I attribute my regular intake of cod liver oil to my not burning last summer. I tanned nicely, when I usually burn then go back to white. (And I mean, *white*!) We haven't been taking it as regularly, and got burned on the first sunny day we were out a lot. I've attempted to up our intake considerably. I should also start with the regular applications of SJW oil again. I started in March last year, and it totally slipped by me this year!
