How many laser sessions do I usually need to see results for melasma and blemishes?

Maybe it's because the spring sun is so strong these days, but blemishes have really flared up on my cheekbones. ㅠㅠ They don't even cover up with concealer, so I'm looking into laser toning. Do people usually pay for a minimum of about 10 sessions? Package prices vary so much from clinic to clinic that I'm at a loss as to where to go. I would appreciate it if those who have recently seen results could share the approximate cost or treatment schedule!
