Well if you want to get rid of the freckles for ever then you could get a dermotologist to do IPL, they would fade a lot and if you had it done enough they would pretty much disappear for good.
However if you don't like the idea then that EL foundation is the worst thing you could put on your dry skin - it's like armour plating and pretty hard and unflattering. How about trying a BB cream (one of the Korean ones, like Skin79 or Holika Holika - you can get them on Ebay and they aren't expensive). Way more moisturising and they offer really very good coverage. You'll probably look 5 yrs younger too.
Otherwise go with a light coverage hydrating foundation (have a browse on Makeupalley for reviews, it's fantastic) which won't cover the freckles, but then go over the freckles with a liquid concealer and a tiny brush. it sounds like a hassle but with a bit of practice it won't take long, and it's a much softer look. Check out Lisa Eldridge's site for info/ideas/video. I've learned loads from watching her. Try experimenting with some of the cheaper brands like MUA and Borjois, you might be pleasantly surprised.
