You may want to change your source. I have to limit tanning to once every 10 or more days and try to be infrequent about pinning because I, chronic type I complexion, have gotten too dark.
As my wife put it, you're all dressed up and no where to go. Wee took pictures the other night and what I thought was just a slight base color was still really dark. So once I get closer to competition time I will increase dose and tanning frequency again. Point is try a different sources first. It may not be you r especially if it has worked for you in the past.
