Eczema Treatment Care

She’s 2 yrs old and I sue Eucerin cream and over the counter hydro cortisone for her spots of eczema. Her legs look dry, splotchy and dirty all the time, even after a long bath with lots of scrubbing followed by creams. Her legs are much worse in the summer, because she wears shorts and the skin is exposed to plants that sometimes worsen the eczema. Any ideas of what may help?
use Eucerin cream- sorry
