Follow instructions carefully.
This works for me.  I am very fair-skinned and as I have gotten older, I want to minimize age spotting on my face.  I use this every couple of days.  When it starts to burn, I wash it off right away (Use a washcloth.  You don't want to get this stuff in your eyes).  Then I slather on the sunscreen (SPF 70).  I love to walk and work in the garden. I don't wear a hat, and this combination of GA and sunscreen definitely does the job.
