Obagi medium chemical peel(s) to treat lots of forehead wrinkles caused by frowning and sun damage. Is this strong enough?

I have lots of diaganol forehead wrinkles that are fine and static and have around $2000 to spend . I have visited a professional who has advised Obagi Chemical Peels (3-4 ) to treat these. Are these peels strong enough to help diminish these wrinkles significantly or are there other treatments I should consider at another practice? I would travel to America for the treatment offering the most significant outcome. I am male and fair skinned . Many thanks
