Neutrogena is a great brand--I have used the 110 SPF myself on my face when vacationing, and it works really well. I also continue to get new precancerous spots and have had both BCC and SCC over the last several years. Unfortunately, my damage continues because I mistreated my skin by tanning during my teens and 20s. The damage just keeps on rearing its ugly head.
It sounds like you are taking all the right steps--staying covered up and using sunscreen regularly--you are being proactive. Keep it up! I am keeping you in my thoughts and hoping for the all-clear at your next appointment!
