For what appears to be melasma, at least from the photo provided, you would be wise to consult with a board certified cosmetic dermatologist. The daily use of at-home, Rx topical medications, such as azelaic acid, tretinoin, hydroquinone, tranexamic acid, to name a few, combined with the inoffice use of a series of superficial peels, which may include high concentrations of salicylic or glycolic acid, Jessner's Solution, or low concentrations of TCA, can be extremely helpful for this kind of problem. I totally agree with your hesitancy to under laser treatments, as these, especially in SOC, run the risk of resulting in post-inflammatory hyperpigmentation, which could actually worsen the pigmentaty issue. Hope this helps and best of luck.
