At least 6 months - maybe a whole year. I had laser on my face, but one day it dawned on me how much lighter and finer the hair was on my arms and belly, and how much less I had on my upper thighs. Mine was the best when I was on Yaz, Spiro & Met. Since I've dropped the Yaz, the arm & belly hair seems to have gotten slightly darker, but nothing like it used to be. |
