Imo he uses a superior vehicle (isopropyl alcohol and propylene glycol) so much more zinc will penetrate and take effect + he needles every week (there's one guy with pictures who had great results form needling + zix only). I can definitely see why he has good results with this zinc only version.
Btw the original vehicle of zix was always weak imo, water + ethyl alcohol isn't good enough for penetrating the skin imo.
@Rasher90 Do you have any side effects? And did you experience side effects from your older treatments like fina?
