Tap to play or pause GIF Tap to play or pause GIF FOX / Via giphy.com According to the NHS, KP affects up to 1 in 3 people in the UK, and it's not a reflection of your general health – it regularly affects people who are otherwise completely healthy. 2. And it's more likely to affect you if you're young, female, and fair-skinned.

While it's not contagious, KP is hereditary.

It's just ~one of those things~. 5. It typically appears during childhood, and gets worse during puberty – but it also gets better during adulthood, and often disappears completely. Tap to play or pause GIF Tap to play or pause GIF NBC / Via giphy.com Yup, as if puberty wasn't bad enough, the condition affects 50-80% of adolescents. It's also at its least common among the elderly. 6. It's caused by some pretty darn science-y stuff... Tap to play or pause GIF Tap to play or pause GIF ABC / Via pbsdigitalstudios.tumblr.com According to the NHS, the condition is the result of an excessive build-up of keratin (a protein found in hair follicles) in the outer layer of your skin. The excess keratin blocks the hair follicles and, in turn, causes your skin's pores to grow in size and become rough and bumpy. 7. While it's most likely to affect the skin on your upper arms and thighs, in rarer cases it can be found on your forearms and upper back.

It's often more prevalent during winter, because of the colder, less humid weather. Tap to play or pause GIF Tap to play or pause GIF Disney / Via giphy.com KP is essentially a variant of very, very dry skin (which is why it's so common in people with eczema), so the cold, dry air during winter tends to make it worse. 10. It can't be completely cured (sorry!), but there are several measures that you can take to improve the appearance of your KP. View this photo on Instagram instagram.com There's no need to go to a dermatologist to treat your KP – there's no way to cure it completely, so that would pretty much be a waste of your time. However, there are things you can do, according to the NHS, that will improve the condition. It's recommended that you regularly use a gentle exfoliator, use moisturisers that contain salicylic or lactic acid, and use non-soap cleansers instead of regular soap on the affected area. 11. The most important thing to know is that you shouldn't feel insecure about it. Not only do a lot of people have KP, it's also highly likely that it will go away as you get older.
