: I have the exact same experience, right down to the number of days

: stays brown, the amount of time it stay s orange, and where!

If I understand the process correctly ... the orange is the unchanged
Lawsone molecule, just sitting in the skin cell.

To get it dark, the molecule to be changed one way or other.
Oxidized, percipitated, bound with the keratin. It's more apt to be
orange in the lower layers because that's where there's been little
oxygen penetration, and there wasn't therefore the opportunity for
reaction.

You can make it go dark by encouraging conditions for it to bind with
the keratin, oxidize or percipitate. Heat helps. If you get your
skin good and hot repeatedly, you can brown it down to deep layers,
terped or unterped.

You can make it go dark by terping. The longer the terps are in the
paste before application, the more of the dye molecules will be
terped. I think the unterped molecules are smaller, and penetrate
deeper. The terped moleclues don't breach as far, and you get a
finite boundry between orange and brown. So ... warm up your paste,
or let it sit longer before application. Both seem to work.

You can make it go darker farther within with sweat. Sweat has
ammonia and that percipitates the acidic Lawsone. You can make it dark
with other bases (so long as they'll penetrate without hurting you).

So ... my experience leads me to believe that you have to do some
pushing to get "brown to the bone" ... and you can do it with either
terp or non-terped.
