthetic reason behind the surgery. "The lower back has always been championed as a beautiful region of the female body. However, with the rise of aesthetic surgery of the buttocks, many people are realizing that lifted buttocks only look good if paired with a sexy sculpted lower back – one fails to look good without the other," she said to The Sun.

But surgery to replicate the diamond-shaped indents come at a hefty price -- beginning at £4,900 (over $6300). Ouch!
