Caused server skin irritation, first time I used it my entire face swelled and stayed red and itchy for days. Have tried it since in tiny amounts mixed with a hydrating moisturiser to dilute it, I can definitely see the spots drying out and smaller than when I first applied but I can only leave it on for a few hours before having to wash it off as my skin becomes so sensitive to it leaving me red and blotchy. Would advise using small amounts and patch testing first.
