What Could It Be Mean To Be Covered In Cellulite?

My daughter is 10, one of twins. she is not very tall and has a very slim figure, but she is starting to get little rolls of flab round her belly and all her stomache is now covered in cellulite.she is starting to sweat under her arms so was unsure if it the start of puberty. please advice would be great, is cellulite right at her age?

thankyou Leanne
