I apply it all over my face and neck before bedtime and wash it off in the morning. I just use a simple cotton pad to spread it over my face, this method works well for me.
I top up the tan on my face every 3 days and my body every 7 days.
For reference I'm nc15 in MAC which at times looks dark on me but with Xen-Tan i'm up to nc25.
Beware these photos are of my bare face which you shall all see is far from flawless.
Sorry I had to crop this one, I had two huge, horrible spots.
Hope this was what you were after happy1234 x
