Synonyms for the word "frecked" could include "spotted," "dappled," "speckled," or "flecked." Other options might include "mottled," "freckled," or even "sprinkled." Regardless of the term used, all refer to the same physical characteristic, and it's a testament to the rich diversity of language that we have so many words to describe something as simple as freckles on a person's skin.
