1. Scientists once created cheese made from armpit bacteria.
In 2013, scientist Christina Agapakis and scent expert Sissel Tolaas gathered microbes from body parts of volunteer artists, scientists, anthropologists, and cheesemakers. Bacteria from armpits, a foot, a bellybutton, and tears and were taken using sterile cotton swabs and processed into cheese. (source: The Daily Mail)
2. Polymastia is a condition wherein a person has more than two breasts, and the extra breast is usually found in the armpit area.
This shouldn’t be confused with polythelia, the presence of extra nipples. (source: Medscape)
3. You lose up to 38% of underarm skin every time you shave.
Can you just imagine how rough shaving can be on your kilikili?! That's a LOT of dead skin cells! (Source: Dove’s The Little White Book on Underarm Skin Care)
4. Yellow underarm stains on your white shirt aren’t caused by sweat, but by your apocrine glands.
They're larger and contain proteins and fatty acids that make underarm secretions thick and milky. These glands are located on the underarms, groin, and breast area, and are most often associated with body odor.
5. Armpit fetishism exists, but note that there's a huge difference between a real sexual fetish and just an admiration for smooth kilikilis.
As defined by the Kinsey Institute, “fetish” specifically refers to a strong sexual preoccupation with an object, material, or body part. Your boyfriend following @pinay_kilikili on Instagram may not be a sign of an armpit fetish—unless he starts begging to ram your underarms with his member.
6. Armpits have millions of microscopic animals living on every square inch of human skin.
The National Geographic likens our armpits to lush rain forests brimming with diversity. But there’s no need to freak out. Many of the microbes are healthy bacteria that keep our skin in good condition.
7. The left armpits of left-handed men smell "more masculine" than their right armpits.
A 2009 study wanted to see if the increased use of the dominant arm/hand would result in a "more intense" odor in the armpit region. Turns out, it's true!
