I’m not a big believer in reinventing the wheel. Until something is proven to be better than something else in peer-reviewed studies and/or the marketplace, I’m not eager to become an early adopter and jump ship from what I’m already using. But that’s just me. As someone who does get sunspots from time to time, I will tell you, I like 15-20% vitamin C and 2% vitamin E as my “tyrosinase inhibitor”; exfoliation through nightly retinoids or glycolic acid once/week; and, yes, hydroquinone when the spots get really bad (but only as an on-the-spot treatment). I’m less excited by products like NIOD RE:Pigment, but I’m also not someone who’s googly-eyed at what’s new and sexy. If you are, it’s certainly not a bad product to try, but I would supplement it at least with a good solid exfoliant (like a nightly glycolic acid) and a daily vitamin CE serum.
