I use 0.05 and I have fair, sensitive skin.
I have quite a lot of trouble with it
flaking and a little irritation sometimes.
I can't use it every night. It helps to
add a little moisturizer with it if you
want to use it all the time. Unfortunately
for me, I need it close to the eye area and
I just can't use it there - my eyes burn
if I do. Good luck. It does work tho.
Renova with an occasional "lunch hour peel"
really seemed to help my skin.
