Albinism is a rare genetic disorder that causes a lack of pigmentation in the skin, eyes and/or hair, giving albino people a unique look:

It’s very rare to have an albino child… which makes it remarkable that one Kazakh couple had not one, but two albino children 12 years apart.

Asel is the older sibling at 14. Her mother, Aiman Sarkitova, said she was stunned when she was born albino.

“When I gave birth to my eldest, genetics were not so developed with us,” she told the Daily Mail. “It is developing only now. The doctors were shocked.”

Imagine their surprise when, 12 years later, Kamila was born with the same condition.

It’s an incredible, striking sight to see these two siblings together—so the two teamed up and became a modeling duo.

Asel has already been modeling since she was 10, but with her 2-year-old sister at her side she’s become even more in-demand. The pair have over 33,000 followers on Instagram.

While their albinism has led to big success, it’s not always easy. The condition is also associated with medical conditions like a sensitivity to sunlight.

“If I go outside in the afternoon, then I definitely apply sunscreen, put on clothes to protect my skin, headgear or use an umbrella,” Asel said.

“In the evening, when there is almost no sun, it’s much easier for me.”

But through whatever ups and downs life throws at them, they’ll always have each other.

The condition is so rare that albino people can feel alone, but these two sisters are lucky that they’ll always have a family member just like them.

And hopefully, their success as models will shed some light on albinism and show how uniquely beautiful albino people can be.

“Many people do not know what albinos are,” Asel said.
