My first Vi Peel was done for alot of brown spots and brown areas (melasma), especially difficult was the side of my neck. Over time these areas got darker and were impossible to cover with makeup. The almost black area over my lip looked like dirt.
All of my brown spots and melasma is gone. It took 3 treatments, to treat it. And I still have maintenance Vi Peels now 3 times a year.
The biggest pro for me was knowing what days the peeling would be visible, so I could plan when to have the Vi Peel done. The first Vi Peel I had was without any Precision boosters. The 2nd and 3rd had the Precision booster in it. I now only do the Vi Peel with Precision boosters, because the results are even more dramatic.
