Wow that is fast... How many units? I know some places over dilute it. Maybe you could try Dysport? It lasts longer for Botox for some. My Botox lasted almost 6 months last time.Anyone got any tips on how to make your botox last longer? I only had my last round on Jan 31st and it's already worn off quite significantly I love the results but I just can't afford doing it every 2 months (even if I could I wouldn't justify it tbh) and I hate being without it now!
