Well Tri and Ox soralen have been around for decades, and Tri is even mentioned in the PDA as being used for increasing skin pigmentation.
Also they are used for vertiligo, where a person has NO pigment in areas of their skin and it can return it to normal. Tri has almost no sides, which I can attest to, Ox you can get an upset stomach.

As to the action, they are the same as Melano, with the same results.
Just one is a simple pill you take for 2 weeks w/ set UV schedule and youre done.

both achieve the same results as to pigmentation and UV by stimulating melanin production. Melanin is melanin. Both need UV to work. Same sun protection, etc.

Id bet if Tri and Ox were promoted differently, Melano would lose favor quickly.

I mean if you got the same results, didnt have to inject, can only do it for 2 weeks and quit... its kinda a no brianer. Melano has a niche market, but there are easier ways to get the same darkness.

good luck though!
