Soko Glam – Triple C Lightning Liquid. This vitamin C rich product  is supposed to “brighten” skin, get rid of sun spots, melasma, acne scars and other pigmentation issues, according to its description. Soko Glam is a Korean Beauty brand based in New York, and the Korean beauty industry in general does have a very good reputation in the West. I can’t personally vouch for the efficacy of this product as I have never tried it. But it seems to get good reviews and has been designated as a “best seller” on the website.
