White patches on skin

Saleena • Victoria Elizabeth Elliott 👶🏻💝 Audrina Everleigh Elliott 👑👶🏼

These patches started a few weekends ago only on the legs. They are spreading up her legs to buttocks back and arms now. They aren’t itchy they don’t get red or raised. Has anyone ever seen this?! Do you know if this will scar her skin? Any tips on what to do?
