Hi guys, hows everything? Well I got my first tube of 0.1% Retin-A yesterday and everything seemed fine at first when I applied it in the morning, some skin peeled and I expected that. Later that night I applied some again and it burned my skin so severely that it turned red, almost like sunburn. I washed it off quickly and put on some milk moisturizer which took out the sting. This morning everything was fine again except for some tenderness when touching the skin. Obviously it was too strong because I wasn't going to put that on my skin again. I bought some 0.025% and applied it tonight successfully without much irritation, just minor. After 10 mins I applied some 4% HQ and that was that. So I realized that I have sensitive skin (owing to this experience and previously with the HQ). So just a warning for you guys out there higher percentage does not equal better results, most of the time it might set you back years. Well just thought I'd share that with yuall! Otherwise everything is fantastic, my skin seems really smooth now - more than ever, as for lightening we'll just have to wait till the end of the month!Cheers from TnT!
