White freckles, scientifically called leucoderma gutata, are small white spots on the skin, between 1 and 10 mm in size, which are usually caused by excessive exposure to the sun. UV rays damage melanocytes, which are the skin cells that produce melanin, a substance that gives the skin a darker color.
The most common places for these white spots are the arms, legs, back and face, and appear mainly in people over the age of 40.

Diagnosis of white freckles can only be made by the dermatologist by looking at skin lesions.
The most important step in the prevention and treatment of white freckles is to wear daily sunscreen on sun-exposed skin, with a minimum protection factor of 15. The ideal way to go to the beach is to invest in sunscreen with a higher protection rate, ideally spf 50, and avoid the hottest hours, between 10am and 4pm.
Além disso, deve-se ainda consultar um dermatologista, que pode indicar um tratamento que pode ser feito com uso de tretinoína tópica, com laser, dermabrasão ou criocirurgia com nitrogênio líquido. Estas técnicas ajudam a remover a camada superficial da pele, promovendo a regeneração da pele sem manchas.
