I am 58 and yes, I remember adding iodine to the baby oil to tan. I also remember hospitals smelling of iodine.
I used sesame oil and iodine for tanning this summer with great results.
I am 60 years old and layed out this past Saturday using Johnson's Baby Oil and Iodine. I did it frequently when I was young. I may lay out only 4 or 5 times a Summer now. I had to order the Tincture of Iodine off the internet for about $5 a bottle. The drug stores don't carry it any more. I am olive skinned so I mix it strongly. One bottle (about an ounce)in a regular bottle of Johnson's Baby Oil. ( Johnson's Baby Oil is the best!)Shake the bottle well and frequently as the iodine sinks to the bottom and separates. I put on liberally (even in my hair). I try to lay out for about an hour and a half turning as needed. It gives your skin a yellowish brown color (very nice!)I recommend it but it has no sun screen in it so be careful not to over do it!
