Fading freckles? help please!?

hey there, I have quite a lot of freckles on my face which I'm happy with, they don't seem to bother me, but last summer I was badly burnt on my chest and shoulders, from falling asleep in the sun without sunscreen, (I know, stupid me:/) but I was badly blistered/burnt, since then I've developed loads and loads of freckles on my shoulders, which I wouldn't really care about either, but there's a strap mark on either shoulder, where you can see my once smooth, pale coloured skin.

it looks quite stupid if I'm honest, and the same with the ones on my chest,

I'm only 15, so it makes mr quite self conscious on holiday etc:/. and I'm sick of the 'omg; you have so many freckles' line.

is there a way I could lighten my skin with a product? To even it out.. I was thinking about a fake tan to make my freckles look less obvious, but that would cost to keep doing, :/.

and I cant afford surgery either,

any home remedies? I heard about lemon juice an sour milk, but I'm not sure, if there are any products that could help I'd be so grateful!

Thankyou, :) xxx
