Can’t really say much about what it does for my complexion but my skin feels decent after using it. Overall quality of these roof rack crossbars is pretty good. Amazons quality on diamonds seems to be questionable They go on and off easily and there are no sharp edges to catch on clothing. My boyfriend says crocks are the ugliest shoes ever. i love anker products but im really disappointed. I normally wear a 9 or 10 and the size I got fits perfect. I do think they may be a little wide, because I took a chance ordering these in a M width. I got a steal on these in the Volt Green. The straps connect with little hooks on the sides of the shoe.
