Swirls of yellow paste made from ground tree bark decorate the cheeks of Rohingya Muslim women and girls in the refugee camps of southern Bangladesh. Thanaka, a type of sun protection that dates back centuries, is a common sight on the faces of the women, who say the use of the traditional cooling paste helps bring a sense of normality to their difficult lives in the camps. “The make-up is my hobby, and it's our tradition”, said Juhara Begum, 13, who arrived in Cox's Bazar in September last year after fleeing a military attack on her village in Myanmar's Rakhine state. “The military fired guns and slaughtered us”, said Juhara, who had to walk for five days to reach the border. Now, she lives on a hilltop in the crowded refugee camp of Jamtoli. “I live on top of the hill and it is too hot with the strong sun”, said Juhara, who wore the protective paste on her face.
