Yes argan oil can be used to tan with as it's fast drying and leaves a light weight dewy complexion on your skin.
You can also buy argan oil spray tan solution that you can spray on your skin at home and get a tan from the argan oil without need to be out in the sun to get a suntan.
Another good oil for getting a suntan with is baby oil.
Baby oil makes for a great safe tanning oil and it's good for your skin too.
The baby oil helps your skin draw in the sun and creates a faster tan than not using sun tan oil or baby oil.
After using baby oil on my skin when suntanning I find that I get a faster tan and a much better looking tan.
