I heard it could in alkaline conditions but isn’t the skin slightly acidic? July 1, 2015 at 9:28 pm #95056 RandySMember Arbutus does bio-convert to hydroquinone but I’m sure of the conditions required for the conversion. This site has some details: http://www.kaviskin.com/info/a-arbutin.html But I don’t know how reliable they are. July 3, 2015 at 5:59 am #95065 jelnsqMember Thank you!!
