It can be difficult to tell regular siblings apart, let alone twins. However, these two sisters have shared a sure-fire way to spot the difference between them
Many notice a family resemblance with their relatives – but these twins take their similarities to the next level.
Sisters Vitoria and Alessandra Campo, who live in Australia, have the same brunette locks, chiselled cheekbones and toned figures. At first glance, it could even be difficult to spot the difference between them.
However, there is a subtle difference that only becomes apparent in the sun. That’s because one of the twins tans a lot more than the other!
In the clip, both twins lay their heads down in the sand, with the camera only capturing them from the neck up. They then simultaneously turn their heads to look directly at the camera.
Overlaying the footage, the sister added text which reads: “POV [point of view]: you’re twins but one stole all the melanin in the womb.”
Melanin is the natural pigment in the skin responsible for the colour of our skin, hair and eyes.
It’s produced by cells known as melanocytes, which also protect cells from harmful UV radiation by absorbing it. The production of melanin increases with sun exposure, resulting in some people’s skin tanning and becoming much darker than others.
There are two types of melanin; eumelanin, which produces darker colours such as brown and black, and pheomelanin, which is responsible for reddish and yellowish tones, typically found in red hair and freckles.
Even though twins – especially identical twins – share the same genetic makeup, there are several reasons why one twin might get more tanned than the other.
External factors can play a role. For example, how long each of the twins spends out in the sun and what their lifestyles are like.
However, genetics can also come into things. Even identical twins can have tiny genetic or epigenetic differences that affect how their skin produces melanin (the pigment responsible for tanning).
And according to Vitoria and Alessandra, this is what has happened in their case!
