Started tret on 3rd July. Applying every night, 0.5%. Slight sting when I use it for a few mins then nothing. Tiny bit of dry skin but no redness or breakouts. My sebaceous filaments on my chin that I've spent years trying to get rid of have almost disappeared in less than 10 days. Is it too good to be true? Still time for bad side effects? Or is it really as good as the Internet says?
